The IF function is one of the most commonly used logical functions in DAX for Power BI. It evaluates a condition and returns either a True or False result, allowing you to display different values or calculations based on that outcome. When you only have two possible results, the IF function is simple and effective. However, when your logic involves three or more conditions, you often need to nest multiple IF statements. This can quickly become complicated, difficult to read, and challenging to maintain.
In the world of Power BI and DAX (Data Analysis Expressions), writing clean, efficient, and understandable formulas is crucial for developing high-performance dashboards and analytics models. One of the most common logical constructs in DAX is the IF statement, used to perform conditional evaluations. However, as your logic becomes more complex, nesting multiple IF statements can quickly make your DAX code unreadable and difficult to maintain. This is where the SWITCH function shines as a superior alternative, offering a more structured and legible way to handle multiple conditions.
Understanding the Elegance of SWITCH in DAX
The SWITCH function in Power BI DAX acts like a streamlined alternative to multiple IF statements, functioning much like a “case” or “switch” statement in traditional programming languages. It evaluates a given expression once and then compares it against a series of specified values. When a match is found, the corresponding result is returned. If none of the specified conditions are met, a default result can also be provided.
This method not only enhances clarity but also significantly reduces the potential for logical errors that often arise when nesting many IF statements. With SWITCH, your formulas are not only easier to read, but also more intuitive to debug and optimize, leading to improved performance and reduced development time in Power BI.
Practical Structure of the SWITCH Function
The general syntax of the SWITCH function in DAX is:
php-template
CopyEdit
SWITCH(<expression>, <value1>, <result1>, <value2>, <result2>, …, [<default>])
Here, the <expression> is evaluated once. Then, DAX checks each <value> in order. If a match is found, it returns the corresponding <result>. If no matches occur and a default value is provided, it returns that default. This clear structure is vastly preferable to deciphering deeply nested IF conditions.
Real-World Example of SWITCH Usage
Imagine a scenario where you want to categorize sales regions based on specific country codes. Using nested IF statements would look something like this:
less
CopyEdit
IF([CountryCode] = “US”, “North America”,
IF([CountryCode] = “DE”, “Europe”,
IF([CountryCode] = “IN”, “Asia”, “Other”)))
While this is still somewhat readable, adding more country codes increases the nesting and makes debugging harder. Here’s how the same logic is handled using SWITCH:
arduino
CopyEdit
SWITCH([CountryCode],
“US”, “North America”,
“DE”, “Europe”,
“IN”, “Asia”,
“Other”)
The SWITCH version is immediately more readable and clearly shows the mapping from country codes to regions. There’s no question of which IF corresponds to which condition, and you can quickly add or remove conditions as needed.
Enhanced Readability and Maintainability
One of the major pain points for Power BI developers arises when troubleshooting long chains of nested IF functions. The logic quickly becomes convoluted, especially in larger projects involving dynamic reporting and business logic. The SWITCH function, with its flat structure, allows developers to logically organize conditions in a single expression.
When working in collaborative environments or returning to a report after weeks or months, SWITCH functions are far more maintainable and intelligible. This increases team productivity and minimizes the risks of introducing logical bugs due to misinterpretation.
Performance Advantages in Large Models
From a performance standpoint, the SWITCH function also offers marginal benefits in large-scale models. Since the expression is evaluated only once and compared to constant values, this can reduce computational load in certain scenarios compared to multiple IF statements where each condition is evaluated independently. Although the performance gain is often minor, in high-volume datasets or complex business rules, every millisecond counts, especially when refreshing visuals or exporting large sets of insights.
Optimizing Data Models with SWITCH in Power BI
In modern business intelligence workflows, reducing complexity in your DAX formulas helps with model optimization. When designing data models for Power BI, using SWITCH instead of nested IF helps streamline your calculated columns and measures. Clean DAX expressions directly contribute to faster report loading times, smoother slicer interactivity, and a better user experience for stakeholders.
Additionally, when integrated with other DAX functions like CALCULATE, FILTER, or SELECTEDVALUE, SWITCH becomes an even more powerful tool for creating context-sensitive logic within measures or KPIs.
Leveraging SWITCH for Better Data Storytelling
Switching to SWITCH (pun intended) doesn’t just improve formula management; it directly enhances your ability to tell compelling data stories. Business users consuming reports may not see your DAX code, but the impact is tangible in how quickly they can filter, analyze, and understand the underlying data.
For example, when you’re calculating customer satisfaction tiers, instead of using a multi-nested IF construct, a SWITCH expression can quickly assign levels like “Poor,” “Average,” “Good,” and “Excellent” based on numeric scores. This kind of structured classification plays a crucial role in dynamic dashboards and drill-through reports.
When to Avoid SWITCH
While SWITCH is powerful, it does have limitations. It is best suited for discrete value comparisons. If you need to evaluate ranges of values (e.g., if a number is between 50 and 75), then using IF, or a combination of IF and AND, may still be necessary. In such cases, a hybrid approach may be most effective—using SWITCH where values are clearly mapped, and conditional logic for more complex comparisons.
Make Your DAX More Intelligent with SWITCH
Adopting the SWITCH function in Power BI DAX is not just a matter of style—it’s a fundamental enhancement to how your business logic is built, understood, and maintained. By replacing deep chains of nested IF statements with SWITCH, you unlock a new level of clarity, performance, and professionalism in your data models.
Our site provides deep guidance and tutorials to help Power BI users evolve their DAX practices with simplicity and sophistication. Incorporating SWITCH into your toolkit is a pivotal step in crafting high-quality analytical solutions that scale well and serve real-world decision-making.
If your goal is to build robust, readable, and high-performing Power BI reports, integrating the SWITCH function into your everyday DAX development is a smart and future-proof move.
Using SWITCH with TRUE() in Power BI DAX for Advanced Logical Conditions
In Power BI development, the ability to write clean, maintainable, and performant DAX expressions is essential for delivering impactful analytics. While the SWITCH function is widely appreciated for its elegance and readability when handling exact matches, many developers are unaware that SWITCH can also be adapted to support inequality comparisons. By combining SWITCH with the TRUE() function, you can achieve a flexible, expressive approach to conditional logic—replacing even the most intricate chains of nested IF statements.
This method enables Power BI users to maintain readable formulas while incorporating logical expressions like greater than, less than, or range-based conditions within a single, streamlined structure.
Understanding the Limitation of Standard SWITCH Logic
The default behavior of the SWITCH function is based on evaluating an expression against a series of constants. It works well when checking for exact matches, such as mapping numerical codes to category labels or assigning descriptive text to specific values. However, it does not directly support comparisons such as “greater than 50” or “less than or equal to 100.”
For example, the following DAX formula would fail to handle inequalities:
SWITCH([Score],
90, “Excellent”,
75, “Good”,
60, “Average”,
“Poor”)
This structure only works for exact values like 90 or 75—not for score ranges. In real-world business use cases such as grading systems, performance evaluations, or risk segmentation, these inequalities are critical.
Introducing TRUE() for Logical Evaluation in SWITCH
To unlock the full potential of SWITCH, you can utilize the TRUE() function as the expression being evaluated. Instead of comparing a single expression to multiple values, this technique evaluates logical tests and returns the corresponding result for the first condition that evaluates to true.
Here’s the general syntax for this advanced approach:
SWITCH(TRUE(),
<condition1>, <result1>,
<condition2>, <result2>,
…,
<default result>)
This formulation turns SWITCH into a cascading decision tree based on Boolean logic. Each condition is evaluated in order, and as soon as one returns true, the corresponding result is provided.
Real-World Example: Categorizing Scores into Performance Bands
Consider a scenario where you want to classify test scores into qualitative performance categories. You could write this using nested IF statements, but it quickly becomes unreadable:
IF([Score] >= 90, “Excellent”,
IF([Score] >= 75, “Good”,
IF([Score] >= 60, “Average”, “Poor”)))
Here’s how you can achieve the same result more clearly with SWITCH and TRUE():
SWITCH(TRUE(),
[Score] >= 90, “Excellent”,
[Score] >= 75, “Good”,
[Score] >= 60, “Average”,
“Poor”)
This version is easier to follow, especially when more conditions are added. The readability of each range condition stands out, and it eliminates the need to mentally untangle nested logic blocks.
Applications in Dynamic Business Scenarios
The combined use of SWITCH and TRUE() proves particularly powerful across a range of business intelligence use cases. Whether you’re dealing with financial thresholds, risk categorization, employee performance scores, or customer lifetime value groupings, this technique allows you to model conditions that reflect real-world business logic.
For example, a financial model might classify accounts based on outstanding balance:
SWITCH(TRUE(),
[Balance] > 100000, “High Risk”,
[Balance] > 50000, “Medium Risk”,
[Balance] > 10000, “Low Risk”,
“No Risk”)
This kind of logic, cleanly embedded within a single SWITCH expression, supports dynamic segmentation in reports and dashboards.
Simplifying Maintenance and Enhancing Scalability
One of the often-overlooked benefits of using SWITCH(TRUE()) in DAX is how it enhances the maintainability of your Power BI model. As your report evolves and logic changes, updating a SWITCH block is straightforward. Each line is independent of the next, unlike nested IF statements where altering one condition can require reworking the entire hierarchy.
This modular approach enables better collaboration between developers and analysts. New business rules can be added without risking regressions in unrelated parts of the logic. When scaling to enterprise-level reporting, these efficiencies reduce development time and minimize errors in business-critical calculations.
Performance Considerations with SWITCH and TRUE
While the SWITCH(TRUE()) approach does introduce multiple logical tests, it still performs efficiently in most Power BI models—especially when the conditions involve simple comparisons on indexed or pre-calculated columns. It evaluates each condition in order, stopping when the first true result is found, similar to how a chain of IF statements functions.
When used judiciously, this technique won’t negatively impact performance and can actually simplify complex expressions that would otherwise be difficult to troubleshoot.
Enhancing User Experience through Clean Logic
Clean DAX logic leads to cleaner user interfaces. When business logic is expressed clearly in the back end, users of your dashboards and reports benefit from more reliable visuals, accurate KPI flags, and consistent slicer behaviors. The SWITCH(TRUE()) technique contributes to this clarity by abstracting complex logic into a human-readable structure.
This is particularly impactful in scenarios like custom tooltips, conditional formatting, or calculated labels where expressions influence what users see at a glance. Ensuring these conditions are accurate and easy to manage directly contributes to the quality of your user-facing content.

Transforming Conditional Logic in Power BI with SWITCH and TRUE
In the dynamic world of Power BI, DAX (Data Analysis Expressions) serves as the backbone for creating intelligent, responsive, and data-driven logic. As datasets and business rules grow in complexity, developers and analysts often find themselves wrestling with deeply nested IF statements—structures that are difficult to read, harder to debug, and nearly impossible to scale gracefully. Fortunately, there is a more refined solution for handling conditional logic: combining the SWITCH function with the TRUE() function in DAX.
This combination creates a flexible decision-making structure that supports inequality evaluations and complex conditions, while remaining far more readable than a tangle of IF blocks. It empowers report developers to build resilient, adaptable logic in Power BI dashboards and models with significantly less effort.
Why Traditional Nested IF Statements Can Be a Hindrance
The IF function has its place in DAX for straightforward decisions, but it quickly becomes cumbersome when layered. A formula evaluating three or more conditions can become a spaghetti mess, where every opening parenthesis must be matched precisely and the logical flow becomes hard to interpret.
For example, suppose you’re building a formula to categorize sales revenue:
IF([Revenue] >= 100000, “High”,
IF([Revenue] >= 50000, “Medium”,
IF([Revenue] >= 20000, “Low”, “Minimal”)))
While the above logic works, it’s not scalable. If a new revenue category needs to be added or thresholds change, the entire structure has to be revisited. Moreover, mistakes in logic or missing parentheses can introduce silent errors or incorrect outputs—difficult issues to track down, especially under deadlines.
Introducing a More Readable Alternative: SWITCH with TRUE
To enhance both maintainability and clarity, Power BI developers can employ the SWITCH(TRUE()) construct. Unlike standard SWITCH, which is built for evaluating exact matches, this technique evaluates each condition sequentially until it finds one that is true. It provides the best of both worlds—concise structure and logical flexibility.
Here’s how the above revenue classification example looks with SWITCH(TRUE()):
SWITCH(TRUE(),
[Revenue] >= 100000, “High”,
[Revenue] >= 50000, “Medium”,
[Revenue] >= 20000, “Low”,
“Minimal”)
This format is significantly more readable, logically elegant, and easy to extend. Each line functions independently, making it easy to rearrange conditions, add new categories, or adjust thresholds without disrupting the whole formula.
Expanding the Use Case for SWITCH and TRUE
The versatility of SWITCH(TRUE()) extends beyond simple value ranges. It is an excellent choice when handling tier-based logic, risk ratings, scoring systems, and dynamic classifications. In financial reporting, for instance, this technique can categorize profit margins, flag performance outliers, or segment customers based on calculated metrics.
Here’s a practical example involving profit margins:
SWITCH(TRUE(),
[Margin %] < 5, “Critical”,
[Margin %] < 15, “Below Target”,
[Margin %] < 25, “Healthy”,
[Margin %] >= 25, “Excellent”,
“Undetermined”)
This structure is not only intuitive to read but also communicates business logic clearly to other team members. When handed off to another developer or analyst, the logic behind each tier is immediately obvious, eliminating the need for separate documentation or translation.
Enhanced Maintainability and Model Scalability
Another reason to embrace the SWITCH(TRUE()) approach is its innate maintainability. In Power BI, your models are living components of your business intelligence architecture. They evolve as KPIs shift, strategies adapt, or business units request custom metrics. Nested IF functions tend to decay over time—becoming fragile, brittle, and error-prone with every added condition.
Conversely, the SWITCH structure with TRUE() allows for modular updates. You can add, remove, or update a condition with confidence, knowing it won’t impact the surrounding logic. This improves both speed and accuracy in long-term model maintenance, which is especially valuable in collaborative or enterprise-scale environments.
Visual Logic and UX Enhancements in Power BI Reports
DAX logic not only affects calculations—it directly influences how visuals behave, respond, and communicate information. Conditional logic using SWITCH(TRUE()) enhances user-facing features like:
- Dynamic titles based on context
- Custom labels for charts and tooltips
- Conditional formatting for KPIs and metrics
- Category tags in matrix or table visuals
Imagine a Power BI report that adjusts the background color of cells based on operational efficiency. Using SWITCH(TRUE()), you can generate clean and reliable category labels, which are then linked to formatting rules in your visuals. This leads to more coherent storytelling and more meaningful user interaction.
Performance Efficiency in SWITCH vs Nested IF Statements
From a performance perspective, SWITCH(TRUE()) is generally as fast—or sometimes faster—than deeply nested IF statements, especially when your logic contains a moderate number of branches. Because conditions are evaluated in sequence and stop after the first match, DAX avoids unnecessary computation. In scenarios where your dataset is large and your measures are reused in many visuals, the readability and maintainability of SWITCH(TRUE()) pay off in performance tuning over time.
Moreover, this approach helps reduce the risk of hidden computational complexity—where performance bottlenecks arise from unintuitive code structure rather than the volume of data.

Future-Proof Your Power BI Development with Smarter Logic
In today’s fast-paced analytics environments, developers and analysts need solutions that are not only functional but sustainable. By using SWITCH and TRUE() together, you build DAX expressions that are resilient, scalable, and aligned with best practices. Whether you’re modeling financial forecasts, automating decision logic, or building executive dashboards, this technique empowers you to code with clarity and precision.
Power BI is more than a reporting tool—it’s a platform for creating rich analytical ecosystems. Equipping yourself with efficient, transparent logic structures like SWITCH(TRUE()) ensures that your models can evolve as your organization grows, without sacrificing performance or usability.
Redefining DAX Logic Efficiency in Power BI Reports
In today’s data-driven business landscape, Power BI has become a critical tool for transforming raw data into strategic insights. But the power of Power BI doesn’t solely lie in its sleek visuals or interactive dashboards—it also depends on the logic that powers these outputs. For DAX developers and report designers, optimizing logical expressions is fundamental to building robust, scalable, and easy-to-maintain data models.
One significant step toward this goal is moving away from deeply nested IF structures and embracing a cleaner, more structured alternative: the combination of the SWITCH function with the TRUE() function in DAX. This approach is not only a technical refinement but also a best practice in modern Power BI development.
Why Complex Nested IFs Create Long-Term Problems
At first glance, using multiple IF statements to manage decision logic might seem intuitive. You write a condition, test a value, and assign an outcome. However, as the number of conditions increases, the structure of your DAX formulas can quickly spiral into a complicated, hard-to-read hierarchy of brackets and logic blocks.
Take, for example, a pricing model that categorizes transaction size:
IF([Amount] > 1000, “Premium”,
IF([Amount] > 500, “Standard”,
IF([Amount] > 100, “Basic”, “Minimal”)))
Although this code is functional, its maintainability becomes a liability. Updating logic, troubleshooting errors, or even deciphering its intent a few weeks later can be surprisingly difficult. These layers of logic, when stacked excessively, not only increase the cognitive load but also slow down collaborative development.
Embracing SWITCH and TRUE for Logical Precision
The SWITCH(TRUE()) construct offers an elegant solution to this problem. By allowing each logical test to exist independently within a flat structure, it dramatically improves the readability and structure of your code. This format turns complex conditional logic into a sequence of clearly ordered conditions, each evaluated until one returns true.
Here is the equivalent of the pricing model using SWITCH(TRUE()):
SWITCH(TRUE(),
[Amount] > 1000, “Premium”,
[Amount] > 500, “Standard”,
[Amount] > 100, “Basic”,
“Minimal”)
This version not only looks cleaner, but each line can be interpreted and modified independently. This separation of conditions makes your DAX expressions less error-prone and far more adaptable over time.
Use Cases Where SWITCH(TRUE()) Excels
The advantages of SWITCH(TRUE()) aren’t limited to readability. This method of logical evaluation becomes indispensable when building decision structures based on:
- Tiered pricing models
- Employee performance evaluations
- Grading scales or assessment frameworks
- Revenue classification thresholds
- Customer segmentation based on metrics
- Operational risk tiers in compliance reporting
For instance, in a sales performance model, this logic could be written as:
SWITCH(TRUE(),
[Sales] >= 100000, “Top Performer”,
[Sales] >= 75000, “High Achiever”,
[Sales] >= 50000, “On Track”,
[Sales] >= 25000, “Needs Support”,
“Below Expectations”)
This logic is not only transparent but also lends itself to easy expansion if new tiers are introduced in the business process.
Enhancing Maintainability in Business Models
One of the unsung benefits of SWITCH(TRUE()) in Power BI is how it transforms long-term maintainability. In enterprise environments, where dashboards evolve regularly and are often handled by multiple team members, reducing the complexity of DAX logic is a strategic win. Logic written using SWITCH(TRUE()) is modular, intuitive, and far less prone to breakage during updates.
Adding a new condition or adjusting existing thresholds can be done without risk of disturbing the flow of the rest of the expression. In contrast, a change in a nested IF structure often requires a full audit of the entire logic tree to avoid unintended consequences.
Improved Model Performance and Readability
Although the SWITCH(TRUE()) approach may perform similarly to traditional IF blocks in small datasets, it can offer performance advantages when scaled. Because SWITCH evaluates conditions in a sequence and exits after the first true condition is found, it can eliminate unnecessary evaluations and optimize calculation time across visuals and report interactions.
From a user experience perspective, this also ensures smoother responsiveness in complex reports. Well-structured logic is not just a back-end enhancement—it directly impacts how fluid and interactive your dashboards feel to end-users.
Unlocking Conditional Formatting and Visual Logic
DAX logic doesn’t just drive calculations—it plays a critical role in how your visuals behave. With SWITCH(TRUE()), you can simplify logic used in conditional formatting rules, tooltips, dynamic labels, and category coloring. Whether you’re flagging outliers, assigning qualitative labels, or dynamically adjusting visual states, this method supports more intuitive development.
A conditional formatting example could look like this:
SWITCH(TRUE(),
[ProfitMargin] < 5, “Red”,
[ProfitMargin] < 15, “Orange”,
[ProfitMargin] < 25, “Yellow”,
“Green”)
This structure is incredibly effective when driving formatting rules across matrix visuals, cards, or bar charts—making your data not only informative but also visually engaging.

Build Long-Term Value Through Logical Optimization
Improving how you write DAX isn’t just about aesthetics—it impacts data quality, collaboration efficiency, and analytical accuracy. When you switch from nested IF statements to SWITCH(TRUE()), you invest in clarity and long-term stability. It’s a shift toward best practices that makes your models easier to scale, your reports more robust, and your logic more accessible to others.
Whether you’re a Power BI beginner refining your first model or an advanced user optimizing enterprise dashboards, this approach is a valuable tool in your data development toolkit.
Elevating DAX Logic Using SWITCH and TRUE in Power BI
Modern business intelligence depends heavily on flexible, efficient data models. Power BI, with its powerful DAX (Data Analysis Expressions) engine, enables professionals to build highly responsive dashboards and interactive reports. However, the effectiveness of these reports hinges on the quality of the logic that drives them.
Among the most impactful DAX improvements developers can make is adopting the SWITCH(TRUE()) pattern over traditional nested IF statements. This method not only enhances readability but also simplifies troubleshooting, improves collaboration, and scales easily as data models evolve. It is a subtle yet transformative shift for anyone who works with logic-intensive Power BI formulas.
The Challenge with Nested IF Statements in DAX
When handling conditional logic, many Power BI users default to using the IF function. It’s straightforward and familiar: test a condition and return a result. However, when multiple conditions are required, users often nest several IF statements within one another. Although functional, this approach quickly becomes difficult to manage.
Take the following example:
IF([SalesAmount] >= 100000, “Top Tier”,
IF([SalesAmount] >= 75000, “Mid Tier”,
IF([SalesAmount] >= 50000, “Entry Tier”, “Below Target”)))
This formula might seem manageable at first glance, but as you add more layers or adjust thresholds, the logic becomes convoluted. Debugging or modifying one piece often affects others, leading to unnecessary complexity and increased risk of error.
Introducing SWITCH with TRUE for Better Logic Handling
The SWITCH(TRUE()) pattern in DAX presents a far more structured and logical alternative. It allows each condition to be evaluated independently in a sequence, improving both readability and flexibility. Here’s the same logic from the earlier example, rewritten using this more maintainable pattern:
SWITCH(TRUE(),
[SalesAmount] >= 100000, “Top Tier”,
[SalesAmount] >= 75000, “Mid Tier”,
[SalesAmount] >= 50000, “Entry Tier”,
“Below Target”)
Every condition here stands on its own. There’s no need to track parentheses or mentally unpack multiple layers. This kind of flat logic structure is not only easier to write but also dramatically easier to modify or extend.
Real-World Use Cases for SWITCH and TRUE in Power BI
The benefits of this approach are not just theoretical. Many practical scenarios require multi-condition logic, and SWITCH(TRUE()) excels in these cases. Common applications include:
- Assigning performance levels to employees based on target achievements
- Grouping customers by purchase history or engagement scores
- Tagging financial metrics into profitability bands
- Creating dynamic grading systems in training dashboards
- Flagging operational risk thresholds across departments
For example, let’s consider a financial metric that categorizes margin performance:
SWITCH(TRUE(),
[Margin] < 5, “Critical”,
[Margin] < 15, “At Risk”,
[Margin] < 25, “Satisfactory”,
[Margin] >= 25, “Healthy”,
“Undetermined”)
This formula makes logical sequencing clear and direct, enabling business users and analysts to understand what each range signifies without decoding deeply nested logic.
Improving Maintainability and Collaboration in DAX
As data models grow and Power BI projects become more collaborative, writing DAX that others can understand is a necessity. Nested IF structures often require a walkthrough just to understand what the formula is doing, let alone what needs to be changed.
Using SWITCH(TRUE()) makes DAX logic self-explanatory. Team members can glance at your formula and instantly see the decision path. Adding new business rules becomes a matter of inserting another condition line—no unraveling of nested brackets required.
This readability dramatically improves code maintainability and fosters better collaboration between analysts, data engineers, and decision-makers. It’s a step toward more agile and resilient data practices.
Performance Optimization and Logical Efficiency
While the performance difference between IF and SWITCH might be negligible for small datasets, models with thousands or millions of rows benefit from the streamlined execution path of SWITCH(TRUE()). Once a matching condition is found, evaluation stops. This can reduce processing overhead, particularly in complex dashboards or when using calculated columns that depend on conditional logic.
Furthermore, SWITCH reduces redundancy in evaluation. Instead of rechecking similar expressions multiple times within nested structures, the conditions can be evaluated with clearer intent and minimal repetition.
Enhancing Visual Behavior in Reports Using SWITCH Logic
DAX expressions often influence how Power BI visuals behave. Whether it’s defining categories, customizing tooltips, or triggering conditional formatting, logic clarity is essential. The SWITCH(TRUE()) method makes it easier to control the visual presentation of data.
For example, you might use it in a calculated column that informs cell coloring in a matrix:
SWITCH(TRUE(),
[Efficiency] < 50, “Low”,
[Efficiency] < 75, “Medium”,
[Efficiency] >= 75, “High”,
“Unknown”)
This classification feeds directly into conditional formatting rules, helping stakeholders instantly identify trends and anomalies through visual cues.
