βοΈ Summary: Conditional formulas, which display different results based on conditions, are essential for practical Excel work. This guide covers a range of functions and techniques, including IF, IFS, SWITCH, AND/OR, and conditional formatting, to help you use them effectively in real-world situations.
β 1. Basic Conditional Function: IF
=IF(condition, value_if_true, value_if_false)
- The most fundamental conditional function
- Useful in many situations, such as grading criteria and budget overruns
π 2. Multiple Conditions: IFS
=IFS(condition1, result1, condition2, result2, ...)
- No need to nest multiple IF functions
- However, be careful not to overlap conditions
π 3. Comparing Multiple Conditions: SWITCH
=SWITCH(value, value1, result1, value2, result2, ...)
- Useful when comparing multiple cases for a single value
- Example: Displaying a message for each grade level
π 4. Combined Conditions: AND / OR
=IF(AND(condition1, condition2), result1, result2)
- AND: Returns TRUE when all conditions are met
- OR: Returns TRUE when at least one condition is met
π¨ 5. Conditional Formatting
- Home β Conditional Formatting β New Rule
- Automatically change cell fill color and font color based on values
- Example: Green for scores of 80 or higher, red for scores of 60 or lower
Practical tip: Nest AND/OR inside IF to handle even complex situations easily!
π Frequently Asked Questions (FAQ)
- Q1. What if my IF formula becomes too long?
Replace it with IFS or split the formula across cells - Q2. My conditional formatting is not working!
Check whether the=sign is missing at the beginning of the formula - Q3. How do I distinguish between OR and AND?
AND requires all conditions to be met, while OR returns TRUE if at least one condition is met - Q4. When is SWITCH useful?
When you can divide options more simply than with IF - Q5. How many levels of nested conditional formulas are possible?
It varies by version, but Office 365 is much more flexible
