You provide a logical test or condition that Excel will evaluate. If the condition is true, Excel will return the value specified in the
value_if_true parameter. If the condition is false, Excel will return the value specified in the
value_if_false parameter. The IF function is commonly used for tasks such as data validation, grading systems, and generating customized reports.
Q4: How can you apply filters to data in Excel?
