One of the most popular functions in Excel is the IF function. The IF function evaluates a condition and returns one value if the condition is true and another value if the condition is false. For example, you could have Excel look at the values in a column of order totals and return Yes if a quota is met and No if a quota isnβt met.
The syntax for the IF function looks like this: =IF(logical_test, [value_if_true], [value_if_false]).

                - Logical Test: Any value or expression that can be evaluated to TRUE or FALSE.
- Value If True: The value that is returned if Logical_test is TRUE. If omitted, TRUE is returned.
- Value If False: The value that is returned if Logical_test is FALSE. If omitted, FALSE is returned.
- Click OK when you're finished.
            
        
The IF function calculates and returns a value based on the evaluation of the logical test.
