Syntax of Excel IF Statement: The syntax of If Function in Excel is as follows: =IF (Logic_Test, Value_if_True, Value_if_False). Here, â Logic_Test â refers to the expression that is to be evaluated. â Value_if_True â is the output of IF Statement if the â Logic_Test â is TRUE.
You can have as many ElseIf clauses as you want in a block If, but none can appear after an Else clause. Block If statements can be nested; that is, contained within one another. When executing a block If (second syntax), condition is tested. If condition is True, the statements following Then are executed. If condition is False, each ElseIf condition (if any) is evaluated in turn. When a True condition is found, the statements immediately following the associated Then are executed. If none of the ElseIf conditions are True (or if there are no ElseIf clauses), the statements following Else are executed.
