XOR

Definition: The XOR function in Excel is used to compare two logical expressions and returns TRUE if only one of the expressions is TRUE.

Syntax: ==XOR(logical1, [logical2], …).

Situation: This formula is appropriate in situations where you need to compare two logical expressions and return TRUE if only one of the expressions is TRUE.

Example: If you have two logical expressions in cells A1 and A2 and you want to determine if only one of the expressions is TRUE, you would use the formula =XOR(A1, A2). This would return TRUE if only one of the expressions is TRUE.
