XOR

XOR(logical1 [,logical2] [..])

Returns the logical exclusive OR for any number of arguments.

logical1	The first logical value or condition.
logical2	(Optional) The second logical value or condition.

REMARKS

* Added in Excel 2013.
* This function returns either True or False.
* This function is not case sensitive when matching text strings.
* This function does not support wildcards (? and *).
* This function will return True when the number of arguments that evaluate to True is odd.
* This function will return False when the number of arguments that evaluate to True is even.
* The logical values can be constants, logical equations, cell references or named ranges.
* You can use this function to see if a value occurs in an array.
* If any argument does not evaluate to either True or False, then #VALUE! is returned.
* You can have a maximum of 254 arguments (not 255).
* You can use the AND function to return the logical AND for any number of arguments.
* You can use the NOT function to return the opposite of a True or False value.
* You can use the OR function to return the logical OR for any number of arguments.
