The Excel BITXOR Function

Bitwise Functions

The Excel Bitwise functions convert the supplied integer value(s) to binary form and then perform an operation on the individual bits.

The result is then converted back to an integer value before being returned.

Basic Description

The Excel BitXor function returns the bitwise 'XOR' (exclusive 'OR') for two supplied integers.

Note: the BitXor function was only introduced in Excel 2013 and so is not available in earlier versions of Excel.

The syntax of the function is:

BITXOR( number1, number2 )

where the supplied number arguments are positive integers.


BitXor Function Examples

Decimal-Binary Conversion

If you want to work through the stages of a bitwise 'XOR' operation you can use the Excel DEC2BIN and BIN2DEC functions to convert between decimal and binary forms.


Example 2

 Formula:
 AB
1=BITXOR( 9, 12 )(9 and 12 have binary forms 1001 and 1100)
2  
 Result:
 AB
15(decimal form of 0101)
