In this article, we will learn about how to use the BITXOR function in Excel.

**Scenario:**

BITXOR function in excel perform the BITWISE XOR operation between the two decimal numbers and returns the decimal number after the operation performed.

XOR operation is a logical operator used in communication processes. AND operator is performed over the 2 bits ( 0 or 1 ). The operation takes place like in table shown below.

Bit 1 | Bit 2 | AND operation |

0 | 0 | 0 |

0 | 1 | 1 |

1 | 0 | 1 |

1 | 1 | 0 |

Here the decimal numbers be changed in binary and the OR operation be performed over each bit with the corresponding bits.

Decimal | Binary | |

number1 | 2 | 010 |

number2 | 4 | 100 |

result | 6 | 110 |

The different highlighted bits is to show how the BITWISE XOR operation occurs between the two numbers. Use the DEC2BIN function ( decimal to binary conversion) & BIN2DEC function ( binary to decimal conversion) to understand BITXOR function’s result step by step in Excel. For example, Binary representation of 10 is 1010 and Binary representation of 7 is 111 and if we compare which positions are not equal we will get :-

1010

0111

-------

yyny

4301

so that means 1*(2^3)+1*(2^2)+1*(2^0) = 8+4+1=13

so if we use the formula directly as =BITXOR(10,7) will get the similar result as 13.

**BITXOR function**

The BITXOR function returns a bitwise 'XOR' of two numbers.

**Syntax:**

=BITXOR ( number1, number2) |

number1 : a positive integer number of base 10 (decimal number).

number2 : a positive integer number of base 10 (decimal number).

**Example : **

All of these might be confusing to understand. Let's understand how to use the function using an example. Here is the excel representation of the function. The below image shows the result in B4 cell taking input B2 and B3 cell.

**Use the formula :**

=BITXOR (B2, B3) |

As you can see, the Bitxor operation of 2 and 10 returns 8.

Now let’s get more understanding of the function via using them in some examples.

Here we have some values as number1 & number 2 in Columns. We need to get the Bitwise 'XOR' operation on the given numbers

Use the formula :

=BITXOR (A2, B2) |

A2 : number provided to the function as cell reference

B2 : number provided to the function as cell reference

The Bitwise 'XOR' operation on 7 ( 111 ) & 5 ( 101 ). Resulting binary number would be 101. So the decimal number representing 101 is 5.

Now copy the formula to other cells using the **Ctrl + D** shortcut key.

As you can see here the BITXOR function returns the result of the input values.

Here are some observational notes using the BITXOR function in Excel.

Notes :

- Numbers can be given as arguments to the function directly or using the cell reference in excel.
- The numbers must be a valid decimal number between 0 & 281474976710655.
- The function returns the #NUM! Error, If either of the decimal numbers is less than 0 or greater than 281474976710655.
- The function returns the #VALUE! Error, If the input number is text or non-numeric.
