Swapping Two Numbers

Written by Allen Wyatt (last updated May 2, 2026)
This tip applies to Excel 2007, 2010, 2013, 2016, 2019, 2021, 2024, and Excel in Microsoft 365

If you do any serious macro programming, there will eventually come a time when you want to swap the values in two numeric variables. In some versions of BASIC, there are commands that handle this. VBA leaves you to our own devices, however. The following technique should do the trick for most people:

    TempNum = MyNum1
    MyNum1 = MyNum2
    MyNum2 = TempNum

When completed, the values in MyNum1 and MyNum2 have been swapped, and TempNum doesn't matter since it was intended (by this technique) as a temporary variable anyway.

If you want to get fancy and do the swapping without using the intermediate TempNum variable, you could use this series of commands:

    MyNum1 = MyNum1 Xor MyNum2
    MyNum2 = MyNum2 Xor MyNum1
    MyNum1 = MyNum1 Xor MyNum2

This approach only works if MyNum1 and MyNum2 are whole numbers, meaning they are Integer or Long data types. (If you need to swap any other type of data, you need to use the previous approach in this tip.) It works because the Xor function basically "encodes" the difference between the values. So, successively applying Xor causes the variables to switch their values. (It is mind exploding to try to understand, but it does work.)
