Excel 2010 doesn’t have an XOR function. The newer versions do. I have needed this form of logic a couple of times recently and I found a good tip here.
XOR works like this.
So, if you don’t have an XOR function you can write a long version of the XOR as follows
This is how the XOR operation is defined if you study boolean logic. I did 25 years ago.
But there is a clever way to do it in Excel.
The web page lined above noted that the equivalent can be done from the observation that XOR is nothing but <> (the not equal to sign).
So, instead of going crazy with brackets writing the lengthy formula above. you can just use
One aside that I found out. You need to be careful with your brackets. I found out that
Is not the same as this
Hint: Use the second form with the extra brackets.
