For a problem, I need to list all of the possible combinations of
uppercase/lowercase letters.
Each combination should have all 26 letters of the alphabet in either
uppercase or lowercase form. There are over 67million combinations.

Is there a way to get excel to list these combinations?

Check your other thread.
