Comparing Strings

by Allen Wyatt
(last updated March 7, 2020)

It is not uncommon to compare strings in a macro. For instance, you may need to compare what a user typed with some pre-determined value. If you do this directly, you must take into consideration that the user may not have typed his (or her) string in the same way as you expected. Particularly vexing is the fact that the user may have mixed upper and lower case in their response.

The quickest and easiest way around this is to use either the UCase or LCase function on their input before you do the comparison. For instance, let's assume you prompt the user for the word "yes" to verify they want an action done. The following code will check the input, regardless of how the user typed it.

If LCase(UserIn) = "yes" then DoIt = True

The trick is to make sure your test string is either all uppercase or all lowercase, and then convert the user's input to that same case.

If you suspect that the user may inadvertently add spaces to either the beginning of ending of whatever they type as input, then you can enhance the statement by also including the Trim statement to get rid of the spaces:

If Trim(LCase(UserIn)) = "yes" then DoIt = True
