Question : How do I compare two columns in Excel 2007?

I have two columns of information that I have brought in from two different source and I want to compare the columns against one another and highlight the information in one column that is missing from the other column. Example:
Column 1           Column2
Zone 101          Zone 101
Zone 102          Zone 103
Zone 103
Is there a way to compare Column 1 against Column 2 and highlight the cell that contains Zone 102?

You can compare two ranges using MATCH function

=MATCH(LookupValue, LookupArray, MatchType) --> use 0 for exact match

Please note that there will be no exact match because there's a space before the first visible character.
You can use trim function. =TRIM(TEXTREFERENCE) then copy, paste as values. Apply this before using Match function.
