I have two lists of names where the first column is the master list and the second column is a partial list of those people.

How do I create a third column listing only those people from the first column that are not in the second column (i.e., removing duplicates)?

Assuming that A2:A10 contains the first list, and B2:B6 contains the second list, try the following formula which needs to be confirmed with CONTROL+SHIFT+ENTER...

C2, copied down:

=INDEX($A$2:$A$10,MATCH(TRUE,IF(ISNA(MATCH($A$2:$A$10,$B$2:$B$6,0)),ISNA(MATCH($A$2:$A$10,$C$1:C1,0))),0))

Hope this helps!

Note that I've edited the formula. Also, the formula will not return any values that appear in the second list and not the first...
