Thanks Dave, it was a bit over my head but I finally figured it out.

I have two mail lists on excel. The first has 16,000 names, the second has
about 6,000. I need to remove the 6,000 from the 16,000 as they all appear
in the big list as well. How do I extract those 6,000 entries from the larger
list? My expected result is a mailing list with 10,000 names.
