I have 2 spreadsheets with exactly the same number of columns. They are
lists of names and addresses of donors to our organization. List 2 is a
smaller list of current donors and list 1 is a larger list of all donors from
the past. I want to send letters to all old donors who are not in list 2.
So I want to compare the 2 lists and eliminate from list 1 those donors who
are in list 2. The first column in each list is a unique Donor number. Can
I do this in Excel without having to buy a third party program? ANY help
would be GREATLY appreciated.
