Hi, I am new and would be most grateful if someone could tell me how to solve a problem. I have a spreadsheet with approximately 1100 names that I use for a mail merge. I have separate spreadsheet including about 200 of those same names. I don't want the 200 names in the smaller spreadsheet to be included in the mail merge. How can I compare the two and eliminate the 200 names from my master spreadsheet? Thank you, Donna
