Match formula

Hello!

Column A Sheet 1 has a repetitive data (about 300,000 rows). Column A Sheet 2 has the same data (about 50 rows).  I need a formula that says if A1 from Sheet 1 matches A1 Sheet 2, then “exclude”, otherwise “keep it”.

thanks

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
