Search for specific word in excel and paste it in the next column(not sure how to start)

Hey Guys,

I am looking for macro that will search column A for a specific word, in this case it will search for "NFF". If any cell in column A contains NFF, it will paste NFF into column B. For instance if A1 = "NFF, Upgraded" then B1 will show "NFF" I have attached a sample spreadsheet with a couple of examples. Sheet 1 is what I have, sheet 2 is what I need.


Thanks
