I have a spreadsheet that contains a column with 4 numbers/characters. For example, "AB2C", "2222", "YYYY", etc. I want to check each cell in the column to see if the cell contains any of these letters: B,C,D,E,F,G,H,J,K,L,M,N,O,P,R,S,T,U,V,W,X. Is there a formula that can do that? If so, what do I need to do? Any help is greatly appreciated.
