I have two spreadsheets where one (beta) contains a subset of rows of another (alpha). In both spreadsheets, I have a column that is a unique ID for each row. Is there a way to find alpha JOIN beta? I want to be able to identify each row in alpha that also appears in beta.
I’m doing this in Google spreadsheets if that helps.
Based on your comment on El Ronnoco’s answer, I’m assuming you just want a column of 1s and 0s indicating whether the item in
alphaappears inbeta. To do this all you need is the COUNTIF function.
