In Google Sheets, I have a filter that does this:
=FILTER(A:K, B:B <> "username1")
That works to exclude all rows that have username1 in the B cell. But I want to exclude a list of usernames. So I tried:
=FILTER(A:K, (B:B <> "username1")+(B:B <> "unsername2"))
But that excluded nothing. I would have thought that filter should exclude all rows with either of those usernames.
