title: How can I filter all values in a CSV spreadsheet that don't match one of hundreds of values from another spreadsheet?
body: <p>I'm using Google Sheets and Google Collab together and trying to clean up the data I've downloaded as a CSV file. The problem I'm facing is that I want to filter out all results that don't match one of 100+ values one could have as group names which I've grabbed from another spreadsheet and currently have stored in an array. I think there are one or two other filters I'll want to apply, but the others only have four or five possible values in comparison.</p>
