I am trying to import data from a few Spreadsheets using IMPORTRANGE(), however having every spreadsheet_key inline would make it a pain to read, a pain to add a new key. I am trying to load the spreadsheet_keys from a list, something like:
=IMPORTRANGE({Settings!A30:A31}, "Test!A2:V")
where Settings!A30 holds a key and Settings!A31 holds a second key.
I don't get any errors, but it only loads data from the first spreadsheet!
Is there a way to get this working?
