You may want to edit the transferred data. Transferred sheets should not directly be edited because any edits are being deleted the next time the connection is run.
We recommend you create a separate sheet next to the transferred sheet and then use the =ARRAYFORMULA to bring over the data you need from the destination sheet to this helper sheet.
Imagine you used the ARRAYFORMULA to bring over columns A,B,C. Then you can do edits in column D onwards without breaking the sheet.
