@M.Cihad Tavacioglu I tried to "Make a Copy" and it's still on "View Only" ... I tried importing, it didn't work. Error says, "Too large to import. Remove rows or columns and try again." Copy pasting from Excel to Google Sheet wouldn't work as well because of too large amount of data. I tried downloading to CSV too and it gives the same error "Too large to import. Remove rows or columns and try again."
