I followed these instructions, but I do not seem to get an editable file. I get the message "You may download test or create a linked copy to the worksheet or delete test. Access test in this worksheet by typing DATA+'test'. Here DATA is a special variable that gives the exact path to all data files uploaded to this worksheet.
