-APT Photometry data are saved in a table named APT.tbl in the programs root directory. To open this file in Excel, open Excel, navigate to the APT directory, allow all files to show be shown and open APT.tbl.  Excel will allow you to separate the data into cells automatically.  If all data ends up in one column, choose that column and then find the "text to columns" option to separate.
