Create an empty Physical File with the name of your choice. Be sure the file record length matches the spool file width. (EX: 80 or 132 or someting else) Once the file has been built use the Command CPYSPLF to populate the Physical File. When copying the spool file specify *NONE for the Key Word CTLCHAR.
When complete you can FTP the file to the desired final destination.
Simplest is just to use iSeries Navigator to list spooled files, drag the desired report to the PC and open it in Excel like any text file.
