I created an .xls spool file, as an output from an SQL script.

This .xls spool file is the source file for a report in xls. I would like to automatically update the xls report - when opening - with the new data from the xls spool file. However, this can only be done if I also open the source file. And that's exactly what I don't want. I only want to see the report xls file. Does anyone know how tho do this?
