this doesn't seem to be an excel problem, but rather a target problem
you seem to have a launch page that specifies the output of your fex to be in an iframe.
so, regardless of the output format (just a variable to the fex), the report is going to come out in that iframe. Try it with PDF to see what i mean.
so... without a load of agita...
i no longer put output options into launch pages, not when i'm using iframes or frameset frames.
instead, i put icons in the report heading
an Icon for excel(that nice green x), an icon for pdf (a nice red one), a pushpin for frozen column titles, and that blue A for active reports ...
Each of these icons has a link under it, just like any other drilldown.
and in the style sheet
TYPE=HEADING,LINE=1,ITEM=1,TARGET=BLANK,FOCEXEC=thesameone(&WFFMT=EXL2K),$
TYPE=HEADING,LINE=1,ITEM=2,TARGET=BLANK,FOCEXEC=thesameone(&WFFMT=PDF),$
