Convert SpreadsheetML to binary .xls
 

I have a Excel report that I generated from an .xslt in the
SpreasheetML format but I have to interact with an import routine that
only consumes the binary .xls. Does anyone have any ideas on how to
push this into a binary .xls without having to spawn the Execl app on
the server? I've tried the OWC11 but that only saves as HTML or
SpreadsheetML.

Any help is greatly appreciated!

Thanks,
S
