Here is something to consider when an application "only spits out Excel": Try opening one of the files with a text editor. You might be surprised that a number of applications actually create CSV, tab delimited or XML files but name them with an XLX or XLXS extension so that Excel will be the default application to open them. That might give you more options to deal with the files.
If you search this forum you'll find folks that are doing that with SAS output creating files in HTML or XML (and other formats) but using file names that end in XLXS to open the results in Excel.
