The common libraries (POI, jExcel) have dependencies on AWT - which doesn't exist on Android; that's why they can't be used.
It's certainly possible in general, as attested by applications like DocumentsToGo.
If you just need to read the format, you might look into what's involved in stripping out all AWT components from those libraries. It's probably a big job, and you'd possibly lose image support, so it'd depend on what you need and how much work you are prepared to do.
