You could use OpenOffice headless to convert the files from one format to another, say Excel/Doc to TXT/HTML.

We use a similar process combined with ImageMagick to allow people to upload office documents into a presentation app.

Below are a few examples/tutorials on how to achieve this:

Setup OpenOffice

JOD Converter (Java)

PyOD Converter (Python)

If you need any further help with OOo feel free to ask

Good luck :)
