if you are thinking of running Word or Excel on the server to do some automation: don't. It's not licensed for that, and won't work properly anyway.
But Word and Excel documents are just fancy zipped xml documents, so with the right set of libraries you can create them, poke values into them, etc. I'm sure you can find some commercial libraries online.
Not sure how your question pertains to the MSFT Access database product, the topic of this forum.
