How can I convert a large number of Word documents to HTML as fast as possible?

I have to convert 500 Microsoft Word 2003 files into HTML documents. What would be the shortest possible way?

I'm not just talking about extension .doc to HTML. I want to convert word files's data into HTML tags.

Word 2007 is installed in my system.

Any suggestion which can help to accomplish this task quickly would be nice.

If you will suggest any tool then that should not be commercial. Should be free or portable.

Solution 1:

I have used this with some pretty good results.

Solution 2:

Google Docs will do it for you :)

Just go to docs.google.com, log in, upload your word file, the go File->Download as->HTML(zipped), and you'll be able to download your word doc in html form inside a zip file.

I'm sure you could automate this with a script somehow, there's an api available. See http://code.google.com/apis/documents/docs/3.0/developers_guide_protocol.html#DownloadingDocs
