The site www.infpro.com provides a Word2MediaWiki.bas Makro, as well as a description.

The Word2MediaWiki makro doesn’t work in German Microsoft Word installations. For my german friends: At my site, you can download the english version, or the german version.

2. start Word
3. press ALT-F11
4. import the macro to “Normal” (right click).

1. press ALT-F8 and start the function
2. copy the text and insert it to the Wiki or to notepad

And the same in german / Und auf deutsch:

4. Makro in “Normal” importieren (Rechtsklick).

1. ALT-F8 drücken und starten
