Today Microsoft quietly released an Add-in that allows you to use Word 2010 or Word 2007 as the ultimate Wiki WYSIWYG Editor and it lets you easily convert word documents into Media Wiki format or Wiki style markup. The plugin is a free download from Microsoft Download and installs quickly and easily.
I have a feeling this is going to be a dream come true for those users moving away from Sharepoint and over to MediaWiki. Using this plugin you can now use word as the ultimate WYSIWYG Wiki Editor without knowing a drop of Wiki formatting code. Plus, not only can you create new or convert old standard word docx documents into Wiki Markup, but you can also open pretty much any HTML page in word and re-save it in MediaWiki format. Very cool!
How it works
Download the Word 2007, Word 2010 MediaWiki Add-in and install it. No reboot required however I would close word first.
Simple create your document as normal (or open an existing document / HTML page) and do the typical File –> Save As –> MediaWiki (*.txt)
From there, open your new .txt file and paste the newly converted Wiki Markup into your MediaWiki page. Very quickly and easy!
