Converters to Wikitext

 * Mediawiki editing tools
 * Excel-to-Wiki Converter -- a nice online converter
 * HTML::Wiki Converter -- a nice online converter (unfortunately, now abandoned)
 * http://bmanolov.free.fr/html2wiki-tables.php#wiki - seems to work quite well
 * http://openfacts2.berlios.de/html2wiki/
 * HTML Tags Stripper is designed to strip HTML tags from the text. It will also strip embedded JavaScript code, style information (style sheets), as well as code inside php/asp tags ( <%php ?> <% %>)

 * Also, see Word2MediaWikiPlus, an extension to Word, that is promising, but not yet ready for primetime.

PHP

 * Perhaps the best choice from a PHP developers point of view is the Text_Wiki PEAR Package. It "transforms Wiki and BBCode markup into XHTML, LaTeX or plain text markup." It has even a adapter for Mediawiki code
 * PHP: http://www.ffnn.nl/pages/projects/wiki-text-to-html.php

Others
