*[[http://w-i-k-i.appspot.com/]] works but not specifically to pmwiki syntax   [[html-wiki test]]  using w-i-k-i.appspot.com
*[[http://openfacts2.berlios.de/html2wiki/index.php]] specifically converts to pmwiki syntax  [[html2wiki test]]
* Just paste the html into an edit box..   cookbook parser will work (it is installed).  Similar results to [[html2wiki test]].

The last two handle more of the actual html code which needs to be removed, but they do things like draw boxes which the appspot cannot do because it is not producing pmwiki code.
