Httml2OpenXml is a small .Net library that convert simple or advanced HTML to plain OpenXml components. This program has started in 2009, initially to convert user's comments from SharePoint to Word.
Depends on either the OpenXml SDK 2.0 and .Net 3.5 or OpenXml SDK 2.5 and .Net 4.0.
Looking for .Net core version? Take a look at the dev branch.
Some help in fixing bugs or testing is always welcome :)
