Can I convert Open XML file format to HTML using SDK 2.0?
No. Format conversion (e.g. converting Open XML file format from/to HTML, RTF, WordOpenXML, XML, etc.) is not covered in Open XML SDK 2.0. To solve this problem, we suggest using Word Automation Service, which will allow you to convert Word documents to html on the server, without having Word installed. In the meanwhile Eric White is working on a docx to xhtml transformation built on top of the SDK: blog post link. For more detailed information about file format conversion, please refer to: forum discussion thread 1, forum discussion thread 2 and forum discussion thread 3.
