title: Convert Open XML Excel files to HTML
body: <p>I'm developing printing solution for MS Office 2007. Office automation is not right for me, because it requires Office to be installed. <a href="http://openxmlviewer.codeplex.com/" rel="nofollow noreferrer">Open XML Document Viewer</a> is solution for converting Word files (.docx) to HTML format by XSLT transform, but it works only for .docx. Can the same technology be used for Excel spreadsheets files?</p>
