Create word file with header and footer

Hello friends,
Need one help. In my application; there is one functionality where user can create procedures by writing in CKEditor. User specify number of pages they wanted in the procedure and based on that I provide them that numbers of CKEditor to write procedure per pages. Now, after completing the writing of procedure, they should be able to export the written procedures (which are actually HTML contents written using CKEditor) in word file exactly the same formatting the way it is written in CKEditor with proper header and footer in word.
I tried various ways; like using OpenXML to generate the document but the word file is not generating with proper formatting. Is there any way to generate word file with proper formatting and header footer?
