Exquisite formatting

Preserve your DOCX on import and export

SuperDoc doesn't alter the structure of the original document - we open the DOCX in your application- rather than converting to HTML then back again to deliver a closer to Word like experience on the web. This lets your users take advantage of advanced formatting and for you to turn their document complexity into a competitive advantage..
