I am using Adobe Acrobat and I purchased the basic version to export pdf to Word. I used this feature and it did convert the document to Word 2003 but the document has errors.
Good to know - export of PDF page content is not "perfect". To optimize a PDF for good export you'd start with a well-formed Tagged PDF (ISO 14289-1, PDF/UA compliant). Once you have the Word file output you would expect to have to do some cleanup in almost all cases.
