Is it possible to convert .xmind files to MS Word formats.
Converting XMind Workbook Files directly to Microsoft Office Word formats (.xmind to .doc / .xmind to .docx conversion) should be quite straightforward, since the XMind software allows users to export their .xmind files directly as MS Office formats (Word, Excel, PowerPoint, Project etc.). Some of these features might, however, be only available in XMind's purchased version.
Download XMind for free, and see whether you can accomplish an .xmind to MS Word conversion.
