Convert legacy StarOffice Writer SXW documents into modern Microsoft Word DOCX format instantly. This tool is essential for anyone needing to open older office files in contemporary software.

The SXW format is the native text document standard used by older versions of StarOffice Writer, whereas DOCX is the standard XML-based document format for Microsoft Word and modern office suites. When you convert SXW to DOCX, the underlying file architecture is updated from older OpenOffice structures to the modern compressed XML standard used by Word, allowing your document to be easily edited and shared today.

The conversion between SXW and DOCX is executed without data loss, preserving your original text formatting, tables, and layout completely intact.

Tips

Ensure your SXW file is not password-protected before uploading for conversion.
Check complex embedded objects in the resulting DOCX to confirm compatibility with your version of Word.
Keep a backup copy of your original SXW file for archival purposes.

Common use cases

Opening legacy StarOffice archives in current Microsoft Office applications.
