Why convert DOCX to ODT?

  • Escape vendor lock-in for long-term archives; the full ODT specification is public, so future software can always read it.
  • Work day-to-day in LibreOffice or Collabora Online without conversion warnings on every save.
  • Prepare grant and tender paperwork for portals that validate uploads against open formats.

Tip: Numbering, tracked changes, and text-box anchoring are the usual friction points between Word and Writer - proofread those areas in anything contract-grade.
