DOCX at a glance
DOCX
Convert to DOCX when the document will keep evolving after export.
It is the right target for contracts under review, proposals with tracked changes, policy drafts, editable reports, and documents that recipients are expected to open in Word or Word-compatible editors.
Choose DOCX when comments, revision history, page layout, headers, footers, and embedded assets need to remain editable.
If the goal is fixed presentation or print fidelity, PDF is usually better; DOCX is for collaborative editing and office workflow compatibility.
DOCM at a glance
DOCM
Convert to DOCM when the output must retain or deliver Word macro functionality, such as automated forms, button-driven templates, mail-merge helpers, or internal workflow documents with embedded VBA.
It is appropriate only when the recipient environment expects macro-enabled Word files and can handle the associated trust model.
If macros are not needed, DOCX is the safer and more portable choice.
