# export.toDocx

> Serialize the current document to DOCX bytes under an explicit tracked-change export mode. `review-preserving` (default) keeps open tracked changes as Word revision markup, `final` resolves them as accepted, and `original` resolves them as rejected. Returns the exported bytes plus a structured degradation report of allowed warnings. An invalid mode fails closed with INVALID_INPUT before any work happens.



- Member path: `doc.export.toDocx(…)`
- Mutates document: no
- Idempotency: `idempotent`
- Supports tracked mode: no
- Supports dry run: no

## Expected result

Returns an ExportToDocxResult with the resolved mode, base64 DOCX bytes, byte length, and a report.warnings array.
