Notes on this conversion
This is the reverse of the DOC to DOCX route and exists for one reason: a reader that predates Office Open XML, or never learned it. The pair is published as deterministic and the conversion-loss table records no entry for it, so the result is an ordinary Word 97-2003 document rather than an approximation of one. It is a compatibility move rather than an upgrade — the .docx stays the copy worth keeping, and converting back is worthwhile only for the reader that made the trip necessary.

Frequently Asked Questions
Why convert to the older format at all?
For a reader that predates Office Open XML, or one that only ever learned the binary format. It is a compatibility move, not an upgrade, and the .docx is the copy worth keeping.
Is anything lost going backwards?
This pair is published as deterministic and the conversion-loss table records no entry for it, the same as the forward direction.
Can the result be edited normally?
Yes. The output is an ordinary Word 97-2003 document, editable in Word, LibreOffice Writer and anything else that reads the binary format.
