FAQ and format details
Why convert Word to OpenDocument?
A contractor delivers DOCX; the records schedule says ODT. Or your team standardizes on LibreOffice and you are tired of import warnings. Going through a semantic HTML hub drops Word-only features explicitly instead of half-translating them.
How this conversion runs
Mammoth → HTML blocks → content.xml headings, paragraphs, lists, and tables, plus Strong/Emphasis styles. The ZIP is a minimal ODT, not a clone of Word's theme. Images as data URLs can embed; floating Word art usually will not.
Keep in mind for Word → OpenDocument
You will lose VBA, content controls, and some table looks. Track Changes should be resolved in Word first. Writer will not magically gain your corporate Heading 1 color. For an official PDF from an office suite, export from Writer after this step.
After you have a OpenDocument file
Open in LibreOffice and run a style cleanup. If Google Docs is the next stop, it can import ODT. Keep the DOCX only if you still need Word comments.
Is this better than LibreOffice opening the DOCX?
Different. Writer's filter knows more Word oddities; this path is more predictable and drops what the HTML hub cannot see. Compare both on a sample if the document is legally sensitive.
Do macros convert?
No, and .docm is not accepted. That is intentional.

About Microsoft Word (Office Open XML) and OpenDocument Text
Source file
Microsoft Word (Office Open XML)
The default Word format since 2007: a ZIP package of XML parts for body text, styles, media, and document settings.
DOCX (Office Open XML WordprocessingML) replaced the binary .doc format. It is the interchange format for business documents: resumes, contracts, manuscripts. Word, Google Docs, LibreOffice, Pages, and OnlyOffice all read and write it. Macros live in a sibling .docm type, which this converter does not execute or emit.

Catalog notes
Destination file
OpenDocument Text
The ISO text format used by LibreOffice Writer and OpenOffice: a ZIP of XML, the open counterpart to DOCX.
ODT is part of the OpenDocument family (ODS spreadsheets, ODP presentations). Governments and open-source shops standardize on it. Internally it is content.xml plus styles, metadata, and media. Conversion through HTML maps text:h / text:p / tables onto HTML equivalents.
