DOC is Microsoft's proprietary binary word processing format, tied to the Windows ecosystem and the OLE2 compound document specification. ODT (OpenDocument Text) is an open ISO standard (ISO 26300) for word processing documents, used natively by LibreOffice, Apache OpenOffice, and other open-source office suites. Converting DOC to ODT moves your documents from a closed proprietary format to an open standard backed by international standardization.

The conversion maps DOC's binary formatting records to ODT's XML-based structure. ODT uses the ODF (Open Document Format) packaging convention — a ZIP archive containing content.xml (body text), styles.xml (formatting), meta.xml (metadata), and media files. The result is a fully editable document that works in any ODF-compliant editor without requiring Microsoft Office.

Several governments — including those of France, Italy, Brazil, India, and the UK — mandate or recommend ODT for official documents to avoid vendor lock-in to Microsoft. If you submit documents to public sector organizations in these countries, ODT may be required rather than optional. Converting DOC to ODT ensures compliance with these open-format mandates.

ODT is also the native format for LibreOffice, the most widely installed free office suite with over 200 million downloads. If your team uses LibreOffice, working in ODT avoids the compatibility layer that LibreOffice applies when reading DOC files. Opening DOC in LibreOffice sometimes introduces formatting inconsistencies because LibreOffice must reverse-engineer the proprietary binary layout. Working in ODT natively eliminates this translation step.

LibreOffice reads the DOC binary using its Word import filter, parsing OLE2 streams to extract text, formatting, embedded objects, and document properties. The document model is then serialized as ODF 1.2 XML — paragraphs become <text:p>, headings become <text:h>, tables become <table:table>, and character formatting is expressed as ODF style attributes. Embedded images are stored in the Pictures/ directory within the ZIP archive. Page layout properties (margins, orientation, headers, footers) are mapped to ODF page styles. The conversion handles style inheritance, list numbering continuations, and section breaks.

Standard formatting — fonts, styles, tables, images, lists, headers, footers — converts accurately. Complex features like embedded OLE objects, advanced field codes, and some drawing primitives may not transfer perfectly.

Yes. Microsoft Word has supported ODT import since Office 2007 SP2. However, some ODT features may render slightly differently in Word compared to LibreOffice.

To avoid vendor lock-in and ensure public documents remain accessible regardless of any single company's product decisions. ODT is an ISO standard, ensuring documents can be read by any compliant software.

No. DOC VBA macros cannot be converted to ODT's macro format (which uses StarBasic or Python). Macros must be rewritten for the target platform.

Yes. LibreOffice Viewer, Collabora Office, and several other apps read ODT on Android and iOS. Google Docs on mobile also imports ODT files.
