ODT to DOCX
Move readable headings, paragraphs, list text, and simple tables from an unencrypted ODT into a clean, separately generated DOCX package.
Processed in this browserOne unencrypted .odt file up to 10 MB, 1,000 package parts, and 80 MB expanded data. The output contains bounded text and simple tables only.
ODT - 10 MB - clean DOCX
No file upload
This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.
Original stays unchanged
The converter creates a separately named output. It never writes back into the source file.
Bounded work
One unencrypted .odt file up to 10 MB, 1,000 package parts, and 80 MB expanded data. The output contains bounded text and simple tables only.
Plain-language method
How ODT to DOCX works
Nirmion checks the ODT archive before decompression, reads office:text from content.xml, keeps document order, maps heading levels, paragraphs, list items, and simple table cells, then builds a standards-based OOXML Word package.
- 01Choose a valid source
Use an unencrypted text ODT containing ordinary body content. Embedded scripts are never executed and external resources are not loaded.
- 02Review the conversion choices
There are no conversion choices because the safe mapping is fixed. Clean up advanced layout in LibreOffice before conversion when appearance matters.
- 03Inspect the separate result
The result ends in _nirmion_tools.docx. It is a new editable document with basic structure, not a byte-for-byte or style-perfect copy.
Useful when
Practical jobs this tool handles
- Move a simple ODT draft into a Word workflow.
- Recover editable text and tables from an open format.
- Create a clean DOCX base for manual restyling.
Before converting
Check the source and destination rules
- Check heading hierarchy and list markers.
- Review merged or complex tables manually.
- Reinsert required images, footnotes, fields, and page styling.
Know the boundary
Know what the destination format cannot keep
Images, drawings, comments, tracked changes, footnotes, automatic numbering, page styles, columns, fields, formulas, embedded objects, and complex table merges are not preserved in this focused release.
Quick answers
Questions before you convert
The conversion contract is deliberately explicit.
Is the original styling preserved?
No. The converter prioritises readable structure and predictable DOCX output.
Will images be copied?
No. Add required images again in an authorised document editor.
Can I edit the result?
Yes. The output is a real DOCX package containing ordinary Word paragraphs and tables.
