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.

01
Choose a valid source
Use an unencrypted text ODT containing ordinary body content. Embedded scripts are never executed and external resources are not loaded.
02
Review 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.
03
Inspect 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.
