Features & use cases

Features

  • Word DOCX is opened by LibreOffice headless and exported as OpenDocument Text, prioritizing office fidelity for docx-to-odt.
  • Paragraph styles, tables, images, headers, footers, and page breaks are preserved when LibreOffice can map them.
  • Macros, scripts, document automation, and active form behaviour are not executed or preserved in the output.
  • Missing fonts are substituted by server fonts, so line breaks and pagination can shift from the authoring machine.

Use cases

  • Prepare DOCX files for tools that expect ODT.
  • Create reviewable samples for support tickets, tests, and data handoffs.
  • Batch recurring file chores while keeping warnings attached to each output.
  • Normalize partner or archive files without installing desktop conversion software.

What actually changes

Word DOCX is opened by LibreOffice headless and exported as OpenDocument Text, prioritizing office fidelity for docx-to-odt.
Paragraph styles, tables, images, headers, footers, and page breaks are preserved when LibreOffice can map them.
Macros, scripts, document automation, and active form behaviour are not executed or preserved in the output.
Missing fonts are substituted by server fonts, so line breaks and pagination can shift from the authoring machine.
Tracked changes are accepted as the visible document state; reviewer comments may not appear unless they are visible in the exported view.
The destination office file is editable but may not keep application-specific templates, themes, or unsupported controls exactly.

Options

LibreOffice export filter

Override the LibreOffice convert-to filter string when an advanced workflow needs a specific export filter.

FAQ

Will OpenDocument Text look exactly like my Word DOCX?

LibreOffice preserves common office layout well, but missing fonts, app-specific effects, and unsupported features can change the result.

What happens to macros?

Macros and scripts are not run and are not preserved as working automation in the converted output.

Are tracked changes and comments kept?

Tracked changes are exported as the accepted visible state. Comments may be omitted unless the office view renders them into the document.

Does spreadsheet to PDF keep pagination?

This pair is not a spreadsheet-to-PDF export.

Can I request PDF/A?

Not with the currently honoured options. The service exposes LibreOffice's filter override but no dedicated PDF/A toggle.

Everything you need

Browser-first privacy

CSV, JSON, XML, YAML, XLSX, and table conversions run locally when the source and target formats support it.

Warnings, not surprises

Formula drops, flattened arrays, sheet selection, and layout changes are surfaced as conversion warnings.

Batch and zip

Queue multiple files, download individual results, or package them into a zip for handoff.

API, CLI, MCP

Convert from browsers, scripts, automations, and AI assistants with the same warnings and outputs.

Team workspaces

Shared history, API keys, limits, and retention settings keep production conversions controlled.

Retention you control

Browser files never upload; server inputs auto-delete within 24 hours and outputs follow workspace retention.
