Faithful render
Word-grade document structure

Tables, numbering, footnotes, headers, styles, and tracked changes stay document-native.

Surgical edit
Edit without flattening

Formatting and text edits flow back into OOXML—not a canvas, screenshot, or lossy HTML export.

Private by design
Save locally as .docx

The source document and every edit remain in your browser session.

Not a screenshot

The document below is live.

This is the shipped editor surface — the same ribbon, tables, footnotes and header/footer tools you get from createRibbonEditor in the npm package. It narrows to a one-handed layout on a phone. Open it full screen ↗ · Play the arcade on it ↗

Not a video

The game below is a Word document.

Its screen is one paragraph, rewritten and re-rendered ten times a second by the same engine that edits contracts — on the same shipped ribbon. Pause and type terrain straight into the level; resume and it is solid. Save mid-jump and you get a real .docx. Open it full screen ↗ · Prefer the plain editor? ↗

Two ways to ship it

Put Docxodus anywhere.

Use the compact hosted player for a zero-build embed, or import the editor module when you want the full surface inside your own product.

Drop-in iframe · compact player

Boots on tap and fits a small panel. Good for a sidebar or a card in a feed.

Native JavaScript · the full ribbon surface

One call mounts the entire editor — ribbon, tables, notes, header/footer bands and the loading overlay — and it picks its own layout from the width of the element you give it.
