Description
We needed a JS-first WYSIWYG DOCX editor and couldn't find a solid OSS option, most were either commercial or abandoned.As an experiment, we gave Claude Code the OOXML spec, a concrete editor architecture, and a Playwright-based test suite. The agent iterated in a (Ralph) loop over a few nights and produced a working editor from scratch.Core text editing works today. Tables and images are functional but still incomplete. MIT licensed.

Could you build this?
Partial While an AI can iterate on code, implementing a robust, spec-compliant WYSIWYG editor for the massive and notoriously complex ISO/IEC 29500 (OOXML DOCX) specification requires deep parser engineering and rigorous layout engine work. Vibe coding can produce initial drafts, but handling arbitrary styling, tables, floating elements, and round-tripping DOCX XML without corruption requires extensive manual domain engineering.
What it would actually take: A complete DOCX WYSIWYG editor requires a custom tree/layout rendering engine in TypeScript, coupled with a robust OOXML parser (handling Open Packaging Conventions, drawingML, wordprocessingML namespaces). It necessitates automated visual regression pipelines comparing rendered canvases against native Word outputs across hundreds of real-world sample documents. The core challenge is matching Word's undocumented pagination, layout quirks, and legacy XML schemas.
Discussion
20 comments analyzed.
Competitors mentioned: LibreOffice, Commercial PDF/DOCX libraries, Browser-native document handling
Concerns raised: Complexity of DOCX spec (5000+ pages) makes full compatibility unrealistic, Undocumented Word behaviors deviate from spec, hard to handle, Last 10% of compatibility requires 90% of work, AI-generated imagery with copyright concerns, Replicating existing functionality as SaaS with added costs
Feature requests: Open source web DOCX editing capability, Live debugging and feedback loop visibility, Unit test harness for document generation validation
