Open-source .docx editor library for building document apps▲107
We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0. A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

Demo video here: https://share.extend.ai/kRmSGKRF When we started, we tried every file viewer and document component library we could find. Unfortunately, none of them had all the functionality (and polish) that we wanted, so we ended up building our own for https://extend.ai/. It was only ever meant to be internal, but enough customers kept asking for it that we decided to…
