OOXML Office
Every app in one workspace, with a shared file library, tabs, search and an assistant. Installs as an app and runs offline.
Documentation
OOXML Office is a set of Office editors that run in the browser: Word, Excel, PowerPoint and Visio files, plus a team workspace. There are three ways in. Use the apps as they are, embed one editor in your own site, or build on the library underneath them.
Word Beta
Write and format documents with a ribbon, print layout, tracked changes and comments.
Excel Beta
Workbooks with formulas, charts, conditional formats, sorting and filtering.
PowerPoint
View, edit and present slide decks, and work on one deck together.
Visio Alpha
Open diagrams and flowcharts: pages, shapes, connectors and text.
Teams Alpha
Channels, chat, presence and calls on a server you run, with Office files in the conversation.
Word editor
The <docx-editor> element. Install the package for your framework;
it brings the editor and the document model with it.
Excel editor
The <xlsx-editor> element, with the same six framework packages.
PowerPoint viewer and editor
Rendering, editing, presenting and collaboration for React, Vue, Angular, Svelte and plain JavaScript.
Visio viewer
The <visio-viewer> element: local-first, six framework packages.
Team workspace
The <teams-app> element, framework packages with raw hooks, and a
small reference server.
Shared UI elements
The ribbons, menus, dialogs and status bars every editor is built from, published as
ooxml-ui, themeable through one set of tokens.
ooxml-core
Parse, edit, validate and write every Office format with no UI: documents, workbooks, decks and diagrams, charts, SmartArt, maths, encryption and collaboration.
Agents and automation
One Model Context Protocol server for every format, so an agent can read, create and change files, plus the headless operations it runs on.
Legacy formats
The sibling package reads .doc, .xls and .ppt and the compound-file container; the editors inline it, so legacy files open without an extra install.
Repository and roadmap
One monorepo holds every package and app. The roadmap lists what each app still lacks against the Office applications and in which order it is planned.
Contributing and releases
Commit conventions, the checks that run before a push, and how a change becomes a release. Every package is versioned from its commits and published with provenance.
Questions, bugs and licence
Discussions for questions and ideas, issues for bugs and requests. Everything is Apache-2.0.
