Office Web Edition (Clone)

A pixel-faithful office suite in the browser — Office.com-style dashboard plus all four apps: Excel, Word, PowerPoint, OneNote — built from plain HTML/CSS/JS with zero dependencies and zero build tooling, saved into IndexedDB, and guarded by ~1,140 automated end-to-end checks.

Start here

cd /home/user                       # the suite root
python3 -m http.server 8002 --bind 0.0.0.0
# open http://localhost:8002/   → the Office dashboard

The dashboard is the front door: app tiles, Recent documents gathered live from every app's IndexedDB, and one dark-mode switch that syncs into every app (it writes each app's IndexedDB theme key, so every app boots in the same mode).

Port	What	Root
8002	⭐ Office dashboard + all apps under one origin	suite root (/home/user)
8001	Excel alone (test server)	excel/
8003	OneNote alone (test server)	onenote/
8004	Word alone (test server)	word/
8005	PowerPoint alone (test server)	powerpoint/

Serving the suite root is all you need for daily use; the per-app ports exist so each app's tracker battery can point at a stable URL.

The apps

App	Folder	Status
Excel	excel/	Flagship. 265+ formula functions, charts, .xlsx and legacy .xls round-trip (BIFF8 reader + SpreadsheetML-2003 writer), print engine, dark mode — stable
Word	word/	Stable: print-layout pages, styles, footnotes, .docx/.doc import + export, real tab stops, drag & drop, exact-sheet printing, dark mode incl. backstage, IndexedDB
PowerPoint	powerpoint/	Stable: slides, designer, transitions, slideshow, .pptx and legacy .ppt import (slide text from the CFB stream), .pptx round-trip, dark mode, IndexedDB
OneNote	onenote/	Stable: notebooks, ink, tags, search, transcribe, dark mode, IndexedDB (OneNote has no OOXML/legacy open format — Microsoft never defined one — so there is nothing to round-trip; HTML/JSON export provided)

All four apps follow the same house rules and sit behind the dashboard's live tiles.

House rules

1. Zero dependencies, zero build. Open index.html from any static server; there's no npm install for the apps.
2. IndexedDB only. No localStorage anywhere — every app carries a tiny idb.js engine (XKV) that hydrates the store into memory at boot and flushes writes asynchronously. Keys are namespaced: xc.* (Excel), oc.* (OneNote), wc.* (Word), pc.* (PowerPoint).
3. Dark mode everywhere, persisted and dashboard-synced.
4. Trackers or it didn't happen. Behaviors get Playwright batteries that drive the real app through its public namespace (X, ON) and treat any pageerror as failure.
