The browser editor
The same DreamSheets editor, running in a browser tab against a cloud document — live co-editing with the desktop app, with deliberate limits.
Documents in DreamSheets Cloud can be opened straight in the browser — no install. It's the same editor the desktop app runs: the same canvas, tables, tiles, charts, formulas, and formula engine, in a tab.
Opening it
- From your drive on the web — open any document there in the browser editor.
- From a share link — a link-shared document opens in the browser for anyone you send it to (they sign in with a free account, and get the role the link grants).
The document you're editing is the cloud copy; every change syncs through DreamSheets Cloud, so there's nothing to save locally and nothing to lose when you close the tab.
Co-editing with the desktop app
The browser tab is a full peer in the document's live session: your edits stream to everyone else who has it open — browser or desktop — and theirs stream to you, in real time, with presence so you can see who else is in the document. Someone with view-only access joins read-only and watches edits apply live.
What needs the desktop app
The browser editor is deliberately a subset. Use the desktop app for:
- Tables over 10,000 rows. The browser receives a bounded window of a big table's rows, so its copy is genuinely partial — and every edit to such a document is refused (a banner explains), so a partial copy can never be written back over the real one. View in the browser; edit on the desktop.
- SQL queries. The browser has no query engine: query tables can't be run or refreshed there, and the Summarize / Combine / Pivot / Unpivot verbs are desktop-only. (Column transforms do work in the browser.)
- Python scripts, plugins, and AI features — all desktop-only.
- Local files. There's no local open or save — the browser editor works purely against the cloud. (File → Import Excel still works: the file uploads to your drive, converts, and opens as a new cloud document.)
None of this cuts the other way: the desktop app works fully offline, and a document edited offline merges back through the normal divergence flow — the browser editor adds a way in, it never takes one away.
