Real SumDoc and SumSheet, in a browser tab.

Every link on this page opens a real file in a live cabin on this server — no install, no sign-up. Edits live only inside the cabin and are saved nowhere. Open one and count the seconds yourself.

Three things the other office suites don't do

0.11 s vs 5–15 s

Opens a file it has never seen in a fraction of a second. Browser office suites take five to fifteen seconds for the same document. The free tools on sumoffice.com print the real time next to every result — try one.

VBA · Power Query without Excel

Your macros and queries keep working. Workbook_Open, a Worksheet_Change handler, a Power Query over a bank export — they run here, on a Linux server with no Excel on it, and the workbook stays intact. Open the macro or the query workbook below and press Run.

✦ Agent inside the editor

Agents are already in the editor. Press ✦ Agent in any workbook cabin: it reads what the file is made of — macros, queries, connections — proposes the change, and nothing moves until you press Apply. In the desktop apps it is the same panel.

Cabins are shared and anonymous: up to five visitors per exhibit at a time, and a busy exhibit says so instead of queueing you. The same engines ship in the desktop apps, the phone apps and the view-SDK.
