GREEN INSTALL · NO .EXE

Office, by hand

Sumlion is an Office add-in described by one small XML file, the manifest. Upload it inside Excel (or Word) once and the pane is registered for your account. No administrator rights, nothing written to the registry.

About 2 minutes

Don't see “Upload My Add-in”?

Some perpetual builds (Office 2021 / 2024) hide it. Use a trusted folder instead — still no .exe:

Create a folder, e.g. C:\Sumlion, and put the manifest file(s) in it.
Share the folder with yourself: right-click → Properties → Sharing → Share… → add your own user → Share. Note the network path shown (\\YOUR-PC\Sumlion).
In Excel: File → Options → Trust Center → Trust Center Settings → Trusted Add-in Catalogs. Paste the network path into Catalog Url, click Add catalog, tick Show in Menu, OK. Restart Excel.
Insert → My Add-ins → SHARED FOLDER tab → Sumlion → Add.

Done

The pane updates itself from app.sumlion.cn. To remove Sumlion: Insert → My Add-ins → right-click Sumlion → Remove.
