Install (2 minutes)
🌐 Excel on the web — easiest
- Download the add-in file (ToolBelt-manifest.xml).
- Open any workbook at excel.cloud.microsoft.
- Go to Home → Add-ins → More Add-ins (on some ribbons: Insert → Add-ins).
- Choose the MY ADD-INS tab → Upload My Add-in → select the downloaded file.
- ToolBelt appears on your ribbon. Select a range and click a fix.
🖥️ Excel on Windows desktop
- Download the installer script (install-windows.ps1).
- Right-click the downloaded file → Run with PowerShell. Approve the admin prompt (it registers a local trusted add-in folder — a one-time Windows requirement for add-ins installed outside the Office Store).
- Restart Excel, then go to Insert → Get Add-ins (or Home → Add-ins → More Add-ins) → SHARED FOLDER tab → ToolBelt for Excel → Add.
Prefer to see what the script does first? It's ~40 readable lines — open it in Notepad. To uninstall, run it again with -Uninstall.
🍎 Excel on Mac
- Download the add-in file.
- Open Terminal and paste:
mkdir -p ~/Library/Containers/com.microsoft.Excel/Data/Documents/wef cp ~/Downloads/ToolBelt-manifest.xml ~/Library/Containers/com.microsoft.Excel/Data/Documents/wef/
