What you get

Live-synced models

Open .deepcell files directly in Excel. Changes sync back to your workspace automatically.

Cell metadata

See formulas, data sources, and dependency chains for every cell right in the sidebar.

Secure auth

Sign in with your DeepCell account. OAuth 2.1 + PKCE keeps credentials safe — no secrets stored in Excel.

Conflict resolution

Color-coded cells highlight conflicts when multiple editors touch the same model.

Install the add-in

Run a single command to install, or follow the manual steps for your platform.

Automatic installation (recommended)

Open PowerShell and paste the command below. It registers the DeepCell server as a Trusted Add-in Catalog in Excel automatically.

Copy and paste into your terminal:

irm https://beta.deepcell.net/excel-addin/install-addin.ps1 | iex
Manual installation steps
1

Add a Trusted Add-in Catalog

Open Excel, then go to File > Options > Trust Center > Trust Center Settings > Trusted Add-in Catalogs.

In the Catalog URL field, enter https://beta.deepcell.net/excel-addin. Check "Show in Menu" and click OK. Restart Excel.

2

Insert the add-in

In Excel, go to Insert > My Add-ins > Shared Folder. Select DeepCell and click Add.

Get started

1

Open DeepCell in Excel

Click the DeepCell tab in the ribbon, then Open DeepCell. The task pane opens on the right side.

2

Sign in

Enter your DeepCell credentials. The add-in authenticates via OAuth — your password is never stored locally.

3

Open a file

Browse your workspace, pick a .deepcell file, and it loads into the active sheet. Edits sync back when you commit.

Troubleshooting

Blank white panel after opening

This usually means Excel cannot reach the add-in server. Check that https://beta.deepcell.net/excel-addin/taskpane.html loads in your browser. If your network blocks the domain, contact your IT team.

"My Add-ins" option is missing

This option requires a Microsoft 365 subscription (Business or Enterprise) or Excel 2016+. On the web, look under Insert > Office Add-ins.

Sync failures or stale data

Ensure you are signed in and your session has not expired. Click Refresh in the task pane. If the problem persists, close and reopen the task pane.
