Install the Add-in

2 min read · Updated 23 Sept 2026

Before Excel can talk to Astrato, you need the Add-in. There are two ways to get it — install it yourself, or have your IT team push it to you.

You’ll need:

  • An Astrato account with access to at least one semantic layer. The Add-in doesn’t do anything on its own — it needs your Astrato data behind it. New to Astrato? Say hello at hello@astrato.io.

  • Excel on Windows, Mac, or the web. (On the web, use an up-to-date Microsoft Edge, Google Chrome, or Safari.)

If your organization lets people add their own Office Add-ins, it’s a few clicks:

Step 1: Open Excel.

Step 2: On the Home tab, select Add-ins.

Step 3: Click More Add-ins to open Microsoft Marketplace. Search for Astrato.

Next step: Open Connect to Astrato.

In many organizations, an admin rolls the Add-in out for everyone. If your admin has installed it centrally, the Add-in appears automatically on the Excel Home ribbon — you don’t need to do anything.

If you need to install it as an admin, you deploy it centrally:

  1. Go to the Microsoft 365 admin center.

  2. Open Settings.

  3. Select Integrated apps.

  4. Click Add-ins.

  5. Choose Deploy Add-in.

  6. Pick Astrato from Marketplace, and assign it to Everyone, or to selected users or groups.

Result: the assigned users see the Astrato button on their Excel Home ribbon.

Once it’s installed, an Astrato button appears on the Excel Home ribbon. Click it to open the Astrato panel on the right — that’s where everything happens.
