Install the Excel or PowerPoint add-in

Last updated November 10, 2026

The SankeyArt add-in lets you create Sankey diagrams directly in Excel and PowerPoint. It's one add-in for both: once it's installed, you'll find it in both applications.

This is the recommended way.

  1. Open the SankeyArt add-in on Microsoft's Marketplace.
  2. Select Get it now.
  3. Follow the steps. They open Excel or PowerPoint and finish the installation there.

You can also install it from inside Excel or PowerPoint:

  1. Select the Add-ins button.
  2. Search for "SankeyArt".
  3. Select the add-in and install it.

Use this if your organization restricts access to Microsoft's Marketplace, or for testing.

  1. Download the SankeyArt add-in manifest file.
  2. Upload it in Excel or PowerPoint: - Windows: select File > Get Add-ins, go to My Add-ins, select Manage My Add-in and then Upload, and choose the file. - Office on the web: select Home > Add-ins > More Settings. In Office Add-ins, select Upload My Add-in, browse to the file and select Upload. The browser keeps the add-in, so upload it again after clearing your browser data or in another browser. - Mac: copy the file into ~/Library/Containers/com.microsoft.Excel/Data/Documents/wef (for PowerPoint, com.microsoft.Powerpoint), restart the app and find SankeyArt under Home > Add-ins.

If your organization blocks the Office Store, uploading may not be possible. Ask your IT team to deploy the add-in instead.

To install the add-in for everyone in your organization at once, see Deploy the add-in for your organization.

After the installation, you'll find SankeyArt on the Home tab under Add-ins, or on the Insert tab.

Open the add-in and sign in with the same account you use at sankeyart.com. Select Continue with Microsoft, Continue with Google or Continue with email. If you don't have an account yet, you can sign up the same way.

Not signed in yet? Select Try our demo diagram to try the editor first.

Once you're signed in, the add-in shows what you can do next:

The add-in stores your diagrams in the SankeyArt cloud, just like the web app. Any diagram you create or edit in the add-in is in the web app at sankeyart.com too, and the other way round.
