Insert and update diagrams in PowerPoint

Last updated November 10, 2026

With the SankeyArt add-in for PowerPoint, the diagram lives on the slide itself. You edit it right there, and it stays the same diagram as in the web app and in Excel.

You need the add-in installed and to be signed in. See Install the Excel or PowerPoint add-in.

  1. Go to the slide where you want the diagram.
  2. On the Insert tab or the Home tab, select Add-ins and then SankeyArt.
  3. The add-in appears on the slide. Move and resize it like any other object.
  4. Choose a diagram: - Create from template starts a new diagram. See Start from a template. - Saved diagrams opens one you made before, in the web app, in Excel or in PowerPoint.

To show another diagram, insert the add-in again, on the same slide or another one. Each one keeps its own diagram.

Edit the diagram in the add-in the same way as in the web app: change the data in the Data editor, and the labels, colors and layout in the menus. Your changes are saved to your SankeyArt account.

If the diagram was created from Excel data, you can't edit its data in PowerPoint. Change the cells in your spreadsheet instead, see Create a diagram from Excel data.

When you're done editing, select Present. The add-in then shows only the diagram, without the editor around it. The shortcut is Ctrl+Alt+P on Windows and ⌥⌘P on a Mac. Press Esc, or select the close button in the top right corner, to go back to the editor.

The add-in opens with the view you left it in, also in a slide show. Select Present before you save the presentation, so the slide shows only the diagram.

The add-in stores your diagrams in the SankeyArt cloud. A diagram on a slide is the same diagram as in the web app and in Excel, so your changes there show up in PowerPoint too.

The add-in loads the latest version of the diagram when the presentation opens.

If you need a static picture instead, for example for a PDF or another tool, download the diagram as an image. See Export as PNG or SVG.

Billing admins don't use a seat, so they can't insert or edit diagrams. See Roles and permissions.
