Sideload Office Add-ins on Mac for testing

  • Article

To see how your add-in will run on Office on Mac, you can sideload your add-in's manifest. This action won't enable you to set breakpoints and debug your add-in's code while it's running, but you can see how it behaves and verify that the UI is usable and rendering appropriately.

Note

To sideload an Outlook add-in, see Sideload Outlook add-ins for testing.

Prerequisites for Office on Mac

  • A Mac running OS X v10.10 "Yosemite" or later with Office on Mac installed.

  • Word on Mac Version 15.18 (160109).

  • Excel on Mac Version 15.19 (160206).

  • PowerPoint on Mac Version 15.24 (160614).

  • The manifest .xml file for the add-in you want to test.
