Office Add-in host and platform availability

To work as expected, your Office Add-in might depend on a specific Office host, a requirement set, an API member, or a version of the API. The following tables contain the available platforms, extension points, API requirement sets, and Common APIs that are currently supported for each Office application.

Note

The initial Office 2016 release installed via MSI only contains the ExcelApi 1.1, WordApi 1.1, and Common API requirement sets. For more information about the update history of the various Office versions, check out the See also section.
