Microsoft CEO Satya Nadella has previously called Office 365 Microsoft’s “most strategic” API, but it wasn’t until today at Build 2015 that we’re starting to learn more about the company’s plans for Office as a platform.
Specifically, Nadella said that some “fundamental changes” revolving around the user experience are coming to the productivity suite by giving developers the ability to integrate functionality from their third-party apps into the different apps that make up Office. Although the company has offered support for ad-ins for years, this is different in that they’ll live in the cloud, so if you install one add-in it’ll run across the Windows, iOS, and Office Online platforms.
