Microsoft Office is a versatile platform in the world of technologies. Not only is it feature-rich, but it is also an expandable platform that caters to a variety of business needs. To power up business operations and efficiency, developers try to extend the functionalities of Microsoft Office for a rich user experience.

Office add-ins are used for extension of functions and alteration of office clients, for example, Microsoft Word, Microsoft Outlook, Microsoft Excel, Microsoft PowerPoint, and Office 365. Microsoft supports the modification of existing features and the creation of new features by using available tools and APIs.

There are different types of Office add-ins - to name a few - functionality extension in PowerPoint, Excel, and Word, creation of new objects in PowerPoint and Excel, extension of functions in Outlook add-ins, etc.

In general, there are two main technologies used for developing Office add-ins:

  • Develop add-in using Office JavaScript API

  • Develop add-in using Visual Studio Tools for Office (VSTO)
