Prerequisites for developing add-ins for Office

The recommended IDE for add-ins development is Visual Studio 2015. There is a free version for individual developers and open source contributors (Visual Studio Community Edition) that can be downloaded from https://www.visualstudio.com/en-us/ products/visual-studio-community-vs.aspx

Download and install the Office Developer Tools extension for Visual Studio from https://www.visualstudio. com/enus/features/officetoolsvs.aspx

Last of all, but most important, you will need Microsoft Office 2013, 2016 or Office 365. If you don’t already have one of these, you can download a trial version from the Office website or sign up for the Office 365 Dev program ( http://dev.office.com/devprogram).

Tip: Alternatively, Napa Development Tools can also be used for Office development. Napa is a free, quick, in-browser tool for developing Office add-ins. Napa tools can be accessed from the website https://www.
