About the Book

This book is about creating Office Add-ins – and in particular, about the Office 2016+ wave of Office.js APIs.

Want to get started with just the very core concepts, before buying the book? Download some sample chapters, or better yet, buy the book regardless: I am sure you'll find the topics therein new and useful for writing add-ins; and if you don't, LeanPub's Happiness Guarantee will let you get a full refund anytime in the first 45 days.

Office 2016 has seen a major re-birth of the API model, with hundreds of new APIs created for Excel and Word and OneNote. These APIs are cross-platform, are built on a modern web framework, and offer some of the same powerful functionality that previously was only available on the Desktop.

In spirit, the new Office.js APIs are reasonably similar to their VBA/VSTO counterparts, but with the notable difference of being async – which brings with it a new set of concepts and best practices. This book will begin by address the core concepts to help you get over the initial learning curve, and get started on using the APIs. The subsequent chapters will expand upon these topics, covering more advanced scenarios, and offering debugging advice, tips, FAQs, and so forth.

@BuildingAddins

This book is written for Office Developers, by an Office Developer. By the latter, I mean both that I had been a developer who used Office technology extensively for a number of years, and that I am now a developer on the Office Extensibility Platform team – the very team that created Office Add-ins.

Having been a key participant in the design of the new Office 2016 wave of Office.js APIs – and having seen folks embrace the framework, but struggle with some of the more concepts – I wanted to share some insights & techniques, as well as the full end-to-end story, of how to create Office Add-ins.

You can find me on StackOverflow, where I frequently answer questions tagged as "[office-js]" (which has been a source of inspiration for many sections of this book).  I have a backlog of topics I want to cover in this book: some already fleshed out, others less so.  In the spirit of the "lean" methodology, I will be updating the book frequently as I cover more and more topics.  Thanks for reading, and please feel free to contact me for feedback on the book, requests for topics, etc.

Yours truly,
