Questions for Tristan and Sean

[00:01:45] – Extending Office functionality with Javascript

Office isn’t just an application on Windows that runs on your PC. It is running on iPhone, iPad, Android tablet, and apps on the browser with Office Online. The team needs a new platform, add-ins, which allow you to build apps that run across all places. It’s HTML and Javascript. HTML for all the UI and a series of Javascript module calls for the document properties. Sometimes we call it OfficeJS.

[00:03:20] – This works on any version of Office?

It works on Office on Windows, Mac, Online and iPad.

[00:03:55] – HTML and CSS suck on mobile?

There are things that you’re going to want to do when you know you’re running on a mobile device. If you look at an add-in running on Outlook for iPhone, the developer does a lot of things to make that feel like part of the iPhone UI. Tristan believes that you could build a great add-in for Office using HTML and JavaScript.

[00:05:20] – Are these apps written with JavaScript or you have a Native with WebView?

Office itself is Native. All of it is Native code but the platform is very much web. The main piece of it is pointing at the URL. Just go load that URL. And then, you can also call functions in your JavaScript.

[00:06:35] – Why would you do this? How does it work?

The add-in platform is a way to help developers turn Word, Excel and PowerPoint into the apps that actually solve user’s business problems. The team will give you the tools with HTML and JavaScript to go and pop into the Word UI and the API’s that let you go manipulate the paragraph and texts inside of Word. Or in Excel, you might want to create custom formulas or visualizations. The team also let people use D3 to generate their own Excel charts.

And developers want to extend Office because it’s where a lot of business workers spend their days 0 in Outlook, Teams, Word, Excel.

[00:10:00] – How did this get delivered to them?

There are 2 ways to get this delivered. One, there’s an Office Store. Second, if you go into Word, Excel, and PowerPoint, there’s a store button and you can see tons of integrations with partners.

For enterprises, IT can deploy add-ins to the users’ desktops without having stress about deploying MSI’s and other software deployments that the web completely rids off. The add-ins make a whole lot of pain the past completely go away.

[00:11:00] – Everybody in the company can use a particular plug-in by distributing it with Office?

That’s right. You can go to Office 365 add-in experience. Here’s the add-in and you can to specific people or everyone who’s part of a group.

For the developer’s perspective, if you have the add-in deployed to your client, you could actually push updates to the web service and your users get the updates instantly. It’s a lot faster turn-around model.

[00:14:20] – What about conversations or bot integrations?

There’s the idea of connectors at Teams. You can subscribe to this web book and it’ll publish JSON. When the JSON is received, a new conversation inside of Teams or Outlook will be created. For example, every time someone posts on Stack Overflow with one of the tags that team cares about, it posts on Outlook.

It’s a great way to bring all the stuff. Rather than have 20 different apps that are shooting 20 different sets of notifications, it’s just all conversations in email, making do all the standard email things.

And in the connector case, it’s a push model. The user could ch
