This add in gives the ability to embed a Tableau Viz inside of a PowerPoint document. Currently, the add-in is not published to the Office Store, but you can still try it out locally. The html and javsacript for the add-in is hosted from this Github Repository via GitHub pages. The main page is located here (it won't do anything outside of PowerPoint).
If you are a SharePoint Administrator, you can add the add-in to your organization's list of add-ins (See here). This will give the best experience since the add-in should work across all platforms.
The add-in is defined by its manifest XML. This is located in the project at ./dist/office/tableau-manifest.xml. This is the manifest you'll need to use this add-in
To set up the add-in in Windows, you'll need to configure a shared folder which contains the manifest XML. You'll then need to edit some settings in PowerPoint to make this folder as trusted add-in catalog. For simplicity, you can use the shared folder \\tsi.lan\files\Home\AMER\sdesmond\Shared\tableau-ppt. See the full instructions here.
On Mac, you simply need to place the manifest XML in a particular location. See full instructions [here] (https://dev.office.com/docs/add-ins/testing/sideload-an-office-add-in-on-ipad-and-mac).
For Office Online, you need to upload the manifest XML. See full instructions here.
Please Note: The only way for the seamless use of an add-in between Windows, Mac, and Online is if the add-in is published to a SharePoint catalog or in the Office Store.
It's written in react. Try the usual npm install and npm start. More details to come soon...
