Build your first PowerPoint task pane add-in
In this article, you'll walk through the process of building a PowerPoint task pane add-in.
Create the add-in
You can create an Office Add-in by using the Yeoman generator for Office Add-ins or Visual Studio. The Yeoman generator creates a Node.js project that can be managed with Visual Studio Code or any other editor, whereas Visual Studio creates a Visual Studio solution. Select the tab for the one you'd like to use and then follow the instructions to create your add-in and test it locally.
Node.js (version 8.0.0 or later)
npm install -g yo generator-office
Even if you've previously installed the Yeoman generator, we recommend you update your package to the latest version from npm.
Create the add-in project
Spaces are not currently permitted in the add-in project name or anywhere in the folder path where you create your add-in project. If your add-in's project name or folder path contains spaces, the local web server won't start when you run
npm start or
npm run start:web. This limitation is temporary and will be eliminated when the underlying issue is resolved in the Yeoman generator for Office Add-ins.
Use the Yeoman generator to create a PowerPoint add-in project. Run the following command and then answer the prompts as follows:
- Choose a project type:
Office Add-in Task Pane project
- Choose a script type:
- What do you want to name your add-in?
- Which Office client application would you like to support?
After you complete the wizard, the generator creates the project and installs supporting Node components.
Explore the project
The add-in project that you've created with the Yeoman generator contains sample code for a very basic task pane add-in. If you'd like to explore the components of your add-in project, open the project in your code editor and review the files listed below. When you're ready to try out your add-in, proceed to the next section.
- The ./manifest.xml file in the root directory of the project defines the settings and capabilities of the add-in.
- The ./src/taskpane/taskpane.html file contains the HTML markup for the task pane.
- The ./src/taskpane/taskpane.css file contains the CSS that's applied to content in the task pane.
Try it out
Navigate to the root folder of the project.
Complete the following steps to start the local web server and sideload your add-in.
Office Add-ins should use HTTPS, not HTTP, even when you are developing. If you are prompted to install a certificate after you run one of the following commands, accept the prompt to install the certificate that the Yeoman generator provides.
If you're testing your add-in on Mac, run the following command before proceeding. When you run this command, the local web server starts.
npm run dev-server
To test your add-in in PowerPoint, run the following command in the root directory of your project. This starts the local web server (if it's not already running) and opens PowerPoint with your add-in loaded.
To test your add-in in PowerPoint on a browser, run the following command in the root directory of your project. When you run this command, the local web server will start (if it's not already running).
npm run start:web
To use your add-in, open a new document in PowerPoint on the web and then sideload your add-in by following the instructions in Sideload Office Add-ins in Office on the web.
In PowerPoint, insert a new blank slide, choose the Home tab, and then choose the Show Taskpane button in the ribbon to open the add-in task pane.
At the bottom of the task pane, choose the Run link to insert the text "Hello World" into the current slide.
Congratulations, you've successfully created a PowerPoint task pane add-in! Next, learn more about the capabilities of a PowerPoint add-in and build a more complex add-in by following along with the PowerPoint add-in tutorial.
