Build an Excel task pane add-in using Angular
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
Use the Yeoman generator to create an Excel add-in project. Run the following command and then answer the prompts as follows:
- Choose a project type:
Office Add-in Task Pane project using Angular framework
- Choose a script type:
- What do you want to name your add-in?
My Office Add-in
- Which Office client application would you like to support?
After you complete the wizard, the generator will create the project and install supporting Node components.
- Choose a project type:
Navigate to the root folder of the project.
cd "My Office Add-in"
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 key 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/app/app.component.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
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 will start.
npm run dev-server
To test your add-in in Excel, 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) and Excel will open with your add-in loaded.
To test your add-in in Excel Online, 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 workbook in Excel Online and then sideload your add-in by following the instructions in Sideload Office Add-ins in Office Online.
In Excel, choose the Home tab, and then choose the Show Taskpane button in the ribbon to open the add-in task pane.
Select any range of cells in the worksheet.
At the bottom of the task pane, choose the Run link to set the color of the selected range to yellow.
