Build your first PowerPoint add-in

In this article, you'll walk through the process of building a PowerPoint add-in by using jQuery and the Office JavaScript API.

Create the add-in

You can create an Office Add-in by using Visual Studio or any other editor. Tell us what editor you'd like to use by choosing one of the following tabs:

Prerequisites

Create the add-in project

  1. On the Visual Studio menu bar, choose File > New > Project.

  2. In the list of project types under Visual C# or Visual Basic, expand Office/SharePoint, choose Add-ins, and then choose PowerPoint Web Add-in as the project type.

  3. Name the project, and then choose OK.

  4. In the Create Office Add-in dialog window, choose Add new functionalities to PowerPoint, and then choose Finish to create the project.

  5. Visual Studio creates a solution and its two projects appear in Solution Explorer. The Home.html file opens in Visual Studio.

Explore the Visual Studio solution

When you've completed the wizard, Visual Studio creates a solution that contains two projects.

Project Description
Add-in project Contains only an XML manifest file, which contains all the settings that describe your add-in. These settings help the Office host determine when your add-in should be activated and where the add-in should appear. Visual Studio generates the contents of this file for you so that you can run the project and use your add-in immediately. You change these settings any time by modifying the XML file.
Web application project Contains the content pages of your add-in, including all the files and file references that you need to develop Office-aware HTML and JavaScript pages. While you develop your add-in, Visual Studio hosts the web application on your local IIS server. When you're ready to publish the add-in, you'll need to deploy this web application project to a web server.

Update the code

  1. Home.html specifies the HTML that will be rendered in the add-in's task pane. In Home.html, replace the <body> element with the following markup and save the file.

    <body class="ms-font-m ms-welcome">
        <div id="content-header">
            <div class="padding">
                <h1>Welcome</h1>
            </div>
        </div>
        <div id="content-main">
            <div class="padding">
                <p>Select a slide and then choose the buttons to below to add content to it.</p>
                <br />
                <h3>Try it out</h3>
                <button class="ms-Button" id="insert-image">Insert Image</button>
                <br/><br/>
                <button class="ms-Button" id="insert-text">Insert Text</button>
            </div>
        </div>
    </body>
    
  2. Open the file Home.js in the root of the web application project. This file specifies the script for the add-in. Replace the entire contents with the following code and save the file.

    'use strict';
    
    (function () {
    
        // The initialize function must be run each time a new page is loaded
        Office.initialize = function (reason) {
            $(document).ready(function () {
                $('#insert-image').click(insertImage);
                $('#insert-text').click(insertText);
            });
        };
    
        function insertImage() {
            Office.context.document.setSelectedDataAsync(getImageAsBase64String(), {
                coercionType: Office.CoercionType.Image,
                imageLeft: 50,
                imageTop: 50,
                imageWidth: 400
            },
                function (asyncResult) {
                    if (asyncResult.status === Office.AsyncResultStatus.Failed) {
                        console.log(asyncResult.error.message);
                    }
                });
        }  
    
        function insertText() {
            Office.context.document.setSelectedDataAsync("Hello World!",
                function (asyncResult) {
                    if (asyncResult.status === Office.AsyncResultStatus.Failed) {
                        console.log(asyncResult.error.message);
                    }
                });
        }
