-# Convert an Office Add-in project in Visual Studio to TypeScript
+# Convert an Office Add-in from JavaScript to TypeScript in Visual Studio
 
-You can use the Office Add-in template in Visual Studio to create an add-in that uses JavaScript, and then convert that add-in project to TypeScript. This article describes this conversion process for an Excel add-in. You can use the same process to convert other types of Office Add-in projects from JavaScript to TypeScript in Visual Studio.
+If your Office Add-in project in Visual Studio starts in JavaScript, you can migrate it to TypeScript without rebuilding the project. This article shows the process for an Excel add-in. You can use the same steps for other Office Add-in project types in Visual Studio.
+
+## What you'll do
+
+- Add the `Microsoft.TypeScript.MSBuild` package so TypeScript files transpile during build.
+- Add `tsconfig.json` and `package.json` settings for TypeScript and type definitions.
+- Rename JavaScript files from `.js` to `.ts` and update code that needs TypeScript changes.
+- Run the converted add-in in Excel.
 
 ## Prerequisites
 
-- [Visual Studio 2022 or later](https://www.visualstudio.com/vs/) with the **Office/SharePoint development** workload installed
+- [Visual Studio 2022 or later](https://visualstudio.microsoft.com/downloads/) with the **Office/SharePoint development** workload installed
 
     > [!TIP]
     > If you've previously installed Visual Studio, [use the Visual Studio Installer](/visualstudio/install/modify-visual-studio) to ensure that the **Office/SharePoint development** workload is installed. If this workload is not yet installed, use the Visual Studio Installer to [install it](/visualstudio/install/modify-visual-studio#modify-workloads).
