A collection of code samples for building Microsoft Office Add-ins on the Microsoft 365 platform, covering Excel, Outlook, Word, and PowerPoint. It includes hello-world examples, completed tutorials, and scenario-based samples to help developers learn and build Office Add-ins.

Use cases

• learn how to build an Office Add-in
• find sample code for Excel task pane add-ins
• build an Outlook add-in that inserts content into messages
• understand the fundamental parts of an Office Add-in manifest
• get started with Microsoft 365 add-in development
• see completed versions of Office Add-in tutorials

When to choose

• you are developing Office Add-ins for Microsoft 365 apps like Excel, Word, Outlook, or PowerPoint
• you want working reference code for task pane or content add-ins
• you are following Microsoft's Office Add-in tutorials and want the completed versions

When to avoid

• you need a production-ready add-in framework rather than sample code
• you are building VSTO or COM add-ins instead of web-based Office Add-ins
• you need samples for non-Microsoft office suites
