Comprehensive Guide to Microsoft Office Add-ins

Add-ins (or add-ons) are programs that add extra features to Microsoft Office applications, enhancing their functionality and customizing your workflow.

This guide will walk you through the different types of add-ins, how to add them, load them, and remove them from your Microsoft Office applications on both PC and Mac.

Types of Add-ins

There are three main types of add-ins for Microsoft Office applications:

VBA Add-ins

VBA Add-ins are the traditional type of add-ins that enhance the functionality of Office applications. They are relatively easy to build for anyone with a basic understanding of Visual Basic for Applications (VBA). These add-ins are best suited for local operations and operate without requiring an internet connection.

COM Add-ins

COM (Component Object Model) add-ins provide a wide range of customization options and better scalability. They can be distributed through executable files and are typically more powerful than VBA add-ins. However, they require more advanced programming skills to develop.

Web Add-ins

Web Add-ins are the newest solution offered by Microsoft 365. They are designed to run code that interacts with web services, making them ideal for exchanging information with a server. Keep in mind that Web Add-ins require an active internet connection to function, which can sometimes affect their performance.

Adding Add-ins on PC

1. Download the COM add-in installer from a trusted source.
2. Run the installer and follow the installation wizard.
3. The add-in should automatically install and integrate with your Microsoft Office application.

Adding a Web Add-in

To install a Web add-in, do the following:

1. Open your Microsoft 365 application (PowerPoint, Excel, Word, Outlook, OneNote).
2. Go to the “Insert” tab.
3. Click on “Get add-ins” to access the list of available web add-ins.
4. Browse or search for the desired add-in and follow the prompts to install it.

Loading and Unloading Add-ins

If an add-in is installed but not loaded, you can manage it by following these steps:

1. Click on “File” or the Office button at the top left of your application.
2. Select “Options” and then “Add-ins” from the left menu.

Managing Add-ins on Mac

The process for Mac users is slightly different:
