## Install Office Add-in from Excel

This is the easiest method to install Coherent Assistant if you have Microsoft 365 and is permitted by your organization.

In Excel, from the **Home** ribbon then click **Add-Ins**. Search for Coherent Assistant and install. For more detailed instructions, follow the documentation from Microsoft in [View, manage, and install add-ins for Excel, PowerPoint, and Word](https://support.microsoft.com/en-us/office/view-manage-and-install-add-ins-for-excel-powerpoint-and-word-16278816-1948-4028-91e5-76dca5380f8d).

## Deploy from the Microsoft 365 admin center

This is the recommended method to install Coherent Assistant for organizations that prevent users from installing their own add-ins. This needs to be done by a Microsoft 365 administrator.

Follow the documentation from Microsoft. From the AppSource store, look for Coherent Assistant.
