Deploy to Users Using Centralized Deployment
Office 365 Administrators can easily deploy the add-in to everyone or specific users using O365 Centralized Deployment.
See details here: https://docs.microsoft.com/en-us/office365/admin/manage/manage-deployment-of-add-ins
The quickest method is to go to the add-in page on the Office App Store, then click "GET IT NOW". You must be signed in as an Office 365 administrator.
Alternatively, from the Microsoft 365 Admin Center:
In the admin center, go to the Settings > Services & add-ins page.
Select Deploy Add-in at the top of the page. On the overview page, select Next.
Select Choose from the Store.
Search for AnalysisPlace, choose Excel-to-Word Document Automation, then select GET IT NOW. Once you've selected your add-in, you will need to agree to some additional terms and conditions in order to proceed.
NOTE: With the Office Store option, updates and enhancements to the add-in will automatically be made available to users without your intervention.
On the next page, select Everyone, Specific users/groups or Just me to specify who the add-in is deployed to. Use the Search box to find the users or groups who you want to deploy the add-in to.
NOTE: Learn about the other states that apply to an add-in. See Add-in states later in this topic.
A green tick will appear when the add-in has been deployed. You can follow the on-page instructions to test that the add-in has deployed successfully.
