Unable to Deploy 3rd Party Excel Web Add-in using available methods

Bob Duffett 1 Reputation point

We created an Excel Web Add-in to replace an XLSM that we’ve been distributing for nearly 20 years.

How can we deploy an Excel Web Add-in to 100’s of existing single tenant web sites that are either on-premise or cloud hosted?

None of these standard Manifest Deployment Options seem to work for us:

• Network Share – non-production and no mac support / version checking.
• AppSource – since the web add-in needs to talk to the user’s app server, the add-in has to be installed on each user’s application server. Is this 100+ apps?
• Microsoft 365 Admin Center – still AppSource. Right?
• SharePoint Catalog – no support for Mac and requires centralized SharePoint use.

Am I missing something?


Why not a capability like WEB DEPLOY (with version checking)?

    If you would like to deploy an add-in to a tenant, the Best solution is through Centralized Deployment manage-deployment-of-add-ins

    The tenant admin could deploy the add-in, it doesn't need installation by single users.
