Data Plus for Excel is a SaaS application that contains a collection of the most powerful add-ins for working with data in Excel. The first add-in in the collection is Compare and Merge for Excel.

Data Plus for Excel provides subscription plans to the containing add-ins that, once purchased, allow licenses to be assigned to users in Microsoft 365 Admin Center. When a user starts the add-in, the add-in checks for a valid license (including a 30 day trial). With a valid license, the user enters and starts using the add-in.
