I need a flexible software tool/application that will help me compare the members of 2, or perhaps more, lists and let me identify/extract non-common members.
One practical value of this list processing action is that it will help me invite people already connected in one platform to another one, avoiding invitations to existing connections in the second platform.
Could you please suggest me a suitable software tool (either free or commercial but not web-based)?
I need separate columns for Business Name, Address, Phone, Email, Website, etc.
Please answer if you know of free software to do this, or can explain how to do this with Excel, or with maybe a script or MS Access…
