Filter Inactive records location in SharePoint

Hi,

I have a requirement of finding SharePoint document locations if there are any related to inactive accounts in CRM. Whenever I go to an inactive account record and open Document location it will create one, if that is not existing.

One way I found is to export all the document locations from SharePoint and inactive accounts from CRM into excel and matching them.

Is there a better way to achieve this?

Thanks in advance for your suggestions.

Cheers.
