I am kind of just brainstorming here. I have a massive list of contacts that I am try to clean to the best of my ability before handling an import. I have Account Numbers in column A and First / Last in B & C, column D are phone numbers & column E are extensions, and finally column F is the email address. Would there be a way to compare Account Numbers and email addresses and when it hits a duplicate of both it moves the value from D, or maybe even D & E, into Column H? I am running into contacts that have multiple phone numbers and I cannot be sure which is accurate and I would like to not have to delete them. I believe I may be able to doctor something up on my own (maybe?) if it was only just one duplicate but there are times where one account number could have two or more duplicate email addresses (due to multiple phone numbers). The columns would be sorted so that the emails are in alphabetical order and then the account numbers would be sorted from smallest to largest so technically all matching email addresses for the specific account number would be together.

Create two additional columns - first one concatenating the Account Number and email address and the second one, a countif, counting how many occurrences of the concatenated Account Number and email address values are in your massive list, then you can filter them, where the contif value is greater than 1 and take whatever your next step is to verify values
