My Old post to sort the Address Book on MAC for Duplicates and Corrupt Data was with AppleScript which was not quite efficient and fast, hence rewrote the whole script.
The Script does not delete nor modify any data, hence its safe to use, however i suggest that you should backup the database. the "SortAddressBook Advance 2.0.1RC" does the following
1. Make the following Groups based on Names
"USER Duplicate Names" --> all Contact are sorted on the full Name ie First Name + Last Name
"USER Duplicate First Name" --> all Contact are sorted on the first Name
"USER No Last Name" --> all Contacts with No Last Name are sorted
"USER No Names" --> All Contact with No First and Last Name
