Cisdem ContactsMate (formally known as ContactManager) is a great Mac contacts manage application. Beside to backup all of the Contacts, edit the Contacts fields, find, analyze, report, and fix dozens of problems with OS X Contacts and export Mac Address Book to CSV, vCard, TXT, Docx, HTML, Excel, Numbers, and Pages format for easy Contacts backup or sync. The application adds new function: make group for contacts, batch fix similar problematic contacts, manually set suffix or prefix. You can make groups respectively for your family, friends, colleagues, clients or work contacts.
The options are endless, making it much more efficient and easier to find the targeted one(s). After the problematic contacts are found out and sorted, you can perform bulk modifications on the similar questionable Contacts or neglect these problems as you will. You can add or delete available suffixes and prefixes themselves to improve the accuracy of problems scanning. Besides this, suffixes and prefixes can be added in their own languages, which is very handy for users from non-English speaking countries.
