Exporter for Contacts (was Export Address Book) is a popular and powerful Mac app to export contact data from Apple’s Contacts into various formats, capable of organizing export setups in customizable templates to make repeated exports a lot easier. The app lets you export selected contacts, groups, and whole address books to a CSV or a native Excel file (great for importing stuff into FileMaker), and many, many other formats, such as tab-delimited text, HTML, XML+XSLT, and customizable vCards. It lets you decide which contact fields will be exported and in what order. The app comes with predefined export templates for common applications such as Outlook for Windows or Gmail.
