Online vCard Converter
The lack of a decent export option from the Address Book in the Mac OS is troubling. I’ve tried various free converters in the past, with mixed success. Finally, I’ve found a very easy web page that does the work for you. In Address Book, export all of your contacts as vCards. Then send them through the online converter for the output of your choice. It works beautifully.
This is sweet! Thanks for finding it and posting the link.
