To export your address book, go to Address Book at the top of the window. On the left side, click “Export Contacts,” and an excel document will begin downloading. This will contain a list of your contacts and their associated information.
You can also export contacts from a specific contact tag. For example, if you want to download a contact list for only people working for John Doe Entertainment, you can click the tag for that company, and export only those addresses associated with that tag. Just click on the desired tag, and then click “Export Contacts.”
