There’s an app called “Export Friends” that will save you friends names, city, birthday and their current location in a CSV (text) file that you then import into Excel, Gmail or any other web email program.
Then there are social plug-ins that can sync photos and status updates of your Facebook friends with matching contacts in Outlook.
The problem is that none of these apps can download what you are looking – the phone numbers and email addresses of your Facebook friends. There are Greasemonkey scripts and other hacks that can pull this information from Facebook through “web scraping” but don’t ever take that route as Zuckerberg’s army might ban your account forever.
Export Email Addresses of your Facebook Contacts
Facebook APIs don’t expose email addresses of users and hence none of the Facebook apps can provide you with the actual contact data of your friends. There’s however a simple (and perfectly legal) workaround that can help you easily download all your friends email addresses from Facebook’s walled garden.
Go to address.yahoo.com and click the Facebook icon. A login dialog should pop-up, just sign-in with your Facebook credentials and within seconds, you entire Facebook address book will be available inside your Yahoo Mail Account. Once the import is done, click this link to download a CSV file with the email addresses of all your Facebook contacts to your desktop.
You can then import the CSV file into Gmail Contacts, LinkedIn, your phone address book or any of the social sites where you want to connect with your existing Facebook circle.
Update: If Yahoo! is unable to import your Facebook Address book, open your Facebook page and choose “Application Settings” under Account. Next remove the “Yahoo! Contact Importer” application from your Facebook profile and try the steps mentioned in the video again.
