Weird, I've decided to leave FB and was working on doing this an hour ago. I ended up using: https://chrome.google.com/webstore/detail/ficlccidpkaiepnnbo...

You can also use this method: http://techcrunch.com/2010/11/12/how-to-mass-export-all-of-y...

but for me it only exported contacts that had their email address visible. "Facebook Friend Exporter" worked better.

wtf.. Why screen scrape Facebook from a bookmarklet, when the Graph API gives you all this and more in JSON.

I just had to do the very same thing, except instead of Facebook, it was a contact list in a proprietary medical office database. Since my programming skills are limited to Basic and Pascal, I just used AutoHotKey and the AutoHotKey Recorder. After a little editing, i.e. adding a test for empty boxes and putting the whole script in a loop, it was working fine. I considered teaching myself Ruby, but I knew it would be much faster to use AutoHotKey. But it's really interesting to see the same process in a proper computer language

Just be careful, Facebook monitors for scraping activity and has deleted accounts over this in the past.

Would be great if it offered a variable sleep option, to make it a bit less of a dead giveaway.

Everyone quick! Get it, before the cease and desist letter comes. ( backup: http://piratepad.net/VKHtw0Txli )

After browsing the source I thought there has to be a better way

Cool stuff. Got a lot of insight from the code.
