For more detailed instructions on how to use this script, sign up with your email here:
http://adamloving.com/internet-programming/how-toexport-facebook-page-fans

DISCLOSURE: This javascript runs in your browser pretending to be you 
looking through your page fans. Facebook should have no problem with this, 
but who knows if they will think it is strange to see you looking through 
all your fans so quickly (the script waits 3s before requesting each page). 
I've had no problem running this so far for 1000s of page fans, but I 
cannot be held liable if your Facebook account gets banned or your page 
gets disabled for any reason for using this script.

INSTRUCTIONS:

1. Download Google Chrome Web browser (or Apple Safari)

2. Enable the developer tools

3. Open the javascript console and cut and paste the attached script into the console.

The script will fetch users 100 at a time and output the results into the console which you can then cut and paste into a CSV file.
