How To:
In the file called ms_test.php, find where it says 
"LOGIN_EMAIL"
and
"PASSWORD"
and change those.
LEAVE THE QUOTES IN PLACE
Save the file.
Upload these two files to your server.
point your web browser to https://where-you-put-the-file-on-your-server/ms_test.php
and what will result is a CSV file of all your MySpace friends and their demographic information.  Also included is the URLs to "send message" etc, and some other useful things.
View the source of the page and copy it into a PlainText text file
Name the text file with the extension .csv 
Now you should be able to work with your myspace friends in Excel 

There is nothing malicious about this simple application.  No viruses, spyware etc.  It only does what it's supposed to do: scrape your friends so you can more easily work with your social network data.

If you are of the camp that feels that people scraping their own myspace contacts is unethical, I suggest that you consider that all the pages are already available and the data they contain is rendered in HTML which can be freely accessed already.  This is just a tool to make it easier to get the useful data separated from the clutter.

Finally, this is possibly against MySpace's Terms Of Service, so use at your own risk.
