I have a list of many Facebook users with URLs like:
facebook.com/firstname.surname
facebook.com/pseudo
facebook.com/profile.php?id=12345678910xxx1112
How can I create a Custom Audience with these people in http://www.facebook.com/ads/manager/audiences?
Here I don't see "User URL" field (I tried to upload a CSV with the user URL and it doesn't work):

If it's definitely not possible, how to get the other fields that are ok from my users URL list, so that I can feed the audience creation tool with these other fields?
facebook.com/orfacebook.com/profile.php?id=portion off and use the remaining id.
