Is it possible to export the fans list?
If so, how?

The short answer is Facebook fans cannot be exported.
However, it would be better if you could explain what you mean by exporting. Are you looking for a sort of contact list out the page fans?
You can also check this URL: http://www.fbpagemembers.com. It's a free desktop app for exporting Facebook page fans.
