Use this template to get a version of the Full Characteristics Block writeups you find in the backs of books. This is a fan made version not the official HERO Games export template.
AFAIK there is no standard way of writing out the FCB for 6th edition as each book I looked at was a little different. This is my own personal format that follows the 6e1 book and the Champions Villains books closest.
You'll still have to do a some formatting by hand, in particular the Powers and Complications sections will need to be massaged a bit to get them into the proper format. The export format should get you 90% of the way there though, I hope!
