Hi stormid,
I came across your thread while searching for the same solution. Currently I use Acymailing component that can export users lists. You can select AcyMailing fields to export. You can create users list in AcyMailing that updates based on criteria and link it to CB Users. I used it to export a CSV file and then manuplulated the file in excel. Hope this helps. I am still looking for a solution to have this feature in CB and easy to implement. Once I had this component but now it does not support Joomla 2.5.
Good luck
