    I understand how to iterate over a hash and extract key value pairs. 

    This was manageable when dealing with simple binary association but it gets weirder when I import a csv file into a hash with headers.

    The end result is a hash table containing a hash for each line of the imported csv.

    Can someone please give an example of how to iterate over the sub hashes?

    Any help you can provide would be greatly appreciated.

    Thanks,

    Andy
