I've got an early version of a Ruby script I did to parse through the CSV files and print them out in a more concise view. I found that taking my wishlist printout to conventions and stores was kind of burdensome, so I wrote this to parse, reformat and printout out the lists.
It works with both collections and wishlists and can handle it despite which columns you export. I use the headers to figure out which column index is which. It takes the CSV file as an argument and an optional -c flag which will collapse consecutive runs. I find I want to have wishlists printed with each individual number for ease of crossing them off, but I want my collection printed in collapsed view for readability. Your mileage may vary.
It's up on my website at :

Let me know what you think. This might just remain as a one off or if people see value in writing arbitrary tools to work with CBDB data sets, I might try to abstract this into a library.
