@georgiana-b Np, good. Concerning the other discrepancy (~500k vs. ~175k), this is just (the extremely confusing) terminology. Each "contract award notice" has multiple "contract awards", so when the CAN file has 500k rows, these are actually 500k "contract awards", not "contract award notices". I think this point is not important for your network visualisation, because you work only with "contract awards", but if you're interested, it's explained in some detail in the open data documentation.
@victor Yes, I will definitely add the row number / MB size, hopefully next week with a new re-upload. (There is actually also a bunch of smaller mistakes that I need to correct as well, sorry for that. Nothing that should mess up your work though.) Concerning the checksum - what exactly does that mean for a .csv? I assume you don't mean that I should simply add a line into the csv counting the number of other lines, right? (Sorry if it's a very naive question :). )
Thanks for the offer, always appreciated! I'll think about it and come back to you :).
