pyTunesConnect is an open source python script I created that will automatically download your sales reports from iTunes Connect, store the data in a MySQL database. The data is then rendered in a web page with interactive java charts showing you the breakdown of new downloads and re-downloads along with regional data.
The script can be found on the project’s Google Code page: http://code.google.com/p/pytunesconnect/
I have hosted a copy of the documentation here: http://www.jonathancarroll.net/pytunesconnect/docs/index.html
If you have questions about installing or are having trouble feel free to leave a comment on this page and I will reply. If you are interested in contributing to the project let me know and I will set you up on the project in Google Code.
