I've written a utility to parse Apple's sales reports (S_D* S_W*) and compute totals per currency.

It can parse a single file or multiple files.

The output looks like this:
Code:
Apps count: 2

AppName       Records   Sales Updates
-------------------------------------
Myapp0             16      44       0
Myapp Pro          11      33       0

AppName     U   AUD U  CAD  U   EUR U  GBP U     JPY  U   USD
-------------------------------------------------------------
Myapp0      1  1.58 3 4.20 19 18.43 2 1.44 3  483.00 16 22.40
Myapp Pro   2 16.54 0 0.00 13 63.18 1 3.65 4 3360.00 13 91.00
