My inclination would be to print the whole thing out and munge it with a Perl script. Then import it back into Excel for the graphing.
Doing the monthly totals in Perl would be trivial; doing the weeklies might be simpler if you convert the dates into Unix time_t (seconds since 1970-01-01), which Perl cn do pretty easliy.
