Convert Billings.app exported slip ".bex" file into Freckle-style CSV

gistfile1.py

import csv
import glob
import plistlib

clientProject = 'My Project'
for filename in glob.glob("*.bex"):
    root = plistlib.readPlist(filename)
    with open(filename+'.csv', 'wb') as out:
        out = csv.writer(out)
        out.writerow(['Date', 'Person', 'Client/Project', 'Minutes', 'Tags', 'Description', 'Billable', 'Invoiced', 'Invoice Reference'])
        for slip in root.objects:
            slip = dict(slip)
            desc = slip.pop('name')
            who = slip.pop('owner.name')
            timeEntries = slip.pop('timeEntries')

            print who, desc
            print slip
            tags = 'from_billings_app'
            for te in timeEntries:
                date = te.startDateTime.date()
                delta = (te.endDateTime - te.startDateTime).total_seconds()
                minutes = int(delta/60)
                if minutes>=1:
                    out.writerow([date, who, clientProject, minutes, tags, desc,'yes','no',None])

It's very rough, but it let me give freckle a real try using my data!

Does this work?
