This project parses Google Calendar data exported as an iCalendar (ICS) file and produces data in a format that is useful for pasting into an invoice template.

The best approach is to:

1. Create a conda environment using the included environment.yml file
2. After activating your new conda environment, run python generate_invoices.py start_date end_date

Specifically, using the Google API, this project will pull data from my personal calendar Cameron Station Commuters and generate a pandas Dataframe that then is parsed for unique passenger names. It then outputs an Excel file with a sheet for each passenger, named using that passenger's name, as well as a summary tab reflecting how frequently each passenger rode with a given driver. These data can then be pasted into the invoice template of your choosing.
