This tool reads MBOX files from Google Takout, parses Curve (<- contains referral code) transaction emails and outputs CSV files which then can be imported to budget tracking apps, like Lunch Money.
The app takes a single parameter which is a path to an MBOX file containing all the emails.
python convert.py --input receipts.mbox
Parsed transactions will be grouped by month and placed to the target/ directory.
Any unparsed emails will be saved under the target/ directory with a unparsed- prefix.
