This is a set of scripts I use to do personal accounting.

I don't like to account by hand, do most of my purchasing with a card and wanted a (semi) automated way to sort through the CSVs one can download from most banks.

If you bank with a credit union which uses cue-branch.com, you're in luck, because I do as well. A converter is also provided for Shift Payments, which will track both your USD price and the crypto you sold for it.

The resulting ledger is in the order of the rows of the CSV, unless it's reverse. To sort them use the creatively-named date_sort.py. Note that it reads a limited subset of the ledger-cli language and tries to do the right thing with lines it doesn't recognize; if you have a use that breaks it, I'm interested, please file an issue.

The 'driver' is accounts_map.json This is a big Object, the keys of which are accounts, and the values are either an Array or an Array of Arrays, with two entries: the first is a regular expression to search in the merchant description, the second (optional) is something to call it.

Any merchant description which isn't recognized is bucketed into "Expenses:Miscellaneous:Other", and the decription printed along with the date and value. It's about as easy to change the ledger entry as to add to the JSON map so I tend to do the latter, making accounting easier over time (with considerable spikes when I travel).

Sample CSVs are included for both formats. Pull requests with (anonymized) samples of other formats are welcomed.

To extend, add a way to recognize the CSV by header(s) to detect_csv_type then implement a function in the extract(row) family which returns a log.

uses arrow and titlecase, should work with Python 3 but I wouldn't know, because no one pays me to maintain more than one python environment on my laptop and life is too short.
