csv2ofx

INTRODUCTION

csv2ofx is a Python library and command line interface program that converts CSV files to OFX and QIF files for importing into GnuCash or similar financial accounting programs. csv2ofx has built in support for importing csv files from mint, yoodlee, and xero.

Requirements

csv2ofx has been tested and is known to work on Python 3.7, 3.8, and 3.9; and PyPy3.7.

INSTALLATION

(You are using a virtualenv, right?)

sudo pip install csv2ofx

Usage

csv2ofx is intended to be used either directly from Python or from the command line.

Library Examples

normal OFX usage

import itertools as it

from meza.io import read_csv, IterStringIO
from csv2ofx import utils
from csv2ofx.ofx import OFX
from csv2ofx.mappings.default import mapping

ofx = OFX(mapping)
records = read_csv('path/to/file.csv', has_header=True)
groups = ofx.gen_groups(records)
trxns = ofx.gen_trxns(groups)
cleaned_trxns = ofx.clean_trxns(trxns)
data = utils.gen_data(cleaned_trxns)
content = it.chain([ofx.header(), ofx.gen_body(data), ofx.footer()])

for line in IterStringIO(content):
    print(line)

normal QIF usage

import itertools as it

from tabutils.io import read_csv, IterStringIO
from csv2ofx import utils
from csv2ofx.qif import QIF
from csv2ofx.mappings.default import mapping

qif = QIF(mapping)
records = read_csv('path/to/file.csv', has_header=True)
groups = qif.gen_groups(records)
trxns = qif.gen_trxns(groups)
cleaned_trxns = qif.clean_trxns(trxns)
data = utils.gen_data(cleaned_trxns)
content = it.chain([qif.gen_body(data), qif.footer()])

for line in IterStringIO(content):
    print(line)

normal usage

csv2ofx file.csv file.ofx

print output to stdout

csv2ofx ~/Downloads/transactions.csv

read input from stdin

cat file.csv | csv2ofx

qif output

csv2ofx -q file.csv

specify date range from one year ago to yesterday with qif output

csv2ofx -s '-1 year' -e yesterday -q file.csv

use yoodlee settings

csv2ofx -m yoodlee file.csv

Special cases

Some banks, like UBS Switzerland, may provide CSV exports that are not readily tractable by csv2ofx because of extra header or trailing lines, redundant or unwanted columns. These input files can be preprocessed with the shipped utilz/csvtrim shell script. F.i., with mapping ubs-ch-fr:

csvtrim untrimmed.csv | csv2ofx -m ubs-ch-fr

CUSTOMIZATION

Code modification

If you would like to import csv files with field names different from the default, you can modify the mapping file or create your own. New mappings must be placed in the csv2ofx/mappings folder (otherwise you must use the ). The mapping object consists of a dictionary whose keys are OFX/QIF attributes and whose values are functions which should return the corresponding value from a record (csv row). The mapping function will take in a record, e.g.,

{'Account': 'savings 2', 'Date': '1/3/15', 'Amount': 5000}

The most basic mapping function just returns a specific field or value, e.g.,

from operator import itemgetter

mapping = {
    'bank': 'BetterBank',
    'account': itemgetter('Account'),
    'date': itemgetter('Date'),
    'amount': itemgetter('Amount')}

But more complex parsing is also possible, e.g.,

mapping = {
    'account': lambda r: r['Details'].split(':')[0],
    'date': lambda r: '%s/%s/%s' % (r['Month'], r['Day'], r['Year']),
    'amount': lambda r: r['Amount'] * 2,
    'first_row': 1,
    'last_row': 10,
    'filter': lambda r: r['Amount'] > 10,
}

Required field attributes

attribute	description	default field	example
account	transaction account	Account	BetterBank Checking
date	transaction date	Date	itemgetter('Transaction Date')
amount	transaction amount	Amount	itemgetter('Transaction Amount')

Optional field attributes

attribute	description	default field	default value	example
desc	transaction description	Reference	n/a	shell station
payee	transaction payee	Description	n/a	Shell
notes	transaction notes	Notes	n/a	for gas
check_num	the check or transaction number	Row	n/a	2
id	transaction id	check_num	Num	n/a
bank	the bank name	n/a	account	Bank
account	transaction account type	n/a	checking	savings
account_id	transaction account id	n/a	hash of account	bb_checking
type	transaction type (either debit or credit)	n/a	CREDIT if amount > 0 else DEBIT	debit
balance	account balance	n/a	n/a	$23.00
class	transaction class	n/a	n/a	travel

Optional value attributes

date_fmt	custom QIF date output format	%m/%d/%y	%m/%d/%Y
dayfirst	interpret the first value in ambiguous dates (e.g. 01/05/09) as the day (ignored if parse_fmt is present)	False	True
parse_fmt	transaction date parsing format		%m/%d/%Y
first_row	the first row to process (zero based)	0	2
last_row	the last row to process (zero based, negative values count from the end)	inf	-2

Contributing

Please mimic the coding style/conventions used in this repo. If you add new classes or functions, please add the appropriate doc blocks with examples. Also, make sure the python linter and nose tests pass.

Ready to contribute? Here's how:

1. Fork and clone.

git clone [email protected]:<your_username>/csv2ofx.git
cd csv2ofx

2. Setup a new virtualenv

mkvirtualenv -i pkutils csv2ofx
activate csv2ofx
python setup.py develop
pip install -r dev-requirements.txt

3. Create a branch for local development

git checkout -b name-of-your-bugfix-or-feature

4. Make your changes, run linter and tests (see above), and submit a pull request through the GitHub website.

Adding Mappings

How to contribute a mapping:

1. Add the mapping in csv2ofx/mappings/
2. Add a simple example CSV file in data/test/.
3. Add the OFX or QIF file that results from the mapping and example CSV file in data/converted/.
4. Add a csv2ofx call for your mapping to the tests in tests/test.py, in PRE_TESTS. If you added an OFX (not QIF) converted file, pay attention to the -e (end date) and -D (server date) arguments in the test- otherwise tests may pass on your workstation and fail on the build server.
5. Ensure your test succeeds (see above).
