beancount-dkb 0.10.0

Beancount Importer for DKB CSV exports

Beancount DKB Importer

beancount-dkb provides an Importer for converting CSV exports of DKB (Deutsche Kreditbank) account summaries to the Beancount format.

Installation

$ pip install beancount-dkb

In case you prefer installing from the Github repository, please note that master is the development branch so stable is what you should be installing from.

Usage

If you're not familiar with how to import external data into Beancount, please read this guide first.

Adjust your config file to include ECImporter and CreditImporter (depending on what account you're trying to import).

A sample configuration might look like the following:

from beancount_dkb import ECImporter, CreditImporter

IBAN_NUMBER = 'DE99 9999 9999 9999 9999 99' # your real IBAN number

CARD_NUMBER = '9999 9999 9999 9999'         # your real Credit Card number

CONFIG = [
    ECImporter(
        IBAN_NUMBER,
        'Assets:DKB:EC',
        currency='EUR',
        file_encoding='utf-8',
    ),

    CreditImporter(
        CARD_NUMBER,
        'Assets:DKB:Credit',
        currency='EUR',
        file_encoding='utf-8',
    )
]

Once this is in place, you should be able to run bean-extract on the command line to extract the transactions and pipe all of them into your Beancount file.

$ bean-extract /path/to/config.py transaction.csv >> you.beancount

Transaction Codes as Meta Tags

By default, the ECImporter prepends the transaction code ("Buchungstext") to the transaction description. To achieve shorter descriptions and use meta tags to query for certain transaction codes, the importer may be configured to store the transaction code in a user provided meta tag.

The following configuration instructs the importer to use a meta tag code to store transaction codes:

...
CONFIG = [
    ECImporter(
        IBAN_NUMBER,
        'Assets:DKB:EC',
        currency='EUR',
        meta_code='code',
    ),
...

This is how an example transaction looks without the option:

2021-03-01 * "Kartenzahlung" "XY Supermarket"
    Assets:DKB:EC                        -133.72 EUR

And this is the resulting transaction using meta_code='code'

2021-03-01 * "XY Supermarket"
    code: Kartenzahlung
    Assets:DKB:EC                        -133.72 EUR

FAQ

ERROR:root:Importer beancount_dkb.ec.ECImporter.identify() raised an unexpected error: 'utf-8' codec can't decode byte 0xf6 in position 17: invalid start byte

Change the file_encoding parameter. It seems like the CSV exports are ISO-8859-1 encoded, but utf-8 seems like a useful default.
