Description:

beancountdkb 1.0.0

Beancount DKB Importer




beancount-dkb provides importers 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 main is the
development branch so stable is what you should be installing from.
Note that v1.x will only work with Beancount 3.x, while v0.x will only work with
Beancount 2.x, due to incompatibilities between Beancount 3.x and 2.x.
Usage
If you're not familiar with how to import external data into Beancount, please read
this guide first.
Beancount 3.x
Beancount 3.x has replaced the config.py file based workflow in favor of having a
script based workflow, as per the changes documented here. As a result, the importer's
initialization parameters have been shifted to pyproject.toml.
Add the following to your pyproject.toml in your project root.
[tool.beancount-dkb.ec]
iban = "DE99 9999 9999 9999 9999 99"
account_name = "Assets:DKB:EC"
currency = "EUR"

[tool.beancount-dkb.credit]
card_number = "9999 9999 9999 9999"
account_name = "Assets:DKB:Credit"
currency = "EUR"

Run beancount-dkb-ec or beancount-dkb-credit to call the importer. The identify
and extract subcommands would identify the file and extract transactions for you.
$ beancount-dkb-ec extract transaction.csv >> you.beancount
$ beancount-dkb-credit extract transaction.csv >> you.beancount

Beancount 2.x
Adjust your config file to include ECImporter and CreditImporter
(depending on what account you're trying to import).
Add the following to your config.py.
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',
),

CreditImporter(
CARD_NUMBER,
'Assets:DKB:Credit',
currency='EUR',
)
]

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.
Add the meta_code parameter to the ECImporter initializer.
Beancount 3.x
[tool.beancount-dkb.ec]
iban = "DE99 9999 9999 9999 9999 99"
account_name = "Assets:DKB:EC"
meta_code = "code"

Beancount 2.x
...
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

Pattern-matching Transactions
It's possible to give the importer classes hints if you'd like them to include a
second posting based on specific characteristics of the original transaction.
For instance, if the payee or the description in a transaction always matches a
certain value, it's possible to tell the ECImporter or CreditImporter to
automatically place a second posting in the returned lits of transactions.
ECImporter
ECImporter accepts payee_patterns and description_patterns arguments, which should
be a list of (pattern, account) tuples.
Beancount 3.x
[tool.beancount-dkb.ec]
iban = "DE99 9999 9999 9999 9999 99"
account_name = "Assets:DKB:EC"
payee_patterns = [
["REWE", "Expenses:Supermarket:REWE"],
["NETFLIX", "Expenses:Online:Netflix"],
]

Beancount 2.x
CONFIG = [
ECImporter(
IBAN_NUMBER,
'Assets:DKB:EC',
currency='EUR',
payee_patterns=[
('REWE', 'Expenses:Supermarket:REWE'),
('NETFLIX', 'Expenses:Online:Netflix'),
],
),

CreditImporter
CreditImporter accepts a description_patterns argument, which should be a list of
(pattern, account) tuples.
Beancount 3.x
[tool.beancount-dkb.credit]
card_number = "9999 9999 9999 9999"
account_name = "Assets:DKB:Credit"
currency = "EUR"
description_patterns=[
['REWE', 'Expenses:Supermarket:REWE'],
['NETFLIX', 'Expenses:Online:Netflix'],
]

Beancount 2.x
CONFIG = [
CreditImporter(
CARD_NUMBER,
'Assets:DKB:Credit',
currency='EUR',
description_patterns=[
('REWE', 'Expenses:Supermarket:REWE'),
('NETFLIX', 'Expenses:Online:Netflix'),
],
)
