elv 1.0.1

Parser and query API for bank CSV account transactions

Elv

Elv is a small utility for parsing exported CSV files from the online Norwegian bank Jæren Sparebank.

I use it for personal purposes, but decided to simply upload the code anyway, in case anyone wants to do the same.

If you want to contribute other formats, please send pull requests on the project’s GitHub page at

Use the “export data” feature in the online bank, and you should be able to parse the file using Elv.

Features

• Parses CSV file from bank containing transactions

• Money is stored in exact decimals (as you should do; never use floats for stuff like this)

• Contains a simple Python query API for sorting through large collections of transactions.

• Can optionally put transactions in an in-memory SQLite3 database for even better queries.

Norwegian short description

Elv er en Python modul for å lese banktransaksjoner eksportert fra banken din som en CSV-fil. Foreløpig er det kun Jæren Sparebank som jeg vet er støttet, men du kan nok ganske enkelt legge til lesere for andre format.

Installation

You can install from setup.py:

$ python setup.py install # you may have to run as sudo

or from PyPI:

$ pip install elv

Example usage

If you have the bank account transactions in a file called data.csv, you can simply do:

$ python
>>> import elv
>>> transactions = elv.parse("data.csv")
>>> transactions
<Transactions:400 items from 2009-01-27 to 2014-09-29>
>>> transactions[0]
<Transaction:2014-09-29 2014-09-29 -2677.00  29519.13 'Vacation'>
>>> transactions[0].xfer
datetime.date(2014, 9, 29)
>>> transactions[0].posted
datetime.date(2014, 9, 29)
>>> transactions[0].amount
Decimal('-2677.00')

You can also get an in-memory SQLite3 database by doing:

>>> db = transactions.to_sqlite3()
>>> db
<sqlite3.Connection object at 0x10f31e200>
>>> db.execute("SELECT * FROM Transactions").next()
(0, datetime.date(2014, 9, 29), datetime.date(2014, 9, 29),
 u'Vacation', Decimal('-2677'), Decimal('29519.13'))

The CSV File Format

The CSV file should be a plain text file with the ISO-8859-1 encoding (aka Latin1). It looks like this:

"31-12-2014";"31-12-2014";"Test 1";"-497,78";"5.520,09"
"30-12-2014";"31-12-2014";"Test 2";"-100,00";"6.017,87"
"30-12-2014";"31-12-2014";"Test 3 --æøåÆØÅ--";"-145,47";"6.117,87"
"30-12-2014";"30-12-2014";"Test 4";"-457,24";"6.263,34"
"29-12-2014";"29-12-2014";"Test 5";"-108,30";"6.720,58"

The fields are as follows:

• Date when the transaction was placed, in format "DD-MM-YYYY".

• Date when the transaction was posted (“bokført”).

• A message associated with the transaction, set by the one making the transaction.

• The amount deposited or deducted from the account in NOK (Norwegian kroner) in format "-123,45", always two decimals and an optional sign.

• The balance of your account after this transaction was completed.

The file itself contains no headers, and can contain many such transactions, one per line.
