# お<ruby>金<rt>かね</rt></ruby> 【okane】

_okane_ is a pure Python parser for bank statements in camt.053 XML format [[1]], in dialect
used by the Czech Banking Association (ČBA) [[2]].

It parses `BkToCstmrStmt` XML element into `okane.BankToCustomerStatement` which is
a Pydantic model. It can also work as a CLI tool, converting camt.053 XML files to JSON or CSV.

## Installation

```shell
pip install okane

# or, if you'd like to use the CSV, XLSX export features and access the data as `pd.DataFrame`
pip install okane[pandas]
```

## Example

### Python API

    >>> import okane
    >>> statement = okane.BankToCustomerStatement.from_file("./tests/data/test2.xml")
    >>> statement.opening_balance
    Balance(amount=Decimal('1000.00'), currency='CZK', date=datetime.date(2023, 3, 1))
    >>> statement.transactions[5].amount
    Decimal('1000.00')
    >>> statement.transactions[5].currency
    'CZK'
    >>> statement.transactions[5].related_account_id
    AccountId(iban='LT6632xxxxxx', id=None)
    >>> statement.transactions[5].related_account_bank_id
    BankId(bic='REVOLT21', id=None)
    >>> statement.transactions[3].ref
    TransactionRef(message_id='XXX', end_to_end_id='XXX', account_servicer_ref=None, payment_invocation_id=None, instruction_id=None, mandate_id=None, cheque_number=None, clearing_system_ref=None)
    >>> df = statement.as_dataframe()

### Command-line interface

```shell
head ./tests/data/test2.xml
```

```xml
