# csb43
[](https://csb43.readthedocs.io/projects/latest/?badge=latest)
Tools for converting from the Spanish banks' format **CSB norm 43** (*CSB43*).
## csb2format
Convert a **CSB/AEB norm 43** file to other file formats.
Supported formats:
- OFX v1.0.3 (SGML) & v2.1.2 (XML)
- [HomeBank CSV](http://homebank.free.fr/help/06csvformat.html)
- *JSON*
- *YAML*
Additional formats are optionally provided by `tablib`:
- *HTML*
- *ODS*: OpenDocument spreadsheet
- *CSV*, *TSV*: comma- or tab- separated values
- *XLS*: Microsoft Excel spreadsheet
- *XLSX*: OOXML spreadsheet
For an exhaustive list, see package `tablib`.
### Options:
usage: csb2format [-h] [-v] [-s] [--no-sepa] [-df] [-d DECIMAL] [-e ENCODING] [--use-float] [-V]
[-f {csv,dbf,homebank,html,jira,json,latex,ods,ofx,ofx1,rst,tsv,xls,xlsx,yaml}] [-E OUTPUT_ENCODING]
csb_file converted_file
Convert a CSB43 file to another format
options:
-h, --help show this help message and exit
-v, --version show program's version number and exit
csb43 arguments:
csb_file a csb43 file ('-' for stdin)
-s, --strict strict mode (default: False)
--no-sepa do not convert items to SEPA transfers or direct debits (default: True)
-df, --dayfirst use DDMMYY as date format while parsing the csb43 file instead of YYMMDD (default: True)
-d DECIMAL, --decimal DECIMAL
set the number of decimal places for the money amount type (default: 2)
-e ENCODING, --encoding ENCODING
set the input encoding ('cp850' for standard AEB file) (default: latin1)
--use-float export monetary amounts using binary floating point numbers as a fallback (default: str)
-V, --verbose show csb43 warnings (default: True)
output arguments:
converted_file destination file ('-' for stdout)
-f {csv,dbf,homebank,html,jira,json,latex,ods,ofx,ofx1,rst,tsv,xls,xlsx,yaml}, --format {csv,dbf,homebank,html,jira,json,latex,ods,ofx,ofx1,rst,tsv,xls,xlsx,yaml}
format of the output file (default: ofx)
-E OUTPUT_ENCODING, --output-encoding OUTPUT_ENCODING
set the output encoding (default: utf-8)
### Examples
- Converting to OFX format:
$ csb2format transactions.csb transactions.ofx
$ csb2format --format ofx transactions.csb transactions.ofx
or
$ csb2format transactions.csb - > transactions.ofx
From another app to file
$ get_my_CSB_transactions | csb2format - transactions.ofx
- Converting to XLSX spreadsheet format:
$ csb2format --format xlsx transactions.csb transactions.xlsx
- Using cp850 as the input encoding:
$ csb2format --encoding cp850 --format xlsx transactions.csb transactions.xlsx
### Spreadsheets
*ODS*, *XLS* and *XLSX* files are generated as books, with the first sheet
containing the accounts information, and the subsequent sheets
containing the transactions of each one of the accounts.
### Using Python
Parse a *CSB43* file and print the equivalent *OFX* file
```python
# OFX
from csb43.ofx import converter as ofx_converter
from csb43.aeb43 import read_batch
with open("movimientos.csb", "rb") as fd:
batch = read_batch(fd)
# print to stdout
print(ofx_converter.convert_from_aeb43(batch))
```
Parse a *CSB43* file and print the equivalent in a tabular or
dictionary-like file format
```python
from csb43 import read_batch, formats
with open("movimientos.csb", "rb") as fd:
batch = read_batch(fd)
# print 'yaml' format to stdout
o = formats.convert_from_aeb43(batch, 'yaml')
print(o.yaml)
# write 'xlsx' format to file
o = formats.convert_from_aeb43(batch, 'xlsx')
with open("movimientos.xlsx", "wb") as f:
f.write(o.xlsx)
```
Build an AEB43 with a custom context:
```python
import dataclasses
from csb43 import read_batch, get_current_context
# custom context
ctx = dataclasses.replace(get_current_context(), strict=True)
with open("movimientos.csb", "rb") as fd:
batch = read_batch(fd, context=context)
# scoped context
with get_current_context().scoped(strict=True):
with open("movimientos.csb", "rb") as fd:
batch = read_batch(fd)
```
