ToLedger originated as a personal project to convert my bank statements to the open source ledger format. I have made some changes to make it more generally applicable, allowing for other banks to be added.

Currently this library is only known to work with the export files of ING Bank (NL) and Bitstamp, but extending it for similar CSV exports should be trivial.

Usage: 
  toledger.py <format> [options] 
  toledger.py <format> [options] <input>
  toledger.py <format> [options] <input> <output>
  toledger.py (-h | --help)

Options:
  -a --append    Append to the output file if it exists.
  -b --balance   Get the initial balance (if possible)
  --from=<from>  Account to get balances from. 
  --to=<to>      Account to send transactions to. 
  --name=<name>  Account name.
  --hash         Save a hash of the transaction for duplicate removal
  -c --code      Use the currency code, e.g. EUR
  -s --symbol    Use the currency symbol, e.g. €  
  -h --help      Show the usage guidelines.

Apart from downloading this repository, you can install the latest release with pip install toledger

If you wish to contribute to this project, here's a feature wishlist:

• Add different formats for different banks (see toledger/bankstatements.py)
• Interactive mode, manually adding and changing transaction details
• Smart transaction labeling, based on specification files or existing Ledger files
• Checking the output file for duplicates
• Convert to using a Ledger library for Python, instead of writing directly to files (better and more output formatting options)
• Save the meta information in the output file
• Python 2 compatibility
• Unit tests
• Any other suggestions are also welcome, especially if they improve extensibility and compatibility

There are also some design conventions:

• PEP 8 (within reason)
• All options should be reachable from the command line, using docopt
• stdin and stdout compatibility
• Error handling with built-in exceptions (with custom messages)
