ledger2beancount

A script to automatically convert Ledger-based textual ledgers to Beancount ones.

Conversion is based on (concrete) syntax, so that information that are not meaningful for accounting reasons but still valuable (e.g., comments, formatting, etc.) can be preserved.

Please read the manual on how to install, configure and use ledger2beancount. The supported features are documented in the manual, too.

Usage

ledger2beancount accepts input from stdin or from a file and will write the converted data to stdout. You can run ledger2beancount like this:

ledger2beancount test.ledger > test.beancount

Installation

Please see the manual for dependencies and installation instructions.
