ledger2beancount

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

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

ledger2beancount supports the file formats from:

• ledger
• hledger

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 installation information for dependencies and installation instructions.

Documentation

ledger2beancount comes with extensive documentation. You can also read the documentation online thanks to Read the Docs.
