Translate Ledger CLI query syntax into BQL

ledger2bql

Translate Ledger CLI query syntax into BQL

Implemented in Python.

The package is available at https://pypi.org/project/ledger2bql/.

Introduction

BQL is quite a powerful language for slicing and dicing Beancount data. But, when all you need are simple queries, writing every field and filter seems tedios. In comparison, Ledger CLI's syntax is short and efficient. A simple l b bank will list all bank accounts, assuming a well-organized account tree.

The purpose of this project, a simple CLI utility, is to accept a Ledger-like syntax, generate an appropriate BQL statement, and run it for you.

Development

Setup

Clone the repository. Add an .env file, specifying the BEANCOUNT_FILE location.

BEANCOUNT_FILE=tests/sample_ledger.bean

uv sync

Build

uv build

Run

uv run ledger2bql

or run

l ...

Tests

Since the app is using .env file for environment variables, make sure that BEANCOUNT_FILE is set to the sample_ledger.bean in the tests/ directory.

Usage

Install the package:

uv pip install ledger2bql
# or
uv tool install ledger2bql

Set the BEANCOUNT_FILE variable to point to your Beancount ledger file. You can create an .env file, to customize different ledgers for different folders.

Run

ledger2bql b card
ledger2bql r card -b 2025-08-01

To get the list of available parameters, simply run

ledger2bql
ledger2bql bal --help
ledger2bql reg --help

Output

Balance

Running

l b

will output

Your BQL query is:

SELECT account, sum(position) GROUP BY account ORDER BY account ASC

+--------------------------+---------------+
