A tool for formatting JSON files

JFormat

A command-line tool for formatting and prettifying JSON files with customizable sorting options.

Quick Start

# Install the package
pip install jformat

# Format a JSON file
echo '{"b":1,"a":2}' > input.json
jformat input.json

Features

• Pretty print JSON with proper indentation
• Optional sorting of JSON keys
• Simple command-line interface
• Support for large JSON files
• Preserves JSON data types

Installation

You can install JFormat using pip:

pip install jformat

For development installation:

git clone https://github.com/hwang2006/jformat.git
cd jformat
pip install -e .

Usage

Basic usage:

# Format with default settings (sorted keys)
jformat input.json

# Format without sorting keys
jformat --no-sort input.json

Options

• --sort / --no-sort: Enable or disable sorting of JSON keys (default: --sort)
• FILE_PATH: Path to the JSON file to format

Examples

1. Format a JSON file with sorted keys:

jformat examples/input.json

Input:

{"b": 1,"a": 2,"c": {"z": 3,"y": 4}}

Output:

{
    "a": 2,
    "b": 1,
    "c": {
        "y": 4,
        "z": 3
    }
}

2. Format without sorting keys (preserves original order):

jformat --no-sort examples/input.json
