JSON Formatter for Python

import json

data = {"name": "John", "age": 30, "roles": ["admin", "user"]}

# indent=2 adds readable indentation
formatted = json.dumps(data, indent=2)
print(formatted)

import json

formatted = json.dumps(
    data,
    indent=4,
    sort_keys=True,
    ensure_ascii=False,  # keep accented characters as-is
)
print(formatted)

# Python ships with a built-in JSON tool
python -m json.tool input.json output.json

# Or pretty print to the terminal
cat input.json | python -m json.tool
