python3 之格式化json

2024-08-22 23:03:23

import json

json_string = None

with open("json_file.json") as f:

    json_string = f.read()

try:

    parsed_json = json.loads(json_string)

    formatted_json = json.dumps(parsed_json, indent = 4,sort_keys=True)

    with open("json_file.json","w") as f:

        f.write(formatted_json)

except Exception as e:

    print(repr(e))

Parameter indent decides the number of spaces to use for indentation.

Parameter sort_keys decides whether the keys in formatted JSON should be in sorted order or not. Default value is False.

Bonus: You can pretty-print the small JSON string directly at command terminal without using python script file. Use below line of code.

echo '{"first_name": "Anurag", "last_name": "rana"}' | python -m json.tool
