JSON pretty print multiple lines

Question

which command line utility can pretty-print a file with multiple lines (each encoded in json)

input file: msgs.json:

[1,{"6":7,"4":5}]
[2,{"6":7,"4":5}]

it seems that json.tool works only with a single JSON message

EDIT: modified json.tool to support multiple JSON msgs in the answer below

example usage:

python myjson.py msgs.json
                    [
                        1,
                        {
                            "4": 5,
                            "6": 7
                        }
                    ]
                    [
                        2,
                        {
                            "4": 5,
                            "6": 7
                        }
                    ]

Answer 1

In python do something like this:

import json

with open('msgs.json', 'r') as json_file:
    for row in json_file:
        data = json.loads(row)
        print(json.dumps(data, sort_keys=True, indent=2, separators=(',', ': ')))
