We can use the Python json module to pretty-print the JSON data. The json
module is recommended to work with JSON files. We can use the dumps()
method to get the pretty formatted JSON string.
import json
json_data = '[{"ID":10,"Name":"Pankaj","Role":"CEO"},' \
'{"ID":20,"Name":"David Lee","Role":"Editor"}]'
json_object = json.loads(json_data)
json_formatted_str = json.dumps(json_object, indent=2)
print(json_formatted_str)
Output:
[
{
"ID": 10,
"Name": "Pankaj",
"Role": "CEO"
},
{
"ID": 20,
"Name": "David Lee",
"Role": "Editor"
}
]
json.loads()
to create the JSON object from the JSON string.json.dumps()
method takes the JSON object and returns a JSON formatted string. The indent
parameter defines the indent level for the formatted string.Let’s see what happens when we try to print a JSON file data. The file data is saved in a pretty printed format.
import json
with open('Cars.json', 'r') as json_file:
json_object = json.load(json_file)
print(json_object)
print(json.dumps(json_object))
print(json.dumps(json_object, indent=1))
Output:
[{'Car Name': 'Honda City', 'Car Model': 'City', 'Car Maker': 'Honda', 'Car Price': '20,000 USD'}, {'Car Name': 'Bugatti Chiron', 'Car Model': 'Chiron', 'Car Maker': 'Bugatti', 'Car Price': '3 Million USD'}]
[{"Car Name": "Honda City", "Car Model": "City", "Car Maker": "Honda", "Car Price": "20,000 USD"}, {"Car Name": "Bugatti Chiron", "Car Model": "Chiron", "Car Maker": "Bugatti", "Car Price": "3 Million USD"}]
[
{
"Car Name": "Honda City",
"Car Model": "City",
"Car Maker": "Honda",
"Car Price": "20,000 USD"
},
{
"Car Name": "Bugatti Chiron",
"Car Model": "Chiron",
"Car Maker": "Bugatti",
"Car Price": "3 Million USD"
}
]
It’s clear from the output that we have to pass the indent value to get the JSON data into a pretty printed format.
