In this post, we will see how to pretty print JSON in Python.<\/p>\n

We can use the Python JSON module to pretty-print JSON data. We can use json’s dumps()<\/code> method with indent<\/code> parameter to pretty print json data.

Python pretty print json string<\/h2>\n

Let’s understand this with the help of example.<\/p>\n

\nimport json\n\njson_countries = '[{\"ID\":101,\"Name\":\"India\",\"Population\":\"20000\"},' \\\n            '{\"ID\":201,\"Name\":\"Bhutan\",\"Population\":\"3000\"}]'\n\njson_obj_countries = json.loads(json_countries)\n\njson_pretty_str = json.dumps(json_obj_countries, indent=2)\n\nprint(json_pretty_str)\n<\/pre>\n
Output:<\/strong><\/p>\n
\n[
\n  {
\n    “ID”: 101,
\n    “Name”: “India”,
\n    “Population”: “20000”
\n  },
\n  {
\n    “ID”: 201,
\n    “Name”: “Bhutan”,
\n    “Population”: “3000”
\n  }
\n]\n<\/div>\n
Explanation<\/strong><\/p>\n
    \n
  1. Import json module<\/li>\n
  2. Use json’s loads()<\/code> method to convert json string json_countries<\/code> to json object json_obj_countries<\/code><\/li>\n
  3. Use json’s dumps()<\/code> method to convert json object json_obj_countries<\/code> to pretty print json data string json_pretty_str<\/code><\/li>\n
  4. Print the string json_pretty_str<\/code><\/li>\n<\/ol>\n
    Python pretty print json File<\/h2>\n
    We can first read json file into string<\/a> with open()<\/code> function
    \nLet’s understand this with the help of example.
    \nHere is json file which we are going to read.<\/p>\n
    \"EmployeesJsonFile\"<\/p>\n
    \nimport json\n\nwith open('Employees.json', 'r') as json_file:\n    json_obj_countries = json.load(json_file)\n\nprint(json_obj_countries)\nprint(\"========================================\")\njson_pretty_str = json.dumps(json_obj_countries, indent=2)\nprint(json_pretty_str)\n<\/pre>\n
    Output:<\/strong><\/p>\n
    \n[{‘Employee ID’: 101, ‘Employee Name’: ‘Arpit’, ‘Age’: ’24’}, {‘Employee ID’: 202, ‘Employee Name’: ‘John’, ‘Age’: ’30’}]
    \n========================================
    \n[
    \n  {
    \n    “Employee ID”: 101,
    \n    “Employee Name”: “Arpit”,
    \n    “Age”: “24”
    \n  },
    \n  {
    \n    “Employee ID”: 202,
    \n    “Employee Name”: “John”,
    \n    “Age”: “30”
    \n  }
    \n]\n<\/div>\n
    Explanation<\/strong><\/p>\n
      \n
    1. Import json module<\/li>\n
    2. Use open(‘Employees.json’, ‘r’) function to read file into json_file<\/code><\/li>\n
    3. Use json’s load()<\/code> method to convert file object json_file<\/code> to json object json_obj_countries<\/code><\/li>\n
    4. Use json’s dumps()<\/code> method to convert json object json_obj_countries<\/code> to pretty print json data string json_pretty_str<\/code><\/li>\n
    5. Print the string json_pretty_str<\/code><\/li>\n<\/ol>\n
      You can use indent=$space<\/code> with dumps to pretty print json string.<\/p>\n
      For example:
      \njson_pretty_str = json.dumps(json_obj_countries, indent=2)<\/code> will output as:<\/p>\n
      \n[\n  {\n    \"Employee ID\": 101,\n    \"Employee Name\": \"Arpit\",\n    \"Age\": \"24\"\n  },\n  {\n    \"Employee ID\": 202,\n    \"Employee Name\": \"John\",\n    \"Age\": \"30\"\n  }\n]\n<\/pre>\n
      whereas, json_pretty_str = json.dumps(json_obj_countries, indent=4)<\/code> will output as:<\/p>\n
      \n[\n    {\n        \"Employee ID\": 101,\n        \"Employee Name\": \"Arpit\",\n        \"Age\": \"24\"\n    },\n    {\n        \"Employee ID\": 202,\n        \"Employee Name\": \"John\",\n        \"Age\": \"30\"\n    }\n]\n<\/pre>\n
