To dump a Python object to JSON string, you can use the json.dumps() method of the built-in json module. The json.dump() paired method (without the "s") converts the Python object to JSON string and writes it to a file. By passing indent and sort_keys parameters to the json.dumps() and json.dump() methods, you can pretty-print the result JSON, otherwise, a compact JSON will be generated. If your Python object contains a non-basic objects, the json.dumps() method will throw an exception. By passing the skipkeys=True, you can tell json.dumps() to ignore such objects instead of throwing an exception. In this Python JSON Dumps example, we are serializing a basic Python object to a JSON string. More advanced Python to JSON examples are listed below.

How to parse a JSON with Python?
To parse a JSON data string to a Python object, use the json.loads() method of the built-in package named json. The json.loads() method parses the provided JSON data string and returns a Python dictionary containing all the data from the JSON. You can get parsed data from this Python dictionary by referring to objects by names or, starting from Python 3.7, by indexes. Nested JSON objects will also be processed and included in the dictionary (see example below). To parse a JSON file, use the json.load() paired method (without the "s"). In this Python Parse JSON example, we convert a JSON data string into a Python object. Click Execute to run the Python Parse JSON example online and see the result.
How do I pretty print JSON in JavaScript?
To pretty-print JSON in JavaScript, you can use the JSON.stringify(obj, replacer, space) method. The third parameter of the JSON.stringify() method specifies the number of spaces to use when outputting the JSON string. If you pass a non-zero number, JSON.stringify() will generate pretty JSON with the specified number of white spaces in the JSON. If you pass 0, then JSON.stringify() will generate minified JSON. You can also pass a string instead of a number, which will be inserted instead of spaces. In this JavaScript Pretty Print JSON example, we use the JSON.stringify() method to print a JavaScript object in a human-readable format.

How do I pretty print JSON in Python?
To pretty print a JSON string in Python, you can use the json.dumps(indent) method of the built-in package named json. First, you need to use the json.loads() method to convert the JSON string into a Python object. Then you need to use json.dumps() to convert the Python object back to JSON. The json.dumps() method takes a number of parameters, including the "indent" level for the JSON arrays, which will be used to pretty-print the JSON string. If the json.dumps() indentation parameter is negative 0, or an empty string, then there is no indentation, and only newlines are inserted. By default, the data is printed as a single-line JSON string without indentation. In this Python Pretty Print JSON example, we load a minified JSON string and pretty print it using json.dumps() method.
