How to parse JSON object using JSON.stringify() in JavaScript ?

In this article, we will see how to parse a JSON object using the JSON.stringify function. The JSON.stringify() function is used for parsing JSON objects or converting them to strings, in both JavaScript and jQuery. We only need to pass the object as an argument to JSON.stringify() function.

Syntax:

JSON.stringify(object, replacer, space);

Parameter Values: This function accepts 3 parameters that are described below:

• object: It is the required value that is used to be parsed or converted to a string.
• replacer: To filter the result, a function or an array is used. If replacer is null or not given, the resultant JSON string contains all of the object’s properties. This is an optional parameter.
• space: This parameter controls the space in the final string created by the JSON.stringify() method. It can be either a number or a string. If this is a number, it denotes the number of white space characters to use for indenting; this value is limited to 10. If this is a string, the whole string or its first 10 characters is utilized as white space. No white space is used if this option is not given (null).

Return Value: A string representing the given value.

Example 1: In the below example, the JSON object is being passed as a value to the JSON.stringify() function to be parsed.

Javascript

<script>
    var obj = {
        name: "Vishal",
        email: "abc@gmail.com",
    };
    var result = JSON.stringify(obj);
    document.write("parsed object = " + result);
</script>

Output:

parsed object = {
    "name":"Vishal",
    "email":"abc@gmail.com"
}

Example 2: In the below example, the array is declared inside the object that is being passed as a value to the JSON.stringify() function to be parsed.

Javascript

<script>
    var obj = {
        company: "GeeksforGeeks",
        courses: ['DSA', 'Web Tech',
            'Placement_Preparation', 'DDA']
    };
    var result = JSON.stringify(obj);
    document.write("parsed object = " + result);
</script>

Output:

parsed object = {
    "company":"GeeksforGeeks",
    "courses":["DSA","Web Tech","Placement_Preparation","DDA"]
}
