Convert Javascript JSON Object to JSON String

You can use the javascript JSON.stringify() method, which is used to convert an object a JSON string.

Syntax:

JSON.stringify(value[, replacer[, space]]);
  • value:- It’s a required parameter and converts to JSON string.
  • replacer:- it is an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings.
  • space: It is also an optional parameter. This argument is used to control spacing in the final string generated using JSON.stringify() function.

Ex1: Convert Object to JSON String JavaScript

Here we have one JSON object and we will convert the JSON objects to JSON strings in javascript. Let’s see the example below:

  name: 'Developer',
  age: 25,
  favoriteColor: 'Black'
};

var myObjStr = JSON.stringify(myObj);

document.write('Result of the above code is:-' + myObjStr);

Result of the above code is:-{“name”:”Developer”,”age”:25,”favoriteColor”:”Black”}

Ex2: convert any date objects into strings

Now, we will take the example of convert any date objects into strings using the JSON.stringify() method:

var myObj = {
  name: 'Developer',
  age: 25,
  favoriteColor: 'Black',
  today: new Date(),
};

var myObjStr = JSON.stringify(myObj);

document.write('Result of the above code is:-' + myObjStr);

Result of the above code is:-{“name”:”Developer”,”age”:25,”favoriteColor”:”Black”,”today”:”2019-12-09T13:37:17.307Z”}
