javascript object to json code example

Example 1: turn object into string javascript

var obj = {a: "a", b: "b" /*...*/};
var string = JSON.stringify(obj);
// OUTPUT:
// "{'a':'a', 'b':'b'}"

Example 2: js print object as json

var obj = {
  a: 1,
  b: 2,
  c: { d: 3, e: 4 } // object in object
};

// method 1 - simple output
console.log(JSON.stringify(obj)); // {"a":1,"b":2,"c":{"d":3,"e":4}}

// method 2 - more readable output
console.log(JSON.stringify(obj, null, 2)); // 2 - indent spaces. Output below
/*
{
  "a": 1,
  "b": 2,
  "c": {
    "d": 3,
    "e": 4
  }
}
*/

var obj = {name: "Martin", age: 30, country: "United States"};
 
// Converting JS object to JSON string
var json = JSON.stringify(obj);
 
console.log(json);
