Working with JSON in Javascript

JSON is a very popular format in programming and support by most of modern languages. In Javascript, it natively supports JSON.

Parse JSON text to Javascript object

We have a variable assigned to this JSON text.

 var jsonin = '{"employees":[
  {"firstName":"Config9", "lastName":"COM"},
  {"firstName":"Inneka", "lastName":"COM"},
  {"firstName":"oraerr", "lastName":"COM"}

Now use JSON.parse() with this text

var jsonobj = JSON.parse(jsonin);

Now we have an object, we can access elements in this object as normal.


Dump JSON object to text output

we can use JSON.stringify() method to dump JSON object as follow:

var jsontxt = JSON.stringify(jsonobj, undefined, 4);

Happy coding!
