Assume you have some data where everything is string and it represents as below: 

You have to format and return the data as below:

Basically, after getting the data you have to change Data-types and return the required JSON.

Note: 

• Have a look at JSON data before writing the code
• All the code should be written in "tindex.js" file
• Select Run -> install to install the dependencies.

module.exports= function(){

 

const data = require("./testdata.json");

/*Explore the JSON file and return required JSON data*/

var json = JSON.parse(data).studentData;

json.forEach(function(element, index){

  element['aggregate'] = parseInt(element['aggregate']);

  element.forEach(function(per,ind){

    per['sub1'] = parseInt(per['sub1']);

    per['sub2'] = parseInt(per['sub2']);

    per['sub3'] = parseInt(per['sub3']);

});

});
