Thankyou It really helped me a lot.

module.exports = function() {
const data = require("./testdata.json");

const jsonData = JSON.parse(data).studentData.map((element) => {
const name = element.Name;
const aggregate = parseInt(element.aggregate);
const percentages = element.percentages.map((per) => {
const sub1 = parseInt(per.sub1);
const sub2 = parseInt(per.sub2);
const sub3 = parseInt(per.sub3);
return { sub1, sub2, sub3 };
});

return { name, aggregate, percentages };

});

return { studentData: jsonData };
};

loopObject.js
const fs = require('fs');

const foodItems = JSON.parse(fs.readFileSync('./data.json'));

foodItems.forEach((item, index) => {
// Modify the data as per your wish
item.Name += " (Modified)";
item.price += 2.0;
});

console.log(foodItems);
