{"SubmitBy":"SK", "Students[0].name":"Jhon", "Students[0].age":"15", "Students[1].name":"Sam", "Students[1].age":"16", "Students[2].name":"Tom", "Students[2].age":15}

Result expecting like this

{SubmitBy:"SK", Students:[{name:"Jhon", age:"15"},{name:"Sam", age:"16"},{name:"Tom", age:"15"} ]}

You can use library like dot-prop to achieve this, code below:

import { setProperty } from 'dot-prop';

const input = {
  SubmitBy: 'SK',
  'Students[0].name': 'Jhon',
  'Students[0].age': '15',
  'Students[1].name': 'Sam',
  'Students[1].age': '16',
  'Students[2].name': 'Tom',
  'Students[2].age': 15
};
const output = {};

for (const [key, value] of Object.entries(input)) {
  setProperty(output, key, value);
}
console.log(output);

const originalData = {"SubmitBy":"SK", "Students[0].name":"Jhon", "Students[0].age":"15", "Students[1].name":"Sam", "Students[1].age":"16", "Students[2].name":"Tom", "Students[2].age":15};

const transformedData = { SubmitBy: originalData.SubmitBy, Students: [] };

for (let i = 0; i < 3; i++) {
  const student = {
    name: originalData[`Students[${i}].name`],
    age: originalData[`Students[${i}].age`].toString(),
  };
  transformedData.Students.push(student);
}

console.log(transformedData);
