If you are using npm package manager you can do it via file-saver. Just do installation of file-saver package :

npm install file-saver --save

Then import file-saver accordingly:

import { saveAs } from 'file-saver';

const jsonObject: any = [{name : "sheldon", age : "10"}, {name : "Simon", age : "11"}];

const blob = new Blob([JSON.stringify(jsonObject)], {type : 'application/json'});
saveAs(blob, 'demo.json');

Keep in mind that web browser doesnt have the permission to write content to specified location. Instead what you can do is that you can create the File object in the browser iteself and download it accordingly. If it is a web browser it will be downloaded to your default downloading location. I'm providing a Angular based solution here since you have mentioned angular in your question.
