I'm not sure if you want to be able to do this locally (i.e., so the user can download a JSON file), or if you want to do this using Node.js, so here's both approaches.

I mention Nodejs since you tagged this with Angular.

If you are using NodeJS, you can use the fs module:

let json = {"foo": "bar"};
let str = JSON.stringify(json);

let fs = require("fs");
fs.writeFile("jsonFile.json", str, function(error) {
    if (error) {
        console.log("Error");
    } else {
        console.log("Success");
    }
);

But if you want to create a file from the browser and download on the client machine:

let json = {"foo": "bar"};
let str = JSON.stringify(json);

let str = "data:text/json;charset=utf-8," + encodeURIComponent(str);
let dl = document.createElement("a");
dl.setAttribute("href", str);
dl.setAttribute("download", "jsonFile.json");
dl.click();

Also, your code did not get added to your question.
