I assume you want the answer in javascript which is implicitly on your tags. Here is how you do it using javascript

var jsonFile = `{
  "version": "0.3.4.0",
  "url": "",
    "productSources": {
        "ps": ""
    }
}`;
var url = "C:\\Users\\yw1kew\\AppData\\Local\\dmv\\dmv.data\\cameraApp";
var jsonObject = JSON.parse(jsonFile);
jsonObject.url = url;
var jsonString = JSON.stringify(jsonObject);

Where jsonString is the final string with the path in it.
