Tips for effectively parsing extensive nested JSON structures?

JSON Data on PasteBin

I need assistance in converting this JSON data into an Object. It seems valid according to jsonlint, but I'm encountering issues with parsing it. Any help would be greatly appreciated.

"Data":[{...},{...},] // structured like this

Whenever I attempt the following:

JSON.parse(jsonparamter) <-- Uncaught SyntaxError: Unexpected token A in JSON at position 71
    at JSON.parse (<anonymous>)
    at <anonymous>:1:6

javascript json

To effectively decode JSON encoded data with multiple levels, you will need to implement a loop to access the nested elements within the JSON structure. Take a look at the following code snippet for an illustration of how to retrieve Data.Address.Value from this dictionary:

// Define URLs and headers for making HTTP requests
corsurl = 'https://cors-anywhere.herokuapp.com/'
jsonurl = 'https://pastebin.com/raw/vuecweML'
headerNames = ['Content-Type', 'Accept']
headerValues = ['application/json', 'application/json']

// Modular function for performing GET requests
function getRequest(baseRestURL, APIPath, headerNames, headerValues, callback) {
  var completeRestURL = baseRestURL + APIPath;
  console.log('REST API URL: ' + completeRestURL);
  var method = 'GET';
  var url = completeRestURL;
  var async = true;
  var request2 = new XMLHttpRequest();
  
  request2.onload = function () {
    console.log('ONLOAD');
    var status = request2.status;
    console.log(status);
    console.log(request2.responseText);
    var response = request2.responseText;
    return callback(response);
  }
  
  request2.open(method, url, async);
  
  for (var i in headerNames) {
    request2.setRequestHeader(headerNames[i], headerValues[i]);
  }
  
  request2.send(null);
}

// Segment of interest
getRequest(corsurl, jsonurl, headerNames, headerValues, response => {

  parsed = JSON.parse(response).Data; 
  objects = JSON.parse(parsed); 
  selection = JSON.parse(objects[0].Address)[0].Value; 
  document.getElementById('result').innerHTML = selection; 
 })
