Answer 2

This is the received json, in the form of a JS object.
Run through the object and get the data you need:

function saveData(response) {
  const data = response;
  console.log(data); 

  for( var prop in data) {
    console.log(data[prop], data[prop]['descrName']); //и т.д.
  }
}

if you need to convert a string to json, then use json.parse

var jsonData = {};
try {
  jsonData = JSON.parse(inputStr);
} catch (e) {
  // обработать ошибку парсинга
}
