And just get the ID
is there anyway to look for the name and get the ID back? (the id is the 0005000010105A00)
thanks!

    I’m going to make a few assumptions to try to help you.

    First, I’m guessing you have an object like this:

    {
  "GB": {
    ...
  }
}

    where each entry in the "GB" object is an object with the form you described.

    If so, here’s how I would select the object you provided and return it’s "id" (typically called a "key" in the JavaScript community).

    // Get your json data from somewhere like a file or URL and parse it into an object.
let myObject = JSON.parse(myJsonData);

// Create our id variable.  If we don't find the desired name, id will be undefined.
function getId (name) {
  let id;
  Object.entries(myObject.GB).forEach(([key,obj]) => {
    if (obj.name === name) {
      id = key;
    }
  });
  return id;
}

// now netflixId will be the desired id, or undefined if there's no such name found.
let netflixId = getId('Netflix');

    I hope that helps.

    For future reference, you’ll do better posting what you’ve tried already.

    If your JSON is in a .json file, you can access it in code with require:

    const filename = 'your-file-name'
const data = require(filename)

    Then use Sir Robert’s answer to get the ID, or install and then use the very popular lodash library’s get function:

    const _ = require('lodash')

const filename = 'your-file-name'
const data = require(filename)

const netflixId = _.get(data, 'ID')
