Parse JSON string inside of a object

Question

I am trying to parse a json string inside of a JSON object but continue getting "Unexpected Token" Or "unexpected end of input" errors. Any help would be greatly appreciated!

The syntax looks like so:

{
  full_name: 'John Doe',
  company_name: 'TEST',
  sample: 't-e-s-t',
  populated: '{"type":"Select","manualTitle":"Manual Title","manualBody":"Email Message will go here","templateTitle":"Title Here","templateBody":"Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old."}',
  messageBody: 'New body test'
}

That's a JS object, not a JSON object. (Thepopulated property is JSON) — Quentin

@Kinglish OP calls their object literal a "JSON object" (which is a term without any right to exist). But yes, it works fine: jsfiddle.net/2mqxr0kn — user5734311

That's a JavaScript object, not JSON. (JSON is a string and has a very specific syntax.) So use JSON.parse to parse the value of the populated property of the object, and then you can extract its keys and values.

const obj = {
  full_name: 'John Doe',
  company_name: 'TEST',
  sample: 't-e-s-t',
  populated: '{"type":"Select","manualTitle":"Manual Title","manualBody":"Email Message will go here","templateTitle":"Title Here","templateBody":"Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old."}',
  messageBody: 'New body test'
};

const populated = JSON.parse(obj.populated);
console.log(populated.manualBody);
