I'm trying to print a json string in a json format.

So, the input would be something like: "{\"a": 1, \"b\":\"2\"}"

I need the output to look like this:

{
  "a":1,
  "b":"2"
}

I have tried using JSON.stringify but it just prints out the same string. Any help is appreciated.

  • What is the different? `\` is an escape char. – Alen.Toma Mar 21 '22 at 18:52

    JSON is only ever a string. Other than not having a space between `"a":` and `1` (yeah... don't), you *could* parse to a JavaScript object, then stringify and give it a parameter to tell it to indent. – crashmstr Mar 21 '22 at 18:54

  • While re-reading the question, I figured that [this old question](https://stackoverflow.com/q/4810841/1218980) would fit more than the one I suggested above. – Emile Bergeron Mar 21 '22 at 18:58

Parse your string to js object, than parse it to string to with new lines.

console.log(JSON.stringify(JSON.parse('{\"a": 1, \"b\":\"2\"}'), null, 2));

Before just running below code you should make a small change.

"{\"a": 1, \"b\":\"2\"}" ->
"{\"a\": 1, \"b\":\"2\"}"

const stringifiedJson = "{\"a\": 1, \"b\":\"2\"}";
const result = JSON.parse(json);
console.log(result);
