How to style/format JSON response and display it in user readable format?

I’m working on a personal project , A postman clone.
I’m using fetch API to fetch the data and then using JSON.stringify() to convert that into string and display it inside a "textarea" which is the "Response" field as you can see below.
Came across an answer- , but it doesn’t seems to work for me.

How can I format the json object or the string and display it inside the "Response" tab ?

PostMan Response

**Here is the html code for the response field**
<div class="responseBox">
    <textarea class="responseText" id="responseId" ></textarea>

**JS code for fetching the response using Fetch API and displaying it in Response field :** 
const response = await fetch(url);
console.log("Fetching data...");
const e = await response.json();

**CSS for response field :** 
width: 705px;
height: 350px;
position: relative;
right: 255px;
white-space: pre;


>Solution :

As the answer you have linked suggests, the JSON.stringify function supports formatting JSON strings, which is how you should format JSON strings.

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level
