Have you ever tried to edit or read a JSON data and got lost in the maze of brackets, quotes, and no structure? We will present something perfect to the above-said. Our Open Source JSON with Line Numbers and Formatting is an online, easy to use, clean, and powerful JSON editor, minifier, JSON pretty printing, validator, and formatter.

JSON Editor with Line Numbers & Formatting

This editor has made everything simple whether you are a newbie to the working of JSON or a developer using APIs.

What is JSON and Why Do You Need an Editor?

Why don’t we make it easy? JSON (JavaScript Object Notation) is a data format that is used to store and exchange information. It is the language of nearly all apps, websites, or tools based on APIs.

Here’s a tiny example of JSON:

{

  “name”: “John”,

  “age”: 30

}

Looks small, right? But imagine you’re working with thousands of lines of nested JSON without formatting, without line numbers, and no idea where your error is. Nightmare.

That’s where our JSON Editor becomes your best friend.

What Can This Free JSON Editor Do?

Our tool is designed to solve real-world problems for developers, data analysts, testers, and even beginners. Here’s what it offers:

Format JSON with One Click: Messy JSON? Just paste your code and hit “Format JSON”. Instantly, your data gets beautified with proper indentation, line breaks, and spacing.

Minify JSON for Fast Loading: Need a compact version? Use the “Minify JSON” button to strip out unnecessary spaces and line breaks. This is great for reducing file size before saving or sending data.

Live Line Numbers: Reading long JSON files is easier when you can see what line you’re on. Our editor adds live line numbers beside your code. No more counting lines manually.

Toggle Line Numbers On/Off: Don’t like line numbers? You can turn them off anytime using the “Toggle Line Numbers” button. The choice is yours.

Real-Time JSON Validation: Paste some JSON, and we’ll instantly tell you if it’s valid or broken. If there’s an error, we’ll show exactly where and what the issue is.

Clear JSON Instantly: Want a fresh start? Use the “Clear” button to wipe everything clean. Perfect when you want to test new JSON structures quickly.
