JSON Formatter

The JSON Formatter is a client-side tool that takes unformatted or minified JSON data and formats it with proper indentation, spacing, and line breaks. It's an essential tool for developers who frequently work with API responses, configuration files, and data transfer objects.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard.

Despite its name, JSON is language-independent. Most modern programming languages have built-in support for parsing and generating JSON data.

JSON Syntax Example

{
  "name": "Jane Doe",
  "age": 30,
  "isDeveloper": true,
  "skills": ["JavaScript", "React", "Node.js"],
  "address": {
    "city": "San Francisco",
    "country": "USA"
  }
}

How to use

1. Paste your raw JSON data into the input field on the left.
2. Select your preferred indentation style (2 spaces, 4 spaces, or tabs).
3. Click the "Format" button to process your data.
4. If your JSON is valid, the formatted output will appear on the right side. You can quickly copy it using the copy icon.
5. If your JSON contains syntax errors, a descriptive error message will be shown to help you locate the issue.
