JSON Formatter

JSON Formatter – Beautify, Format & Validate JSON Easily

When you're working with messy or minified JSON data, it becomes incredibly difficult to read, debug, or share with others. Our JSON Formatter is built to solve that problem—instantly formatting your JSON code into a clean, indented, and human-readable structure.

Whether you’re building APIs, working with third-party data, or debugging app responses, our free JSON formatter is your go-to tool for clarity and efficiency.

What Is a JSON Formatter?

A JSON Formatter is an online tool that automatically formats and indents your raw or minified JSON data. It transforms flat, hard-to-read strings into a readable tree structure or pretty-printed output.

For example:

Minified JSON:

{"id":1,"name":"John","skills":["JavaScript","Python"]}

Formatted Output:

{
  "id": 1,
  "name": "John",
  "skills": [
    "JavaScript",
    "Python"
  ]
}

This makes your data far easier to read and work with.

💻 API Debugging

Most APIs return JSON responses in minified form. Formatting it makes the structure visible and errors easier to find.

Working with package.json, manifest.json, or other config files? Format them first to avoid mistakes.

📊 Data Analysis

View structured data outputs from databases or applications clearly.

🧪 Automation & Testing

When crafting test payloads or checking test results, formatted JSON makes life easier.

Real-Life Example: Before and After

Before (Minified):

{"user":{"id":101,"name":"Alice","roles":["admin","editor"]},"active":true}

After (Formatted):

{
  "user": {
    "id": 101,
    "name": "Alice",
    "roles": [
      "admin",
      "editor"
    ]
  },
  "active": true
}

With our JSON Formatter, you gain a clearer view, spot errors faster, and communicate your data more effectively.
