Free JSON Formatter & Validator Online – Beautify & Validate JSON Instantly

If you work with APIs or JavaScript, you’ve probably encountered messy, hard-to-read JSON files.

Manually fixing indentation or finding missing commas is both frustrating and time-consuming.

That’s why I built JSON Toolaska – a free, fast, and easy-to-use JSON Formatter & Validator that works right in your browser.

🚀 Why Use JSON Toolaska?

Instant Formatting – Paste your JSON and get a clean, pretty version in one click.
Error Validation – Detects and highlights syntax errors in real-time.
No Sign-Up Required – Use it instantly, without creating an account.
Lightweight & Fast – Runs completely in your browser.
No Ads, No Distractions – Just focus on your JSON.

💡 Example: From Messy to Readable

Here’s a typical unformatted JSON:

{"name":"John","age":30,"city":"New York","skills":["JavaScript","Node.js","React"]}

After running it through json.toolaska.com, you get:

{
  "name": "John",
  "age": 30,
  "city": "New York",
  "skills": [
    "JavaScript",
    "Node.js",
    "React"
  ]
}
