Online JSON Formatter & Validator - Clean Your Code

Working with messy, minified JSON data? Our JSON formatter is the ultimate tool for developers. It takes raw JSON strings and transforms them into a beautifully indented, human-readable format. It also validates your JSON to ensure it's syntactically correct.

Why Use a JSON Formatter?

JSON is the standard for data exchange on the web, but it's often delivered in a compact, unreadable format. Our free JSON beautifier helps you debug APIs, inspect data structures, and prepare code for documentation with ease.

Top Features:

• Syntax Highlighting: Easily distinguish between keys, values, and structures.
• Instant Validation: Catch missing commas or brackets immediately.
• Custom Indentation: Choose between 2 or 4 spaces for your preferred style.
• Local Processing: Your data stays in your browser, perfect for sensitive API keys or user data.

How to Format JSON

1. Paste your raw JSON into the input box.
2. Click "Format JSON" to beautify the code.
3. Review any syntax errors if the validation fails.
4. Copy the formatted JSON to your clipboard.
