JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate. It's the standard format for APIs and configuration files.

Example: {"name": "John", "age": 30, "city": "New York"}

❓ FAQ

What's the difference between format and minify?

Format (beautify) adds indentation and line breaks for readability. Minify removes all unnecessary whitespace to reduce file size for production use.

How do I fix JSON syntax errors?

Common errors include: missing commas between properties, trailing commas, unquoted keys, single quotes instead of double quotes. Our validator highlights the exact location of errors.

Is my JSON data secure?

Yes! All formatting happens in your browser. Your JSON data never leaves your device and is not stored or transmitted anywhere.

Can I format large JSON files?

Yes! Our tool can handle large JSON files. However, very large files (multiple MB) may take a moment to process depending on your device.
