JSON Formatter FAQ

What is a JSON formatter?

A JSON formatter is an online tool that takes raw or minified JSON data and formats it with proper indentation and line breaks, making it human-readable. It also validates JSON syntax to ensure the data structure is correct.

How do I validate JSON?

Simply paste your JSON code into the input field and click "Format JSON". If your JSON contains syntax errors, the tool will display an error message indicating what's wrong. Valid JSON will be formatted with proper indentation.

What's the difference between formatting and minifying JSON?

Formatting JSON adds indentation, line breaks, and spacing to make it readable. Minifying removes all unnecessary whitespace to reduce file size, which is useful for production environments and API responses.

Can I use this JSON formatter for large files?

Yes, this JSON formatter can handle large JSON files. All processing happens in your browser, so performance depends on your device's capabilities. For very large files (over 10MB), you may experience slower processing.

Is my JSON data secure?

Absolutely. This is a client-side JSON formatter, meaning all processing happens directly in your browser. Your JSON data never leaves your device or gets sent to any server.

What JSON formatting options are available?

This tool formats JSON with 2-space indentation, which is the standard for most projects. You can format to make JSON readable or minify to compress it for production use.
