What is "beautifying" JSON and why do I need it?

Beautifying adds indentation, line breaks, and proper formatting to make JSON readable and easy to debug. Minified JSON becomes 1 long line—beautifying makes it human-readable. Use for development, debugging, and code review. Verify by comparing readability before/after.

Does the tool validate and detect JSON errors?

Yes! The tool validates JSON syntax and highlights errors. Shows exact line and column of syntax problems with helpful error messages. Perfect for debugging malformed JSON from APIs, logs, or config files.

Can I minify/compress JSON to reduce file size?

Yes! Click "Minify" to remove all formatting, whitespace, and line breaks. Reduces JSON file size by 10-30% without changing data. Used in production APIs and web apps for faster transmission. Verify minified JSON still works with parsers.

Does the tool support all JSON data types?

Yes! Handles strings, numbers, booleans, null, arrays, and nested objects. Escapes special characters properly. Works with complex hierarchical JSON from APIs, databases, and configuration files. Size limit depends on browser memory.

Is my JSON data secure and private?

Yes, 100% private! All processing happens locally in your browser—JSON never uploads to servers. Perfect for processing sensitive API responses, API keys, credentials, and confidential data. Verify by checking browser dev tools (zero network requests).
