JSON Formatter/Validator

Clean, validate, and beautify your JSON code instantly with our Free JSON Formatter. Whether you are debugging an API response, configuring a server file, or just trying to read a minified JSON string, this tool makes it easy.

Why Use This JSON Tool?

• Instant Validation: Automatically detects errors in your syntax and tells you exactly where the problem is.

• Beautify & Minify: Convert ugly, minified one-liners into readable, indented code (Pretty Print) or compress it back down to save space.

• Secure & Client-Side: Your data never leaves your browser. All formatting happens locally on your machine, so your API keys and private data remain safe.
