About the JSON Formatter & Validator

Working with JSON (JavaScript Object Notation) is a daily task for developers. However, JSON data from APIs or logs is often minified (on a single line) or poorly formatted, making it extremely difficult to read and debug. Our JSON Formatter & Validator tool solves this problem instantly.

Simply paste your JSON text into the input field. Our tool will immediately parse and validate it. If the JSON is invalid, it will report the syntax error so you can fix it. If it's valid, you can:

Format / Beautify: Converts messy JSON into a perfectly indented, human-readable format.
Minify: Compresses the JSON into a single line, which is useful for production or sending in API requests.

This tool runs 100% in your browser. Your data is never sent to a server, ensuring it remains fast, secure, and private.
