Online JSON Formatter, Validator & Minifier
Paste messy or minified JSON to instantly beautify, validate syntax with error reporting, and minify for production APIs.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format readable by both humans and machines. It is the standard format for REST API responses, configuration files, and database records in modern web development.
When to Use This Tool
Beautify — Paste a minified or compressed API response to make it human-readable with indentation and line breaks.
Minify — Compress formatted JSON into a single line for smaller HTTP response payloads and faster API performance.
Validate — Instantly see if your JSON has syntax errors, unclosed brackets, or trailing commas before sending it to an API.
