JSON Formatter

Format, minify and validate JSON. Instantly highlights errors.

A JSON Formatter takes raw, unreadable JSON data and restructures it with proper indentation and line breaks, making it easy to read and debug. It also validates your JSON in real time — instantly telling you if there's a syntax error and exactly where it is. JSON (JavaScript Object Notation) is the most widely used data format for APIs, config files, and databases. Whether you're debugging an API response or cleaning up a config file, a JSON formatter is one of the most-used tools in any developer's workflow.

How to use:

• 1. Paste your raw JSON into the input box on the left
• 2. Click Format to pretty-print it with indentation
• 3. Click Minify to compress it into a single line
• 4. If there's an error, the validator will highlight exactly what's wrong
• 5. Click Copy to grab the output
