Paste your JSON below. Format, validate, and minify instantly.
Paste any JSON into the input box on the left, then click Format to beautify it with proper indentation. Use Minify to compress it into a single line for production use. Validate checks your JSON for errors and shows the exact line and position of any problem.
Works with any valid JSON — API responses, config files, database exports, webhook payloads, and more. Nothing is sent to a server. All processing happens in your browser.
