Format, Validate, and Minify JSON Online
The CodeSnap JSON Formatter helps developers clean up API responses, configuration files, logs, and pasted JSON payloads. It parses the input in the browser, reports syntax errors, and produces readable formatted JSON with two-space indentation.
Use the minifier when you need compact JSON for tests, embeds, or transport payloads. The copy action keeps the formatted or minified result ready for code reviews, documentation, and debugging sessions.
