About this tool
JSON Formatter beautifies messy or minified JSON with proper indentation and color-coded syntax, so API responses and config files are easy to read. Use Minify to compress JSON down to a single line for production, or Validate to catch syntax errors with a precise message. All processing happens entirely on your device — your data is never sent anywhere.
