JSON Beautifier Guide

Use JSON Beautifier to clean up messy JSON, validate it, and switch between pretty and minified views without losing your place.

Quick steps

  1. Paste JSON into the input panel.
  2. Choose Pretty Print or Minify.
  3. Review validation errors if any are shown.
  4. Copy or download the cleaned output.

Best uses

  • Clean up API responses before sharing.
  • Reduce payload size for embeds or quick checks.

Common issues

  • Single quotes are not valid JSON strings.
  • Unescaped line breaks in strings will fail validation.
