What is a JSON Validator?

A JSON validator checks whether your JSON data is correctly formatted according to the JSON specification. It also formats and beautifies JSON to make it readable with proper indentation and line breaks.

Features

  • Validate — Check if your JSON is valid with detailed error messages
  • Format / Beautify — Pretty-print JSON with 2-space indentation
  • Compress — Remove all whitespace for compact JSON
  • Sort Keys — Alphabetically sort all JSON keys
  • Syntax Highlighting — Color-coded display for better readability
  • Secure — All processing happens in your browser

Common Use Cases

Developers use JSON validators to debug API responses, inspect configuration files, and verify JSON data from databases or web services.
