How It Works

The JSON Validator parses JSON text against RFC 8259 specifications:

  • Common JSON Errors: Trailing commas after objects or arrays, unquoted keys, single quotes instead of double quotes, and unescaped control characters.
  • Diagnostics: Detects precise error coordinates (line number and column offset) so syntax bugs can be fixed instantly.
