JSON Validator

Validate JSON syntax and get detailed statistics about your JSON data structure

JSON Input

Strict validates against the official JSON specification. Loose tries to auto-correct common JSON-like input (e.g., unquoted keys and trailing commas) before validating.

💡 Tips

  • Paste any JSON data to check if it has valid syntax
  • Get detailed error messages with line and column numbers
  • View comprehensive statistics about your JSON structure
  • Perfect for debugging API responses or configuration files
  • Supports nested objects and arrays of any depth
