Instantly validate JSON syntax with detailed error messages and line numbers. View structure stats, beautify, or minify valid JSON.
The PixelForge JSON Validator checks whether your JSON is syntactically valid and pinpoints any errors with line and column references. Invalid JSON is a very common source of bugs in web development — a missing comma, trailing comma, or unquoted key can cause silent failures in APIs and configuration files. Paste your JSON and the validator reports exactly what is wrong and where, or confirms the JSON is valid.
