Validador de JSON Schema
Valida datos JSON contra un JSON Schema con Ajv, enumerando cada infracción con su ruta. Funciona por completo en tu navegador.
Cómo usar
Put a JSON Schema in the first editor and the JSON data to check in the second, then press Validate. Validation uses Ajv with all-errors reporting: every mismatch is listed with its path (for example /age) and message. The Person and Product example buttons load ready-made pairs — try changing the data values to see errors appear. If the schema itself is invalid against the draft meta-schema, that is reported too.
Notas
Everything runs locally; neither the schema nor the data leaves your browser. Note that format assertions such as format: "email" are treated as annotations by Ajv's default build (ajv-formats is not bundled), so they are not enforced — use pattern if you need to check a format here.
Preguntas frecuentes
Which JSON Schema draft is supported?
Ajv's default, draft-07. Schemas declaring draft 2019-09 or later may behave differently.
Why do I only see one error?
All-errors reporting is enabled, so validation errors are all listed. The exception is a schema that fails to compile — that stops the process earlier.
