Syntax & Structural Verification Process

The validation engine performs lexical analysis against the formal grammar, schema definitions, or RFC requirements of the format. It verifies bracket matching, character encoding integrity, required attribute existence, and delimiter consistency. If an anomaly is found, the validator pinpoints the exact line and column location alongside an actionable explanation of the syntax violation.

Preguntas frecuentes

Which JSON Schema draft do I use?
Libraries and OpenAPI versions differ. Align the draft with your runtime (Ajv, .NET, Java) and pin it in repos so validation stays stable.
Schema validator vs plain JSON validator?
Syntax validation ensures JSON parses. Schema validation ensures the parsed object matches business rules—both steps matter in production.
