Frequently Asked Questions

What is JSON Schema validation?

JSON Schema validation is the process of checking whether a JSON document conforms to a given schema. It verifies data types, required properties, constraints, and structure rules defined in the schema.

How do I validate JSON against a schema?

Provide your JSON data in the input editor and your schema in the settings panel. Validation will happen automatically as you type.

What validation errors might I encounter?

Common validation errors include type mismatches, missing required properties, additional properties not allowed by the schema, string length violations, and number range violations.

Can I use custom JSON schemas?

Yes! You can import or paste any valid JSON Schema (Draft 4, 6, 7, or 2019-09) to validate your JSON data against specific business rules and constraints.
