Validation result
JSON is valid for this schema.
How to validate JSON with a schema
Paste JSON and a JSON Schema to check common structure rules such as required fields, types, enums, lengths, ranges, array items, and additional properties.
Rules this validator checks
The validator supports common type checks, required object keys, properties, additionalProperties false, enum, const, string length, string pattern, numeric minimum and maximum, array length, and item schemas.
Unsupported schema keywords
Some JSON Schema features are detected but not evaluated, including oneOf, anyOf, allOf, not, $ref, if/then/else, dependencies, patternProperties, and format. When those appear, the tool shows a warning.
Reading errors
- Each issue includes a JSON path such as $.id or $[1].name.
- Fix syntax errors before checking schema rules.
- Treat a warning about unsupported keywords as a reason to use a full validator before production.
Validation notes
Schema validation is only as complete as the rules this tool evaluates. Use a full JSON Schema validator when unsupported keywords are central to your contract.
Preguntas frecuentes
Does it support $ref?
No. $ref is detected as unsupported and is not resolved, so schemas that rely on references need a full JSON Schema validator.
Does format validate emails or URLs?
No. The format keyword is reported as unsupported. Use pattern or a full validator if format checks matter.
Can it validate tuple arrays?
Yes. When items is an array of schemas, each array position is checked against its matching schema.
Why does valid JSON still show issues?
Valid JSON syntax only means the text parses. Schema validation then checks whether the parsed value follows the schema rules.
