About JSON Schema Validator
Check data structure and constraints with a useful client-side JSON Schema subset.
The supported scope is stated clearly because the project does not include a full standards validator.
Input is processed locally in your browser and is not sent to Navorika.
How the calculation works
Supported structural rules
type, properties, required, additionalProperties, items, minItems and maxItems are supported.
Supported value rules
minimum, maximum, minLength, maxLength, pattern, enum, const, anyOf, allOf and oneOf are supported.
How to use this tool
- 1Enter JSON data.
- 2Enter a JSON Schema object.
- 3Fix syntax errors if shown.
- 4Review each validation issue and its path.
Understanding the result
A valid result means no violation was found within the documented subset.
Paths begin at $ and identify the affected property or array index.
Important limitations
- This is not a full JSON Schema implementation and does not process references, formats, conditionals or draft-specific vocabularies.
- Regular-expression patterns use JavaScript RegExp behavior.
