Frequently Asked Questions

What JSON Schema draft versions are supported?
The tool supports JSON Schema drafts 04, 06, 07, 2019-09, and 2020-12. Each draft has different features and keywords, with newer drafts providing more validation capabilities.
How does schema generation work?
The tool analyzes your JSON data structure and automatically infers appropriate schema rules including data types, formats (email, URI, date), required fields, and nested object structures.
What types of validation errors are detected?
Detects type mismatches, missing required properties, constraint violations (min/max, length), format validation, pattern matching, enum validation, and structural errors.
Can I validate complex nested structures?
Yes, the tool handles deeply nested objects, arrays with complex items, conditional schemas, and recursive structures with proper error path reporting.
How do I handle validation warnings vs errors?
Errors indicate schema violations that make data invalid. Warnings suggest potential issues like unexpected properties or suboptimal schema design, but don't invalidate the data.
