What is JSON to JSON Schema?

Generated schemas follow JSON Schema Draft-07 specifications, including $schema declarations, type definitions, property descriptions, and required field lists. The tool intelligently analyzes JSON data structure, generating corresponding sub-schemas for nested objects and arrays, automatically inferring each field type (string, number, boolean, array, object, etc.).
