What is JSON to JSON Schema?
JSON Schema is the standard way to describe and validate JSON. This tool walks your sample and infers type, properties, and required for every level. Strings that look like emails, URLs, or ISO dates get the matching format hint automatically. Choose draft 2020-12, 2019-09, or draft-07 for your $schema URL.
