JSON Schema Generator
Infer a JSON Schema from a sample JSON document, with draft selection and required policies.
為什麼用這個工具
03Paste a JSON sample and get a draft-2020-12 or draft-07 schema with detected string formats, merged array items, and configurable required handling.
JSON Schema Generator infers a schema from a sample JSON document so you can validate future payloads, generate TypeScript, or document APIs.
It merges array element schemas, detects common string formats (date-time, email, uri, uuid), and supports draft 2020-12 and draft-07.

常見問題
03
What does the smart required policy do?
For arrays, every element schema is merged and only the keys present in every element stay required. For single objects it behaves like 'all required'.
Does it detect string formats?
Yes. Date, date-time, email, uri, and uuid formats are inferred from sample values.
Is my JSON sent anywhere?
No. Inference runs entirely in this tab.
