JSON Schema Generator

What this does

• Walks the sample JSON recursively and emits a Draft-07 schema
• Picks the right type for each leaf: string / integer / number / boolean / null
• For arrays, infers the items schema by sampling all elements (uses oneOf if heterogeneous)
• For objects, generates properties and (optionally) required from observed keys
• Detects common string formats (email, uri, date, date-time, uuid, ipv4)

Workflow

• Paste a representative API response or config sample
• Tweak required and additionalProperties based on your contract
• Copy into your repo as a schema file or paste into an OpenAPI components.schemas block
• Use with ajv, jsonschema (Python), gojsonschema or any validator
