JSON Schema Generator
This enhanced JSON Schema Generator:
- Accepts a single object or array of objects to infer optional vs. required fields.
- Lets you select between Draft‑04, Draft‑07, or 2019‑09 schema versions.
- Provides toggles for
additionalPropertiesand includingrequiredarrays. - Shows the generated schema inline with one‑click copy.

{ "name": "Alice", "active": true },

}Why These Features Matter
- Accurate models: auto‑detect which fields must exist and which are optional.
- Version alignment: generate schemas that match the JSON‑Schema draft your project uses.
- Strictness control: choose whether extra fields are allowed or disallowed.
- Build docs & tests: drop this schema into OpenAPI specs or validator suites.
When to Use
– Create validation rules for API requests/responses.
– Enforce config file structure in CI/CD pipelines.
– Document data models in team‑shared repositories.
