JSON Schema Generator

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 additionalProperties and including required arrays.
  • Shows the generated schema inline with one‑click copy.
Core Example

Input:

[ { "name": "Alice", "active": true }, { "name": "Bob", "age": 30 } ]

Settings:

Draft: draft‑07  |  additionalProperties: false  |  include required: true
Generated Schema:

Output:

{ "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "name": { "type": "string" }, "active":{ "type": "boolean" }, "age": { "type": "integer" } }, "required": ["name"], "additionalProperties": false }
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.
