JSON to OpenAPI Schema
Generate an OpenAPI 3.0 schema from a JSON sample in YAML or JSON format.
About JSON to OpenAPI Schema
Convert a JSON sample object into a complete OpenAPI 3.0 schema definition. The tool automatically infers types — strings, integers, floats, booleans, arrays, and nested objects — and generates a schema you can copy directly into your API documentation. Output in either YAML or JSON format.
Private & free — this tool runs entirely in your browser.
