작동 방식

Paste a JSON API response into the text area, set endpoint path and HTTP method. The tool infers OpenAPI 3.0.3 schema from example data for Swagger or Redoc documentation. Use a representative success payload with all fields populated for best schema coverage. Financial API responses with nested quote objects, arrays of holdings, and optional fields should appear in the sample if you want them documented for downstream consumers. Empty arrays in samples produce generic array schemas without item structure until you include at least one element. Pretty printed JSON and minified JSON both parse correctly. Financial API responses with nested quote objects and holdings arrays should show all fields in sample JSON for complete schema. Include error response samples in separate paste when documenting production API surface area completely. Include nullable fields in sample JSON when API returns null for optional finance quote keys.

Include error response samples in separate paste when documenting production API surface area completely. Include nullable fields in sample JSON when API returns null for optional finance quote keys.

Review generated info block, paths section, response schema, and components with schema references. Copy YAML into Swagger Editor or your API repository docs folder. When fields are optional in production, include them in the sample JSON or add nullable flags manually after export. Run openapi linter validation in CI so schema drift is caught when backend responses change shape between releases without updating docs. Download button saves YAML for direct commit into your docs repository. Run openapi linter in CI after export: backend response drift breaks clients when optional fields disappear silently. Components section deduplicates nested objects shared across multiple endpoints in large APIs. Paste nested quote response from Yahoo proxy or broker API to document finance chart endpoints.

공식

Type inference: typeof checks with integer detection. Schema builder recursively walks JSON object keys. YAML emitter formats OpenAPI 3.0.3 structure: info, paths, components with $ref.

Output is OpenAPI 3.0.3 YAML string. Paste into Swagger Editor or API docs tools. Validate generated spec with an openapi linter before publishing to production documentation. Request body schemas, security schemes, and webhook callbacks require manual authoring after export completes. Nullable inference requires null in sample JSON: absent keys are treated as required in output schema. Example driven schema marks all sampled fields required: add nullable true manually for optional API fields. OpenAPI version 3.0.3 chosen for broad tooling support across Swagger Redoc and gateway validators. Validate output YAML with openapi linter in CI before publishing to production docs.

Convert portfolio configs with YAML to JSON Converter when documenting internal tooling alongside external API specs on portfolios. Use those calculators when json to openapi converter alone does not capture the full decision.

FAQ

How is the JSON schema inferred?

The tool parses JSON objects or arrays, infers types for each field, and generates OpenAPI 3.0.3 YAML with path, method, response schema, and component references. Type inference walks each key and builds required arrays for nested objects automatically from sample structure. Arrays of primitives become items with type only while arrays of objects generate full item schemas. Union types and oneOf branches are not inferred automatically when sample shows only one variant. Nested null values in samples may infer nullable types depending on parser behavior. OpenAPI 3.0.3 output imports into Swagger UI Postman and Redoc without modification. Type inference walks nested objects and builds components schemas referenced from paths section. OpenAPI 3.0.3 output imports into Swagger UI Postman and Redoc without modification. Type inference walks nested objects and builds components schemas referenced from paths section.

What types are detected?

Integer if value is a whole number. Floating prices parse as number type. Object fields become nested schemas with properties and required arrays. Arrays whose first element is an object recurse into item schemas. Nullable fields missing from sample JSON will not appear until you add examples. String enums are not inferred automatically: document allowed values manually after export if your API uses fixed vocabularies like order status codes. Array of objects generates item schema with required fields inferred from first element shape. Array of objects generates item schema with required fields inferred from first element shape.

How do I use the generated YAML?

Paste API response JSON, enter endpoint path and HTTP method. Generated YAML imports into Swagger UI, Redoc, or Postman for interactive docs. Add request bodies, authentication, and error responses manually after import because this tool documents response shape from examples only. Version the generated YAML in git beside your API repo for diff review on each release when response fields change. Client SDK generators like openapi generator consume the exported YAML to produce typed language bindings. Authentication and error responses are manual post steps: this tool documents success body shape from one example only. Required array in schema lists every key present in sample: add null samples for optional API fields. Authentication and error responses are manual post steps: this tool documents success body shape from one example only. Required array in schema lists every key present in sample: add null samples for optional API fields.

What OpenAPI sections are generated?

YAML structures info, paths, and components sections. Schema references use ref notation to components schemas. Large nested responses stay readable because shared objects live once under components instead of being duplicated per path. Portfolio API responses with nested quote objects and holdings arrays benefit from component reuse when the same position object appears in multiple endpoints. HTTP method and path fields map to paths object keys in generated YAML structure. HTTP method and path fields map to paths object keys in generated YAML structure.

Does the tool generate request schemas?

This is example driven schema generation, not full API design. Production APIs need manual addition of pagination, error codes, and auth schemes beyond what a single success response shows. Maintain separate example files for error payloads if clients must handle validation failures and server errors explicitly. Contract first teams often paste production success and error samples sequentially to build complete specs. Webhook callback schemas require separate JSON samples because this tool processes one response body at a time. Version schema in git beside API handlers so frontend types and OpenAPI stay synchronized each release. Pagination query params must be added manually after example driven generation completes. Import generated YAML into Postman collection for team shared API documentation without manual retyping.
