Swagger to JSON

About This Tool

Converts Swagger YAML (OpenAPI 2/3) specs to JSON, enabling downstream tooling and documentation workflows. Target users: API developers, integrators, and QA teams who automate API documentation and client generation.
The tool parses YAML, maps paths, components, parameters, and responses to a JSON object, and can optionally resolve internal $ref pointers to a single, dereferenced output. It preserves the structural semantics of the OpenAPI document while producing a compact JSON representation suitable for programmatic consumption.
Core capabilities include YAML parsing, OpenAPI version awareness, and optional dereferencing. Optional features support internal reference resolution, schema extraction, and pretty vs minified output. It does not fetch remote references unless provided in the input bundle. Validation against the OpenAPI schema is recommended as a separate step.
Benefits include faster integration of API specs into build pipelines, reliable client SDK generation, and consistent documentation sources. Use cases span API gateways, SDK generators, automated tests, and documentation pipelines. The tool differentiates itself by robust handling of common YAML constructs, accurate OpenAPI mapping, and clear error signals for invalid or partially migrated specs.
