About this tool

Converts an OpenAPI 3.x or Swagger 2.0 spec to a Postman Collection v2.1 and back. Covers path/query/header parameters, JSON request bodies, and the base URL (as a {{baseUrl}} collection variable) — nested Postman folders are flattened, and only application/json bodies are carried over (other content types and full JSON Schema validation rules aren't).
