OpenAPI to Postman Collection

Paste a spec, download a collection, import it into Postman (Import → File) or run it with Newman — no local Node packages needed. The converter follows Postman's own openapi-to-postman conventions: servers[0] becomes the {{baseUrl}} collection variable (trailing slashes stripped, extra servers kept as baseUrl_2…, server variables like {port} become collection variables), path folders build a collapsed path trie (or use tags), path params become :param segments plus url.variable entries, query/header parameters get “(Required) ” prefixes and enum hints in their descriptions, JSON request bodies are generated with deterministic sample values (example → first enum → default → format-aware values → property-name heuristics like [email protected]), example responses are saved per status code, and bearer/basic/apiKey security schemes become collection auth referencing {{bearerToken}}/{{apiKey}} variables. Swagger 2.0 input is accepted through a compatibility layer. Cookie parameters are dropped with a warning (Postman collections cannot express them).
