Swagger to Postman Converter
Convert OpenAPI 3.x or Swagger 2.0 JSON into a Postman Collection v2.1 locally; your specification is not uploaded.
A QUICK WALKTHROUGH
How to use this tool
- Paste a JSON specification up to 2 MB.
- Convert paths, methods, parameters, headers, and JSON request-body examples.
- Review and download the Postman collection JSON.
Swagger to Postman Converter
Supports JSON documents for OpenAPI 3.x and Swagger 2.0. It creates requests from path operations, combines path-level and operation-level parameters, derives bounded examples from JSON schemas, and adds a baseUrl collection variable. It does not execute requests, validate every specification rule, resolve remote references, or promise lossless conversion of vendor extensions, callbacks, links, multipart payloads, or every security scheme.
Limits
Input is limited to 2 MB and 500 operations. Local $ref traversal and generated examples are depth-limited. Review authentication, server variables, examples, and payloads before using the collection.
