05Swagger / OpenAPI → Postman collection
Turn any Swagger or Redoc page into a Postman collection.
One click on a Swagger UI or Redoc page exports a ready-to-import Postman Collection v2.1 — folders by tag, auth baked in, example bodies generated. OpenAPI 3.x and Swagger 2.0, free, and 100% on your device.
No account, no sign-up — detection and conversion run entirely on your device.
(01)Features
Stop hand-scaffolding API tests.
Auto-detects your API spec
Open a Swagger UI or Redoc page and the extension finds its OpenAPI definition automatically — supporting both OpenAPI 3.x and Swagger 2.0, including specs behind a logged-in session.
One-click Postman v2.1 export
Click Convert and a complete Postman Collection v2.1 JSON downloads to your machine — every operation mapped with its URL, path and query params, headers, and request body, ready to import.
Bakes in authentication
Security schemes from the spec are mapped to Postman auth, and you can optionally bake authorization headers straight into the collection — so requests are ready to send, not just ready to configure.
Grouped into folders by tag
Operations are organized into Postman folders by their Swagger tag (or path), so a large API arrives as a tidy, navigable collection instead of a flat dump of requests.
Realistic example bodies
Request and response bodies are scaffolded from the examples and schemas in the spec, using deterministic generation so the same spec always produces the same clean output.
Manual spec URL override
When a page's structure isn't natively parsable, paste an openapi.json or YAML URL directly in the popup and convert that instead — handy for raw spec endpoints and edge-case docs sites.
(02)How it works
Spec to collection in three clicks.
-
1
Open your API docs
Go to any Swagger UI or Redoc page — public or behind your login — then click the Swagger to Postman icon. There is no account and nothing to set up.
-
2
Pick your options
Toggle whether to include auth headers, bake in examples, and group by tag. Or paste a spec URL manually if you prefer. Your preferences are remembered next time.
-
3
Convert and import
Hit Convert. A Postman Collection v2.1 JSON downloads instantly — drag it into Postman (or Insomnia, Hoppscotch, etc.) and start testing.
(03)Privacy
Your API specs never leave your machine.
- Detection and conversion run entirely on your device — your OpenAPI specs and the generated collection never go to a server of ours.
- No analytics, no tracking, no telemetry, and no third-party data collection of any kind.
- The only network request is fetching the spec on the page you are viewing, in your own browser session — the same request the page itself makes.
- Least-privilege by design: it reads the active tab only when you click Convert, and storage holds just your toggle preferences.
(04)FAQ
Questions, answered.
What does Swagger to Postman do?
It detects the OpenAPI specification on a Swagger UI or Redoc page and converts it into a downloadable Postman Collection v2.1 JSON file in one click — so you can import a full, organized set of requests into Postman instead of recreating endpoints by hand.
Which spec versions are supported?
Both OpenAPI 3.x and Swagger 2.0. The extension parses the spec, resolves references, and maps each operation into a Postman request with its URL, params, headers, and body.
Does it work with APIs behind a login?
Yes. It fetches the spec in the page’s own context with your existing session, so specs that require authentication still resolve. You can also bake authorization headers into the exported collection.
How are the requests organized?
Operations are grouped into Postman folders by their Swagger tag (or by path), and example request/response bodies are generated from the spec — so the collection is tidy and ready to send.
What if the page is not detected?
Use the manual override: paste the openapi.json or YAML URL into the popup and convert that directly. It's handy for raw spec endpoints or docs sites with an unusual structure.
Does it send my API specs anywhere?
No. All parsing and conversion happen locally in your browser. There are no analytics and no servers of ours — the only network request is loading the spec on the page you are already viewing.
Can I import the result into tools other than Postman?
Yes. The output is standard Postman Collection v2.1 JSON, which Postman, Insomnia, Hoppscotch, and many other API clients can import.
