Postman Collection → Code Converter
Convert any Postman collection into a full Playwright, Rest Assured, k6, Cypress, Supertest, Python (pytest), or Karate test suite — with folders, pm.test assertions, auth, and environments preserved. Runs 100% in your browser.
import { test, expect } from '@playwright/test';
test.describe("Sample API", () => {
test.describe("Users", () => {
test("List users", async ({ request }) => {
const response = await request.get(`${process.env.BASEURL ?? ""}/v1/users?active=true?active=true`, {
headers: {
"Accept": `application/json`,
"Authorization": `Bearer ${process.env.AUTHTOKEN ?? ""}`
}
});
expect(response.ok()).toBeTruthy();
expect(response.status()).toBe(200);
// Assert response time < 500ms (measure with performance.now())
});
test("Create user", async ({ request }) => {
const response = await request.post(`${process.env.BASEURL ?? ""}/v1/users`, {
headers: {
"Content-Type": `application/json`,
"Authorization": `Bearer ${process.env.AUTHTOKEN ?? ""}`
},
data: {
"name": "Alice",
"email": "alice@example.com",
"role": "admin"
}
});
expect(response.ok()).toBeTruthy();
const json = await response.json();
expect(response.status()).toBe(201);
expect(json.email).toBe("alice@example.com");
});
});
});Why this beats Postman's built-in code snippet and every online converter
Whole-collection conversion
Postman's snippet handles one request at a time. This tool converts hundreds of requests, preserves nested folder structure, and turns them into runnable describe/scenario blocks.
Real test-framework output
Playwright test blocks, Rest Assured @Test methods, k6 groups + thresholds, Cypress it() blocks — not just an HTTP client call.
Local-only, secret-safe
Every parser and generator runs in your browser. Your collections and environment files never leave the page — safe for internal APIs.
pm.test → assertions
Translates pm.response.to.have.status(), pm.expect(json.x).to.eql(), response time, headers, and body checks into idiomatic per-framework asserts.
Handles every body type
raw JSON, urlencoded, formdata, GraphQL, and file uploads — mapped to Playwright's data/form, Rest Assured .body(), k6 JSON.stringify, and more.
Environment file support
Upload a Postman environment.json — values inline into code, or emit process.env / __ENV / Cypress.env references you can override in CI.
How to convert a Postman collection in 4 steps
Export your Postman collection
In Postman, right-click the collection → Export → Collection v2.1 (recommended). Optionally export an environment as well (Environments → Export).
Upload or paste the JSON
Drop the .postman_collection.json file into the left panel (or paste the JSON). The tool auto-detects v2.0/v2.1, folders, auth, variables, and pm.test scripts.
Pick a target framework
Choose Playwright, Rest Assured, k6, Cypress, Supertest, Python (pytest), Karate, or a cleaned Postman collection. The output updates instantly with folder structure preserved.
Copy, download, or download the full suite
Copy one file, download the current file, or download the full suite as a ZIP with per-folder files plus a runnable config (playwright.config.ts / pom.xml / cypress.config.js).
