About Postman Collection Viewer
Postman collections are a common way teams share API requests, but you don't always want to fire up the full Postman app just to read one someone handed you. The Postman Collection Viewer imports a collection file and lets you browse its requests, so you can see the endpoints, methods, and structure at a glance in your browser.
Load your collection JSON and the tool lays out its requests in a navigable view, making it easy to understand what an API offers and how each call is shaped. It runs locally in your browser with no signup and no watermark, so a collection that documents private internal endpoints stays on your machine. It's the fast way to review or onboard onto an API that's been documented as a Postman collection.
Common uses
- Review a collection a teammate shared to understand an API before writing any code.
- Browse the available endpoints and methods in a vendor's published Postman collection.
- Inspect how each request is structured when onboarding onto an unfamiliar service.
- Read a private collection of internal endpoints without uploading it to a cloud workspace.
- Quickly check which calls a collection covers without launching the full Postman application.

FAQ
What file format does it accept?
It imports Postman collection files, which are JSON exports of the requests grouped in a collection.
Can I edit the collection here?
The tool is for viewing and browsing requests, not editing. Use it to read and understand a collection's contents.
Is my collection uploaded to a server?
No. The file is parsed in your browser, so collections describing private endpoints stay local to your machine.
Does it run the requests for me?
It displays the requests so you can review them; to execute calls, use one of the API testing tools.
Can I use Postman Collection Viewer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
