Drop or paste a Postman collection (v2.1 JSON) and explore folders, requests, headers, and bodies in a clean tree.
This postman collection viewer runs 100% in your browser. Nothing you paste, drop, or generate ever leaves your device - no analytics on your input, no uploads, no logs.
Use Postman to upgrade to v2.1 - older format isn't supported.
Same browser-only philosophy. Free, no signup, no upload.
Send GET/POST/PUT/PATCH/DELETE requests with headers and JSON body.
Generate a curl command from URL, method, headers, and JSON body.
Beautify, validate, and minify JSON with sortable keys, exact error positions, and a one-click copy.
Validate JSON syntax with exact line and column for every error.
Strip whitespace from JSON to produce a single compact line.
Convert a JSON array of objects into a downloadable CSV file.
We design and ship internal tooling, dashboards, and customer-facing utilities. Tell us what you need and we'll scope it.
