About OpenAPI Parser
The OpenAPI Parser turns an OpenAPI/Swagger spec (JSON/YAML) into a structured endpoint list with each method, path, and summary. Useful as a first step to generate docs, clients, or tests from a spec.
Native parsing; in the browser.
FAQ
Are any network requests sent?
No. This tool only transforms/analyzes text in your browser — no actual HTTP request is sent, and your data never leaves your device. (Tools that truly call an external server are intentionally not provided due to browser CORS limits.)
Is my data safe?
Yes. All processing happens entirely locally in your browser. Nothing is uploaded, logged, or stored on our servers.
