Free browser-based converter

Convert OpenAPI to clean Markdown.

Paste or upload an OpenAPI or Swagger JSON/YAML file. Get a portable Markdown reference with authentication, endpoints, parameters, responses, and schemas. Nothing is uploaded.

OpenAPI input

JSON or YAML

Markdown output

Ready for conversion

Your Markdown reference will appear here.

Use a production spec to expose the gaps a small example will hide: operation names, auth overrides, schemas, and responses.

What it converts

The contract layer, without pretending it is the whole docs set.

OpenAPI 3.x JSON and YAML

Swagger 2.0 JSON and YAML

Servers and authentication schemes

Endpoint parameters and request bodies

Response codes and schemas

Reusable component schemas

Your spec stays local

Parsing and conversion happen in your browser. The tool does not send the document to a DocsAlot API.

What Markdown cannot infer

A contract does not know your recommended workflow, account setup, migration sequence, or support policy. Add those as authored guides.

Build the complete system

Connect references to SDKs, CLIs, onboarding, and change detection with API documentation automation.
