# 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.

Convert to Markdown

## 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](/content/features/api-docs-automation/index.html).
