What does the generated Markdown include?

It produces a title and description from the info block, a servers list, and one section per endpoint and method. Each section has the summary and description, a parameters table with name, location, required flag and type, a request body note, and a responses table.

Does it accept YAML and JSON specs?

Yes. JSON is parsed directly and block-style YAML is parsed by a built-in parser covering the indentation and list structures typical of OpenAPI documents. Paste whichever format your spec uses.

How are referenced schemas shown?

When a parameter or body references a component schema with $ref, the tool shows the schema's short name rather than inlining the full definition. Array types are described as an array of their item type.

Can I edit the Markdown afterwards?

Yes. The output is plain Markdown meant as a starting point. Copy it and adjust headings, add examples, or merge it into existing docs. Nothing is locked or proprietary.

Is my spec uploaded to a server?

No. Parsing and generation run entirely in your browser in JavaScript. The spec never leaves your device, so it is safe to document private or internal APIs.

OpenAPI Spec to Markdown Docs

Keeping API documentation in sync with an OpenAPI (Swagger) spec is tedious if you write it by hand. Since the spec already describes every endpoint, parameter, and response, you can template it straight into Markdown. This tool does that in your browser and gives you a clean reference ready to paste into a README or docs site.

How it works

The converter parses your YAML or JSON spec into an object, then templates it section by section:

The info block becomes the document title and intro; servers become a bulleted list of base URLs.
Each path and HTTP method becomes a ### METHOD /path section, carrying its summary and description.
Parameters — both path-level and operation-level — are merged into a single table with name, location (in), required flag, and type. Request bodies note their media types, and responses become a code/description table.

Markdown special characters in descriptions are escaped so pipes and newlines do not break the generated tables.

Example

An endpoint defined as GET /pets with a limit query parameter renders as:

### `GET /pets`

**List pets**

**Parameters**

| Name | In | Required | Type | Description |
|------|----|----------|------|-------------|
| `limit` | query | no | integer | |

A $ref to a component schema appears as the schema’s short name in backticks rather than its full path.

Notes

The output is a faithful starting point, not a substitute for hand-written prose where it matters — add request/response examples and prose explanations after generating. Everything is produced locally, so your spec and the resulting docs never leave your device.
