What to expect
- Generates accessible markup with a proper `<thead>` and `<tbody>`.
- A list of mappings becomes one column per key, one row per item.
- Values are HTML-escaped automatically to prevent broken markup.

YAML to HTML Table Converter FAQ
Does this convert Swagger or OpenAPI YAML into API documentation?
No — this tool converts any YAML into a generic HTML table, not into interactive Swagger/OpenAPI documentation. If you're looking to render an OpenAPI spec as browsable API docs, dedicated tools like Swagger UI or Redoc are built specifically for that.
Can I convert YAML to HTML in Python?
Yes — load the YAML with PyYAML, then build the table with a templating library like Jinja2, or construct it directly from the parsed data. This tool produces the same table markup instantly for a quick one-off conversion.
Is the generated table accessible?
Yes, it uses semantic `<table>`, `<thead>`, and `<tbody>` elements that assistive technology can navigate.
Can I style the table afterward?
Yes, the markup is unstyled by design so it inherits your site's CSS or you can add classes yourself.
Is there a difference between .yml and .yaml?
No. ".yml" and ".yaml" are just two file extensions for the exact same format — this converter accepts either one, so a "yml to HTML" conversion and a "yaml to HTML" conversion produce identical results.
