## How it works

- Paste a Markdown pipe table into the Markdown Input field.
- Choose CSV, JSON, or JSON Schema as the output format.
- Set the CSV delimiter, header option, null tokens, and required-field mode when needed.
- Run the conversion to receive text output with type and alignment diagnostics.
