Keep the CSV quoting intact

The first row becomes the header. Short rows receive empty cells. Quoted line breaks become visible separators inside one Markdown cell.

Name,Note
Alex,"Review, then share"

When the CSV cannot be parsed

Close each quoted field and use a doubled quote for a literal quote inside it. This tool supports comma-separated CSV, not every spreadsheet dialect.
