smartypants for Mac

smartypants is a small command-line tool for typographically beautifying plain text. It mainly handles details that are easily overlooked in writing, such as converting straight quotes into curly quotes that better match publishing conventions, turning consecutive hyphens into em dashes, and handling ellipses. If you often write in Markdown or other plain-text formats and want the final text to look more refined and closer to formal typesetting, it comes in handy. It suits writers, bloggers, or anyone who cares about how text looks. It is simple to use: run it once in the terminal to complete the conversion, with no complex configuration required.
