Why use a Markdown formatter?

Markdown written by hand accumulates inconsistencies quickly: ATX vs Setext headings, ordered lists that restart numbering, code blocks that mix fenced and indented styles, and link syntax that alternates between reference and inline forms. QuickKit's Markdown formatter uses Prettier's Markdown plugin to normalize all of these, producing clean, consistent Markdown that renders identically across GitHub, GitLab, Notion, and any Markdown parser. It also formats embedded code blocks using language-specific formatters — a JSON block inside your Markdown gets formatted as JSON.
