Markdown formatters

Tidy, restructure and analyze existing Markdown. Drop a file in, get a cleaned-up file back.

Formatters take a Markdown file you already have and give you a better version of it back — or a short report about it. Pick one from the menu. They fall into three kinds:

Tidy

Reformat and clean up: pretty-print, align tables, sort lists, apply smart typography, escape special characters or strip formatting to plain text.

Structure

Reorganize the document: reference-style links, footnotes, heading numbering, YAML front matter and emoji shortcodes.

Analyze

Understand a document without changing it: lint for style issues, count words and reading time, check links, compare two files or validate against CommonMark.
