What Does This Markdown Formatter Clean Up?
This tool normalizes common Markdown inconsistencies rather than rewriting your content: it adds a space after heading # marks where missing, converts * and + bullet markers to a consistent -, strips trailing whitespace from every line, collapses three or more blank lines down to one, and ensures the file ends with exactly one newline. Code block contents are left untouched.
