About Markdown Formatter
What the formatter cleans up
It applies a small set of safe tidy-ups to Markdown text:
- Ensures one space after the
#characters of a heading, so#Titlebecomes# Title. - Trims spaces just inside bold markers, so
** word **becomes**word**. Spaces outside the markers are left alone. - Collapses three or more consecutive newlines into one blank line.
- Removes trailing spaces and tabs at the end of each line, then trims blank space at the very start and end.
What it does not do
- It does not re-wrap paragraphs, renumber lists, align tables or convert Markdown to HTML.
- Italic markers, links and code fences are not touched.
- A line that really starts with a hash for another reason (a hashtag, for example) will be given a space after it, because the tool cannot tell it from a heading.
- Two trailing spaces used as a hard line break in Markdown are removed, so use a backslash or a blank line instead if you rely on them.
It is a light clean-up for README files and notes, not a full linter. Check the result in a preview before committing.
Frequently Asked Questions
It ensures exactly one space after # heading markers, removes stray spaces just inside ** bold markers, collapses 3+ consecutive blank lines down to one, and trims trailing whitespace from each line.
No — those are left exactly as you typed them; only heading spacing, bold-marker spacing, and blank-line runs are adjusted.
No — the output stays in Markdown syntax; this is a text cleanup tool, not a Markdown renderer or preview.
No — it doesn't validate or fix links, malformed tables, or other structural Markdown errors. Use the Markdown Validator tool for basic structural checks instead.
