About MarkdownTidy
What this is
Three Markdown tools that run in your browser. Nothing you paste is uploaded.
| Tool | What it changes | What it leaves alone |
|---|---|---|
| Tidy (home page) | Trailing whitespace on every line; blank lines at the start and end. | Everything else. It also deletes the two trailing spaces Markdown reads as a hard line break. |
| Table formatter | Padding inside GFM pipe tables, and the separator row. | Prose, code fences (including tables inside them), and tables with a row wider than the header. |
| Linter | Nothing; it only reports. | Not a parser: it ignores fenced code and does not understand indented code blocks or HTML blocks. |
When to use something else
prettier --parser markdown reformats a whole document, including lists and emphasis markers, and markdownlint enforces a style in CI. This site is for the quick fix on a pasted snippet.
