Markdown Formatter
Format and indent Markdown code into a clean, readable structure directly in your browser.
This tool runs entirely in your browser. Your files are never uploaded to a server.
# Title
* item one
* item twoWhat this formatter does
Splits Markdown-like text into lines, then on each line ensures a space after 1-6 leading # characters for ATX headings, normalizes -, *, or + list markers to exactly one following space, and removes trailing whitespace. Runs of three or more blank lines collapse to a single blank line.
How to use it
Paste Markdown into the editor and the formatted result updates immediately. Copy the result when ready, or use Reset to clear the editor; Reset does not restore the original sample.
Formatting behavior
#Title becomes # Title automatically for headings 1 through 6, and bullet markers like -item become - item. Three or more consecutive blank lines are reduced to one, and the whole document is trimmed of leading and trailing blank lines.
Important limitations
This is a line-based text cleaner, not a CommonMark parser, linter, or table/link-reference formatter — it does not reflow paragraphs, align tables, renumber ordered lists, or touch fenced code blocks. Two side effects matter: trailing-whitespace removal deletes Markdown's "two trailing spaces equal a line break" hard-break syntax, and the list-marker cleanup strips all leading whitespace from a line, removing the indentation that distinguishes a nested list item from a top-level one.
Safe review workflow
Because nested-list indentation and trailing hard breaks are removed, review the output before publishing content that relies on either, and re-indent nested lists manually if needed. Keep the original source available for comparison.
