Format and Fix Markdown Online — No Signup Required

Common issues this fixes

  • Markdown exported from tools has inconsistent formatting and broken tables
  • Copy-pasted content from the web contains HTML residue and invisible characters
  • AI-generated Markdown has structural issues that don't show until you paste it somewhere
  • Existing Markdown formatters only prettify — they don't fix structural problems

How it works

  1. 1Paste your messy Markdown into the editor (plain text, HTML, or mixed)
  2. 2Click "Fix Formatting" — structural issues are repaired, formatting is normalized
  3. 3Copy the clean output as Markdown (.md) or rich text for Notion

Frequently asked questions

Is this a Markdown prettifier or a formatter?
Both. It normalizes spacing and formatting like a prettifier, but it also repairs structural problems — broken tables, skipped heading levels, collapsed list indentation, missing code block tags. Think of it as a formatter that actually fixes things.
Does it work with GFM tables and task lists?
Yes. GitHub Flavored Markdown extensions including tables, task lists (checkboxes), and strikethrough are fully supported and properly formatted.
Can I use it for content going to Obsidian, Logseq, or other tools?
Yes. The output is standard, well-structured Markdown that works in any Markdown editor or note-taking tool — Notion, Obsidian, Logseq, Typora, VS Code, and more.
