Markdown FormatterUser Guide

Organize Markdown lists, blank lines, and GFM tables in the browser, compare the differences, and then copy or export the new draft. For special syntax that cannot be confirmed to have consistent semantics, the original manuscript will be retained and a reminder will be given.

How to use

  1. Paste Markdown, or import a UTF-8 .md file.
  2. Press the sorting format, switch between difference and layout preview, and check text, paragraphs and tables.
  3. Copy the cleanup results or export a .md copy.

Formats and limits

  • Maximum 100,000 UTF-16 characters, 3,000 lines; maximum import file size 400 KB.
  • Processes CommonMark and GFM; original HTML, custom syntax, or unverifiable semantics trigger preservation of the original.

Output

Organized Markdown text and new .md copy.

Frequently asked questions

Will the preview execute HTML or load external images?

No. The preview does not execute the original HTML, nor does it load external images; please check the actual exported content based on the differences.

The file name and content are only processed in your browser and are not transmitted to the server. The original file will not be overwritten. Please export the required results before leaving the tool.
