What problem does this tool solve?
Markdown makes structured text easy to write, but a syntax mistake can produce unexpected formatting. This formatter helps you clean a Markdown document, review supported elements, and export readable HTML.
Six practical questions answered
How can I review Markdown before publishing it?
Paste the document and process it. The preview displays supported headings, lists, tables, links, and code blocks so you can check the structure.
How do I write headings in Markdown?
Use one # for a top-level heading and additional # characters for lower levels. Put a space between the markers and the heading text.
How do I format a Markdown list?
Start unordered items with a hyphen and a space. For an ordered list, use a number followed by a period and a space. Check nested items in the preview.
How do I create a table in Markdown?
Separate cells with vertical bars and include a delimiter row below the headings. This tool supports GitHub-style tables and shows them in the preview.
How can I convert Markdown to HTML?
Process the document and use the HTML output below the preview. Copy the generated code or download an HTML file. Only supported Markdown elements are rendered; raw HTML remains escaped text.
How do I avoid unexpected Markdown rendering?
Review headings, lists, links, and code fences in the preview. Different publishing systems may use other extensions or styles, so also inspect the document in its final destination.
Practical example
A developer writes a README with headings, a table, and code samples. They review the preview, fix a misplaced code fence, and save the Markdown source or HTML output as needed.
How to use the tool
Paste Markdown, process it, and review the preview. Download the cleaned .md source, or copy and save the HTML output below the preview.
Additional use cases

Limits and supported formats
Limit: 100,000 characters; preview and HTML export up to 5,000 elements and 30 nesting levels. Embedded HTML stays text and external images are not loaded. Platform-specific extensions may differ.
