Is output sanitized for XSS attacks?

Sanitization depends on parser implementation. Review output before publishing; always sanitize user-generated Markdown input.

Does it support every Markdown extension?

Core CommonMark syntax is supported. GFM (GitHub Flavor), Markdown Extra, and other extensions may vary by implementation.

Most parsers allow raw HTML passthrough. Behavior varies; some sanitize or escape HTML. Check your parser's docs.

Single newlines are collapsed into spaces. Double newlines create paragraph breaks. Use trailing spaces or for line breaks within paragraphs.

Yes. [text][ref] with [ref]: url on a separate line. Many parsers support this pattern for cleaner source.

Tables are a GFM extension, not core Markdown. Support depends on the parser used by your tool.

Data Workshop Tools

Convert Markdown syntax into sanitized HTML output locally.

<h1>ScriptPulse</h1></p><p><ul><li>fast</li></ul><ul><li>private</li></ul>

Markdown to HTML converts Markdown-formatted text into clean HTML for documentation, blogs, and static sites.
Transform README files, release notes, and content into renderable, web-ready HTML.

Paste Markdown-formatted text into the editor.
The converter parses Markdown syntax and generates corresponding HTML structure.
Review the generated HTML output.
Copy output for use in docs, blogs, CMS systems, or static site generators.

Results should be validated in your target runtime before production use.
Extremely large input payloads may be constrained by browser memory and performance limits.

Missing space after # in headers: #Header (invalid), # Header (valid)
Incorrect link syntax: [text] (url) or [text](url) without parentheses fail
Unescaped special chars: *, _, [, ] in text may trigger formatting. Escape with backslash: \*
Mixing ordered/unordered: Switching between 1. and - resets nesting. Keep lists consistent.
Indentation for code blocks: Triple backticks require proper code block delimiters. Indentation alone does not create code blocks in all parsers.
HTML injection: Raw HTML in Markdown may not be sanitized. Review output before publishing user-generated content.

How are line breaks handled?
Single newlines are collapsed into spaces. Double newlines create paragraph breaks. Use trailing spaces or <br /> for line breaks within paragraphs.
