Why is my Markdown table not rendering correctly?

Markdown tables require: (1) A header row with columns separated by pipe characters |. (2) A separator row immediately below the header with at least three dashes per column: |---|---|---|. (3) Data rows in the same pipe-separated format. The separator row is mandatory — without it, the parser does not recognise the table syntax. Also ensure there are no blank lines between the header, separator, and data rows.

Can I convert a whole .md file, not just pasted text?

The tool works with pasted Markdown text. To use a .md file, open it in any text editor (Notepad, VS Code), select all content (Ctrl+A), copy, and paste into the editor panel here. This works for any size of Markdown document.

Does this support Markdown front matter (YAML metadata at the top of .md files)?

YAML front matter blocks (--- delimited sections at the start of Markdown files used by static site generators like Jekyll, Hugo, and Astro) are not part of the Markdown specification and are not parsed by marked.js by default. If you paste a file with front matter, the --- delimiters and YAML content may appear as paragraph text in the output. Strip the front matter before pasting if you only need the content HTML.

How do I add a line break within a paragraph in Markdown?

In Markdown, a single line break in the source does not create a in the output — the parser treats it as continued text in the same paragraph. To create a hard line break within a paragraph, end the line with two or more spaces before pressing Enter. Alternatively, use explicit HTML tags, which pass through the parser unchanged.

Markdown to HTML Converter

Markdown is the default writing format for technical documentation, README files, blog posts in static site generators, wiki entries, and developer notes. But the moment you need to paste that content somewhere that expects HTML — a CMS, an email template, a landing page, a documentation platform — you need a reliable Markdown-to-HTML converter that handles all the edge cases correctly: fenced code blocks with syntax hints, tables, strikethrough text, task lists, footnotes, and nested blockquotes. The Utility Spark Markdown to HTML Converter uses the marked.js library — the same parser used by GitHub, VS Code extensions, and thousands of documentation tools — to produce clean, spec-compliant HTML output from your Markdown source. Type or paste on the left side; the rendered HTML preview appears on the right in real time. Switch to the HTML source view to copy the raw tags for pasting into your target system. Everything runs in your browser. Your content — which might be draft documentation, a client article, or proprietary technical writing — never leaves your device.

Why use our tool?

GitHub Flavored Markdown (GFM) Support

Standard Markdown covers headings, bold, italic, links, and lists. GitHub Flavored Markdown extends this with tables, fenced code blocks (```language), strikethrough (~~text~~), task lists (- [ ]), and auto-linking URLs. This tool's parser supports GFM syntax, which covers the vast majority of real-world Markdown content in use.

Live Side-by-Side Preview

As you type or edit in the Markdown panel, the rendered HTML preview on the right updates in real time with sub-100ms latency. You can see exactly how your formatted text, tables, and code blocks will look without switching tabs or clicking a button. The preview uses sensible default styles to make the output visually readable.

Raw HTML Source Copy

Toggle between the visual preview and the raw HTML source view to copy the actual tags. The HTML output is clean and semantic — proper heading tags (h1-h6), paragraphs, ordered and unordered lists, code and pre blocks, blockquotes, and table markup. No inline styles, no framework-specific classes, no proprietary attributes.

Your Content Processed Locally

The marked.js parser runs as a JavaScript library inside your browser. Draft documentation, confidential technical writing, proprietary system descriptions, and client-facing content are processed in your local browser context — never transmitted to an external server for parsing.

Code Block Syntax Highlighting

Fenced code blocks with language hints (```python, ```javascript, ```sql) are rendered with language-appropriate syntax classes in the HTML output, compatible with popular syntax highlighting libraries like highlight.js and Prism.js. Copy the HTML and drop it into any page that already loads one of these libraries.

How it works

1

Type or paste your Markdown content into the left editor panel.

2

The right panel updates in real time with the rendered HTML preview — check that all formatting renders as expected.

3

For tables, ensure your pipe-delimited syntax is correct: each column separated by | with a header separator row using --- dashes.

4

Click 'View HTML' to switch to the raw HTML source view.

5

Click 'Copy HTML' to copy the complete HTML output to your clipboard, ready to paste into your CMS or template.

Frequently Asked Questions

Does this tool support GitHub Flavored Markdown (GFM)? expand_more

Yes. The marked.js parser supports GFM syntax including tables (pipe-delimited), fenced code blocks with language hints (```language), strikethrough using ~~double tildes~~, task list checkboxes (- [ ] unchecked and - [x] checked), and automatic URL linking. This covers the full GFM specification used by GitHub READMEs, GitHub Wiki, and most technical documentation platforms.

Is my Markdown content sent to a server for parsing? expand_more

No. The marked.js library runs entirely within your browser's JavaScript engine. Parsing happens locally — your Markdown text is processed in memory and the HTML output is generated without any network request. Draft documentation, confidential technical writing, or client-facing content is never transmitted externally.

Can I use the HTML output directly in my CMS? expand_more

Yes, with one caveat: the output is clean semantic HTML without any CSS styling. The visual appearance in your CMS will depend on that CMS's own stylesheet rather than the preview shown in this tool. If your CMS's styles conflict with the generated HTML structure, you may need to adjust the markup. The HTML is compatible with all standard CMSs including WordPress, Webflow, Contentful, and static site generators.

Does the converter support HTML mixed with Markdown? expand_more

Yes. Standard Markdown parsers, including marked.js, allow raw HTML to be embedded within Markdown content. HTML tags like
