Zendesk Markdown to HTML Converter

Convert Markdown-formatted text into HTML that works correctly in Zendesk Support (triggers, automations, dynamic content, email templates, macros).

Usage

User provides Markdown text, and you convert it to clean, minified HTML.

Conversion Rules

Text Formatting

Markdown	HTML
`bold`	`<strong>bold</strong>`
`italic`	`<em>italic</em>`
`code`	`<code>code</code>`

Headings

Markdown	HTML
`# Heading 1`	`<h1>Heading 1</h1>`
`## Heading 2`	`<h2>Heading 2</h2>`
`### Heading 3`	`<h3>Heading 3</h3>`
`#### Heading 4`	`<h4>Heading 4</h4>`

Lists

Bulleted list:

markdown

* Item one
* Item two

→

html

<ul><li>Item one</li><li>Item two</li></ul>

Numbered list:

markdown

1. Step one
2. Step two

→

html

<ol><li>Step one</li><li>Step two</li></ol>

Nested lists: Use nested <ul> or <ol> inside <li> elements.

Links and Images

Markdown	HTML
`[Link text](https://example.com)`	`<a href="https://example.com">Link text</a>`
`![Alt text](https://example.com/image.png)`	`<img src="https://example.com/image.png" alt="Alt text">`

Block Elements

Code block:

markdown

```
code here
```

→

html

<pre><code>code here</code></pre>

Blockquote:

markdown

> Quoted text

→

html

<blockquote>Quoted text</blockquote>

Horizontal rule:

markdown

Output Requirements

•
Minify the HTML: Write on a single line with no unnecessary whitespace. Zendesk renders extra gaps/spaces in emails if HTML isn't minified.
•
Valid HTML only: Don't include markdown artifacts or partial conversions.
•
Escape special characters: Convert < to <, > to >, & to & in text content (not in HTML tags).
•
No outer wrapper: Don't wrap entire output in <div> or <body> unless specifically requested.

Zendesk Context Notes

•HTML works in: triggers, automations, dynamic content, email templates, CC emails, welcome emails, verification emails
•Markdown works in: agent signatures, macros (with rich content disabled), comment sections
•Dynamic content in triggers/automations may have inconsistent HTML rendering - keep it simple
•Always minify to avoid spacing issues in delivered emails

Workflow

•Parse the user's Markdown input
•Convert each element to its HTML equivalent using the rules above
•Minify the output (single line, no extra whitespace)
•Present the HTML in a code block for easy copying
•Optionally offer a "pretty-printed" version if the user needs to edit it
