UnmarkdownDocs

Destination Details

Detailed guide for each export destination: format specifics, what works, and known limitations.

Google Docs

Google Docs receives HTML with -aw-style-name heading styles, which Google Docs maps to its built-in heading styles. Template colors are applied to headings, text, links, code, tables, and blockquotes. Task list checkboxes use Unicode characters for compatibility.

What Works

  • Headings (H1 through H6) mapped to Google Docs heading styles
  • Bold, italic, strikethrough, highlight, superscript, subscript, and inline code
  • Ordered and unordered lists, including nested lists
  • Task lists with Unicode checkboxes
  • Links with clickable URLs
  • Tables with template colors on headers and alternating rows
  • Code blocks with monospace font and template code background
  • KaTeX math rendered as formatted output
  • Diagrams (Mermaid, Graphviz) rendered as SVG images
  • Callout styling with colored borders and backgrounds
  • Template colors for all text and decorative elements

Limitations

  • Syntax highlighting colors are not preserved in code blocks
  • Chart.js charts are rendered as images, not interactive charts
  • Some complex table layouts may reformat on paste
Tip
Google Docs has the best fidelity of all clipboard destinations. For the most complete export, use Google Docs.

Word

Word output uses HTML with mso-style-name heading styles and Microsoft Office properties. Template colors are applied throughout. Compatible with Word 2016 and later, including Word Online.

What Works

  • Headings mapped to Word's built-in heading styles via MSO properties
  • Bold, italic, strikethrough, highlight, and inline code
  • Ordered and unordered lists with proper indentation
  • Tables with cell borders, header backgrounds, and template colors
  • Links, images (as linked references), and horizontal rules
  • KaTeX math rendered as formatted output
  • Diagrams rendered as SVG images
  • Template fonts and colors applied to all elements

Limitations

  • Syntax highlighting is not preserved in code blocks
  • Word Online has slightly different paste behavior than desktop Word
  • Complex table layouts with many columns may overflow the page width

Slack

Slack uses its own markup format called mrkdwn, which differs from standard Markdown. Unmarkdown translates your content to mrkdwn syntax and copies it as plain text. Paste it directly into a Slack message input field.

Syntax Mapping

  • Bold: *text* (asterisks)
  • Italic: _text_ (underscores)
  • Strikethrough: ~text~ (tildes)
  • Links: <url|label> format
  • Code blocks: Triple backticks (no language identifiers)
  • Headings: Converted to bold text (Slack has no heading support)
  • Tables: No support, converted to formatted text

Limitations

  • No template colors, fonts, or rich formatting
  • Images, diagrams, math, and charts are excluded
  • Nested lists beyond two levels may not indent correctly
  • Long messages may exceed Slack's character limit
Note
Slack mrkdwn is copied as plain text, not rich text. Slack renders the formatting when you paste it into a message field.

OneNote

OneNote receives HTML without MSO properties (OneNote ignores them). Semantic <pre> and <code> elements are avoided because OneNote does not render them correctly. Indentation uses &nbsp; characters, and blockquotes are simulated with styled paragraphs.

What Works

  • Headings, bold, italic, and other text formatting
  • Template fonts applied to headings and body text
  • Ordered and unordered lists
  • Tables with basic structure and template colors
  • Links with clickable URLs
  • KaTeX math and diagram images

Limitations

  • No syntax highlighting in code blocks
  • Code blocks use monospace styling without semantic code elements
  • OneNote may reformat spacing and margins based on its own styles
  • Complex nested content may lose some structure

Email

Email output uses inline-styled HTML for maximum client compatibility. No external CSS, no external images, and no <style> tags. Table-based layouts are used for Outlook compatibility. Works in Gmail, Outlook, Apple Mail, and most other clients.

What Works

  • Headings, bold, italic, and basic text formatting with template colors
  • Links with clickable URLs
  • Ordered and unordered lists
  • Tables (some clients may display these inconsistently)
  • Inline code with monospace styling
  • Callout styling with colored borders
  • KaTeX math and diagram images

Limitations

  • Code blocks may lose formatting in Outlook
  • Table rendering varies across email clients
  • Some email clients strip background colors and advanced CSS
  • Images are referenced by URL, not embedded inline
  • Template font support is partial (depends on client)
Warning
Test your pasted content by sending a test email to yourself before sending to recipients. Email rendering varies significantly across clients and platforms.

Plain Text

The plain text destination strips all formatting and produces clean, unformatted text following RFC 3676 conventions. No template colors, fonts, or styling are applied.

Formatting Conventions

  • H1 becomes ALL CAPS, other headings use plain text
  • Bold and italic markers are stripped
  • Links become text (url) format
  • Lists use - and 1. markers
  • Blockquotes use > prefix
  • Code blocks use 4-space indentation
  • Tables use pipes and dashes alignment
  • Task lists preserve - [x] and - [ ] markers
  • Maximum 2 consecutive blank lines

Limitations

  • All visual formatting (bold, italic, colors) is removed
  • Tables may not align perfectly with variable-width fonts
  • Diagrams, math, and images are excluded entirely
