Pandoc Document Conversion Skill Convert documents between formats using pandoc, the universal document converter. Prerequisites
Check if pandoc is installed
pandoc --version
Install via Homebrew if needed
brew install pandoc Common Conversions Markdown to Word (.docx)
Basic conversion
pandoc input.md -o output.docx
With table of contents
pandoc input.md --toc -o output.docx
With custom reference doc (for styling)
pandoc input.md --reference-doc
template.docx -o output.docx
Standalone with metadata
pandoc input.md -s --metadata title = "Document Title" -o output.docx Markdown to PDF
Requires LaTeX - install one of:
brew install --cask basictex # Smaller (~100MB)
brew install --cask mactex-no-gui # Full (~4GB)
After install: eval "$(/usr/libexec/path_helper)" or new terminal
Basic conversion (uses pdflatex)
pandoc input.md -o output.pdf
With table of contents and custom margins
pandoc input.md -s --toc --toc-depth = 2 -V geometry:margin = 1in -o output.pdf
Using xelatex (better Unicode support - box drawings, arrows, etc.)
export PATH = "/Library/TeX/texbin: $PATH " pandoc input.md --pdf-engine = xelatex -V geometry:margin = 1in -o output.pdf PDF Engine Selection: Engine Use When pdflatex Default, ASCII content only xelatex Unicode characters (arrows, box-drawing, emojis) lualatex Complex typography, OpenType fonts Markdown to HTML Critical: Always use -f gfm (GitHub Flavored Markdown) for proper line break and list handling. Standard markdown collapses consecutive lines into paragraphs.
RECOMMENDED: GitHub Flavored Markdown with full styling
pandoc -f gfm -s -H < ( cat << 'STYLE'
<style> body{font-family:-apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,sans-serif;max-width:800px;margin:0 auto;padding:2em;line-height:1.6} h1{border-bottom:2px solid #333;padding-bottom:0.3em} h2{border-bottom:1px solid #ccc;padding-bottom:0.2em;margin-top:1.5em} h3{margin-top:1.2em} ul,ol{margin:0.5em 0 0.5em 1.5em;padding-left:1em} ul{list-style-type:disc}ol{list-style-type:decimal} li{margin:0.3em 0}ul ul,ol ul{list-style-type:circle;margin:0.2em 0 0.2em 1em} table{border-collapse:collapse;width:100%;margin:1em 0} th,td{border:1px solid #ddd;padding:8px;text-align:left} th{background-color:#f5f5f5} code{background-color:#f4f4f4;padding:2px 6px;border-radius:3px} pre{background-color:#f4f4f4;padding:1em;overflow-x:auto;border-radius:5px} blockquote{border-left:4px solid #ddd;margin:1em 0;padding-left:1em;color:#666} </style>STYLE ) input.md -o output.html
Quick version (minimal styling)
pandoc -f gfm -s input.md -o output.html
With hard line breaks (newlines become
)
pandoc -f markdown+hard_line_breaks -s input.md -o output.html
Self-contained (embeds images/CSS)
pandoc
-f
gfm
-s
--embed-resources
--standalone
input.md
-o
output.html
Format Options:
Option
Use When
-f gfm
Default choice - handles lists, line breaks, tables correctly
-f markdown+hard_line_breaks
Force all newlines to become
-f commonmark
Strict CommonMark compliance
HTML for Print-to-PDF (No LaTeX Required)
When LaTeX isn't available, create styled HTML and print to PDF from browser:
Create inline CSS file
cat
/tmp/print-style.css << 'EOF' body { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif; max-width: 800px; margin: 0 auto; padding: 2em; line-height: 1.6; } h1 { border-bottom: 2px solid #333; padding-bottom: 0.3em; } h2 { border-bottom: 1px solid #ccc; padding-bottom: 0.2em; margin-top: 1.5em; } h3 { margin-top: 1.2em; } / Lists - critical for proper rendering / ul, ol { margin: 0.5em 0 0.5em 1.5em; padding-left: 1em; } ul { list-style-type: disc; } ol { list-style-type: decimal; } li { margin: 0.3em 0; } ul ul, ol ul { list-style-type: circle; margin: 0.2em 0 0.2em 1em; } ul ol, ol ol { margin: 0.2em 0 0.2em 1em; } ul ul ul, ol ul ul { list-style-type: square; } / Tables / table { border-collapse: collapse; width: 100%; margin: 1em 0; } th, td { border: 1px solid #ddd; padding: 8px; text-align: left; } th { background-color: #f5f5f5; } / Code / code { background-color: #f4f4f4; padding: 2px 6px; border-radius: 3px; } pre { background-color: #f4f4f4; padding: 1em; overflow-x: auto; border-radius: 5px; } / Other / blockquote { border-left: 4px solid #ddd; margin: 1em 0; padding-left: 1em; color: #666; } @media print { body { max-width: none; } } EOF
Convert with embedded styles (ALWAYS use -f gfm)
pandoc -f gfm input.md -s --toc --toc-depth = 2 -c /tmp/print-style.css --embed-resources --standalone -o output.html
Open and print to PDF (Cmd+P > Save as PDF)
open output.html Word to Markdown
Extract markdown from docx
pandoc input.docx -o output.md
With ATX-style headers
pandoc input.docx --atx-headers -o output.md Useful Options Option Description -s / --standalone Produce standalone document with header/footer --toc Generate table of contents --toc-depth=N TOC depth (default: 3) -V key=value Set template variable --metadata key=value Set metadata field --reference-doc=FILE Use FILE for styling (docx/odt) --template=FILE Use custom template --highlight-style=STYLE Syntax highlighting (pygments, tango, etc.) --number-sections Number section headings -f FORMAT Input format (if not auto-detected) -t FORMAT Output format (if not auto-detected) Format Identifiers Format Identifier Markdown markdown , gfm (GitHub), commonmark Word docx PDF pdf HTML html , html5 LaTeX latex RST rst EPUB epub ODT odt RTF rtf Google Docs Workflow To get markdown into Google Docs with formatting preserved:
1. Convert to docx
pandoc document.md -o document.docx
2. Upload to Google Drive
3. Right-click > Open with > Google Docs
Google Docs imports .docx files well and preserves: Headings Bold/italic Lists (bulleted and numbered) Tables Links Code blocks (as monospace) PSI Document Conversion For PSI documents with tables and complex formatting:
Convert PSI markdown to Word
pandoc PSI-document.md \ --standalone \ --toc \ --toc-depth = 2 \ -o PSI-document.docx
Open for review
open PSI-document.docx Troubleshooting Lists/Lines Running Together (HTML) If bullet points, numbered lists, or consecutive lines merge into one paragraph: Cause: Standard markdown treats consecutive lines as one paragraph. Lists need blank lines before them. Fix: Use GitHub Flavored Markdown ( -f gfm ):
Always use -f gfm for reliable formatting
pandoc -f gfm -s input.md -o output.html
For documents where newlines should be
tags
pandoc -f markdown+hard_line_breaks -s input.md -o output.html Why this happens: Standard markdown: Line 1\nLine 2 →
Line 1 Line 2
(merged)
GFM: Better list detection, handles edge cases
+hard_line_breaks
:
Line 1\nLine 2
→
Line 1
Line 2
(preserved)
Tables Not Rendering
Pandoc requires proper markdown table syntax:
|
Header 1
|
Header 2
|
|
|
| | Cell 1 | Cell 2 | Code Blocks Missing Highlighting Use fenced code blocks with language identifier: ```python def example(): pass
PDF Generation Fails
"pdflatex not found" - Install LaTeX: ```bash
Smaller option (~100MB)
brew install --cask basictex
Full option (~4GB)
brew install --cask mactex-no-gui
After install, update PATH
eval "$(/usr/libexec/path_helper)"
Or open a new terminal
Unicode character errors (box-drawing, arrows, emojis):
Use xelatex instead of pdflatex
export PATH = "/Library/TeX/texbin: $PATH " pandoc input.md --pdf-engine = xelatex -o output.pdf No LaTeX available - Use HTML print-to-PDF workflow: pandoc input.md -s --toc -o output.html open output.html
Then Cmd+P > Save as PDF
Self-Test
Verify pandoc installation
