MarkItDown Skill
Microsoft's Python utility for converting various file formats to Markdown for LLM and text analysis pipelines.
Overview
MarkItDown converts documents while preserving structure (headings, lists, tables, links). It's optimized for LLM consumption rather than human-readable output.

Command-Line Usage
# Basic conversion
markitdown document.pdf > output.md
# Specify output file
markitdown document.pdf -o output.md

Python API
from markitdown import MarkItDown
# Basic conversion
md = MarkItDown()
result = md.convert("document.xlsx")
print(result.text_content)
# With LLM for image descriptions
from openai import OpenAI
client = OpenAI()
md = MarkItDown(
llm_client=client,
llm_model="gpt-4o",
llm_prompt="Describe this image in detail"
)
result = md.convert("image.jpg")
print(result.text_content)
# With Azure Document Intelligence
md = MarkItDown(docintel_endpoint="<your-endpoint>")
result = md.convert("complex-document.pdf")
print(result.text_content)
Common Use Cases
Batch Convert Directory
from markitdown import MarkItDown
from pathlib import Path
md = MarkItDown()
input_dir = Path("./documents")
output_dir = Path("./markdown")
output_dir.mkdir(exist_ok=True)
for file in input_dir.glob("*"):
if file.is_file():
try:
result = md.convert(str(file))
output_file = output_dir / f"{file.stem}.md"
output_file.write_text(result.text_content)
print(f"Converted: {file.name}")
except Exception as e:
print(f"Failed: {file.name} - {e}")
Process for LLM Context
from markitdown import MarkItDown
def prepare_for_llm(file_path: str) -> str:
"""Convert document to LLM-ready markdown."""
md = MarkItDown()
result = md.convert(file_path)
# Add source reference
content = f"# Source: {file_path}\n\n{result.text_content}"
return content
# Use with your LLM
context = prepare_for_llm("report.pdf")
Extract YouTube Transcript
# CLI
markitdown "https://www.youtube.com/watch?v=VIDEO_ID" > transcript.md
# Python
from markitdown import MarkItDown
md = MarkItDown()
result = md.convert("https://www.youtube.com/watch?v=VIDEO_ID")
print(result.text_content)
Image OCR with AI Description
from markitdown import MarkItDown
from openai import OpenAI
# Initialize with LLM support
client = OpenAI()
md = MarkItDown(
llm_client=client,
llm_model="gpt-4o"
)
# Convert image with AI description
result = md.convert("screenshot.png")
print(result.text_content)
Convert Jupyter Notebook
from markitdown import MarkItDown
md = MarkItDown()
result = md.convert("analysis.ipynb")
print(result.text_content) # Code cells, outputs, markdown
Extract Wikipedia Content
from markitdown import MarkItDown
md = MarkItDown()
result = md.convert("https://en.wikipedia.org/wiki/Python")
print(result.text_content) # Main article content only
Parse RSS Feed
from markitdown import MarkItDown
md = MarkItDown()
result = md.convert("https://example.com/feed.xml")
print(result.text_content) # Feed entries as markdown
Plugin System
MarkItDown supports third-party plugins for extended functionality.
# List installed plugins
markitdown --list-plugins
# Enable plugins during conversion
markitdown --use-plugins document.pdf
# Enable plugins in Python
md = MarkItDown(enable_plugins=True)
result = md.convert("document.pdf")
Search GitHub for
#markitdown-pluginto find available plugins.
MCP Server Integration
MarkItDown offers an MCP (Model Context Protocol) server for integration with LLM applications like Claude Desktop.
# Install MCP server
pip install markitdown-mcp
# Or from source
git clone https://github.com/microsoft/markitdown.git
cd markitdown/packages/markitdown-mcp
pip install -e .
See markitdown-mcp for configuration details.
Docker Usage
# Build image
docker build -t markitdown:latest .
# Convert file
docker run --rm -i markitdown:latest < document.pdf > output.md
Troubleshooting
| Issue | Solution |
|-------|----------|
| Missing dependencies | Install with pip install 'markitdown[all]' |
| PDF extraction fails | Try Azure Document Intelligence for complex PDFs |
| Image text not extracted | Ensure OCR dependencies installed or use LLM mode |
| Large file timeout | Process in chunks or use streaming |
| Plugin not found | Run markitdown --list-plugins to verify installation |
Common Errors
# ModuleNotFoundError for specific format
