Markitdown

MarkItDown

Overview

MarkItDown is a Python utility that converts various file formats into Markdown format, optimized for use with large language models and text analysis pipelines. It preserves document structure (headings, lists, tables, hyperlinks) while producing clean, token-efficient Markdown output.

When to Use This Skill

Use this skill when users request:

• Converting documents to Markdown format
• Extracting text from PDF, Word, PowerPoint, or Excel files
• Performing OCR on images to extract text
• Transcribing audio files to text
• Extracting YouTube video transcripts
• Processing HTML, EPUB, or web content to Markdown
• Converting structured data (CSV, JSON, XML) to readable Markdown
• Batch converting multiple files or ZIP archives
• Preparing documents for LLM analysis or RAG systems

Core Capabilities

1. Document Conversion

Convert Office documents and PDFs to Markdown while preserving structure.

Supported formats:

• PDF files (with optional Azure Document Intelligence integration)
• Word documents (DOCX)
• PowerPoint presentations (PPTX)
• Excel spreadsheets (XLSX, XLS)

Basic usage:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("document.pdf")
print(result.text_content)

Command-line:

bashCopy code
markitdown document.pdf -o output.md

See references/document_conversion.md for detailed documentation on document-specific features.

2. Media Processing

Extract text from images using OCR and transcribe audio files to text.

Supported formats:

• Images (JPEG, PNG, GIF, etc.) with EXIF metadata extraction
• Audio files with speech transcription (requires speech_recognition)

Image with OCR:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("image.jpg")
print(result.text_content)  # Includes EXIF metadata and OCR text

Audio transcription:

pythonCopy code
result = md.convert("audio.wav")
print(result.text_content)  # Transcribed speech

See references/media_processing.md for advanced media handling options.

3. Web Content Extraction

Convert web-based content and e-books to Markdown.

Supported formats:

• HTML files and web pages
• YouTube video transcripts (via URL)
• EPUB books
• RSS feeds

YouTube transcript:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("https://youtube.com/watch?v=VIDEO_ID")
print(result.text_content)

See references/web_content.md for web extraction details.

4. Structured Data Handling

Convert structured data formats to readable Markdown tables.

Supported formats:

• CSV files
• JSON files
• XML files

CSV to Markdown table:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("data.csv")
print(result.text_content)  # Formatted as Markdown table

See references/structured_data.md for format-specific options.

5. Advanced Integrations

Enhance conversion quality with AI-powered features.

Azure Document Intelligence: For enhanced PDF processing with better table extraction and layout analysis:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown(docintel_endpoint="<endpoint>", docintel_key="<key>")
result = md.convert("complex.pdf")

LLM-Powered Image Descriptions: Generate detailed image descriptions using GPT-4o:

pythonCopy code
from markitdown import MarkItDown
from openai import OpenAI

client = OpenAI()
md = MarkItDown(llm_client=client, llm_model="gpt-4o")
result = md.convert("presentation.pptx")  # Images described with LLM

See references/advanced_integrations.md for integration details.

6. Batch Processing

Process multiple files or entire ZIP archives at once.

ZIP file processing:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()
result = md.convert("archive.zip")
print(result.text_content)  # All files converted and concatenated

Batch script: Use the provided batch processing script for directory conversion:

bashCopy code
python scripts/batch_convert.py /path/to/documents /path/to/output

See scripts/batch_convert.py for implementation details.

Installation

Full installation (all features):

bashCopy code
uv pip install 'markitdown[all]'

Modular installation (specific features):

bashCopy code
uv pip install 'markitdown[pdf]'           # PDF support
uv pip install 'markitdown[docx]'          # Word support
uv pip install 'markitdown[pptx]'          # PowerPoint support
uv pip install 'markitdown[xlsx]'          # Excel support
uv pip install 'markitdown[audio]'         # Audio transcription
uv pip install 'markitdown[youtube]'       # YouTube transcripts

Requirements:

• Python 3.10 or higher

Output Format

MarkItDown produces clean, token-efficient Markdown optimized for LLM consumption:

• Preserves headings, lists, and tables
• Maintains hyperlinks and formatting
• Includes metadata where relevant (EXIF, document properties)
• No temporary files created (streaming approach)

Common Workflows

Preparing documents for RAG:

pythonCopy code
from markitdown import MarkItDown

md = MarkItDown()

# Convert knowledge base documents
docs = ["manual.pdf", "guide.docx", "faq.html"]
markdown_content = []

for doc in docs:
    result = md.convert(doc)
    markdown_content.append(result.text_content)

# Now ready for embedding and indexing

Document analysis pipeline:

bashCopy code
# Convert all PDFs in directory
for file in documents/*.pdf; do
    markitdown "$file" -o "markdown/$(basename "$file" .pdf).md"
done

Plugin System

MarkItDown supports extensible plugins for custom conversion logic. Plugins are disabled by default for security:

pythonCopy code
from markitdown import MarkItDown

# Enable plugins if needed
md = MarkItDown(enable_plugins=True)
