Why Convert PowerPoint Presentations to Markdown?

Markdown is lightweight, portable, and ideal for:

  • Static documentation sites (e.g., Hugo, Jekyll)
  • Technical blogs and dev wikis
  • Version-controlled content in Git
  • Reusing slide content in other formats

By converting .pptx files to .md, you get structured text output that can be reviewed, versioned, or republished easily—without relying on binary Office formats.

Manual vs Automated Conversion

Manually copying text from slides into Markdown is:

  • Time-consuming
  • Inconsistent across slide formats
  • Prone to formatting errors

With Openize.MarkItDown, you automate this process with a CLI or API, maintaining slide titles, bullet points, and even images when supported.

What Is Openize.MarkItDown?

Openize.MarkItDown is a Python-based tool that uses Aspose.Slides combined with custom strategies to transform PowerPoint slides into Markdown documents.

Core Features

  • Extracts content from .pptx files into Markdown
  • Preserves titles, bullet points, speaker notes, and images
  • Batch processing of multiple presentations
  • Supports CLI and Python API
  • Designed using Factory + Strategy Pattern
  • Lightweight, modular, and extensible

Installing Openize.MarkItDown

Clone the repository and install the package locally:

git clone https://github.com/openize-com/openize-markitdown-python.git
cd openize-markitdown-python
pip install .

How to Convert PowerPoint to Markdown

To convert a presentation from the command line:

markitdown convert /path/to/presentation.pptx --output /path/to/output.md

To convert a directory of .pptx files recursively:

markitdown convert ./slides/ --output ./markdown/

Each slide deck is converted into a corresponding Markdown file with structured content blocks.

Example Use Case: Documentation from Slide Decks

Let’s say your team uses PowerPoint for internal presentations or technical architecture overviews. Instead of manually rewriting this content for documentation sites:

  1. Use the MarkItDown class to load .pptx files
  2. Specify an output directory for Markdown
  3. Instantiate the converter with format set to PPTX
  4. Run the transformation process
  5. Output clean .md files, ready to publish

Sample code:

from openize.markitdown.core import MarkItDown

# Define input file and output directory
input_file = "report.docx"
output_dir = "output_markdown"

# Create MarkItDown instance
converter = MarkItDown(output_dir)

# Convert document and send output to LLM
converter.convert_document(input_file, insert_into_llm=False)

print("Conversion completed.")

Advanced Features

  • Pluggable format support (Word, Excel, PDF, and more)
  • Factory + Strategy architecture for easy extension
  • Cross-platform path handling (Windows/Linux/macOS)
  • Robust error handling and logging
  • Separation of CLI and API layers for future integrations
