- What: Python library that converts documents to Markdown
- By: Microsoft (MIT license, fully open source)
- Install:

- Use case: AI pipelines, documentation, knowledge management
Why Microsoft Built MarkItDown
Microsoft's AI teams needed a reliable way to convert diverse document formats into text that large language models could process. Existing tools were either:
- Too simple — basic text extraction that lost all structure
- Too complex — heavy dependencies, slow processing, unreliable output
- Too expensive — commercial APIs charging per page
MarkItDown fills the gap: fast, reliable, open-source, and format-aware.
Supported Formats
MarkItDown handles an impressive range:
| Format | Extension | What's Extracted |
|---|---|---|
.pdf | Text, headings, tables, lists | |
| Word | .docx | Full document structure |
| PowerPoint | .pptx | Slide content and notes |
| Excel | .xlsx, .xls | Tables with headers |
| CSV | .csv | Markdown tables |
| HTML | .html | Semantic content |
| EPUB | .epub | Chapter structure |
| JSON | .json | Formatted code blocks |
| XML | .xml | Content hierarchy |
| Images | .jpg, .png | EXIF metadata |
| Audio | .wav, .mp3 | File metadata |
| Archives | .zip | Contents listing |
How to Use MarkItDown (Python)
from markitdown import MarkItDown
md = MarkItDown()
result = md.convert("report.pdf")
print(result.text_content)
Three lines. That's the entire API for basic usage. Install with:
pip install 'markitdown[all]'
The [all] extra installs dependencies for every supported format. You can also install selectively if you only need specific formats.

MarkItDown vs. Pandoc: Pandoc supports more output formats but doesn't handle PDF extraction as well. MarkItDown is focused: documents in, Markdown out.
MarkItDown vs. Docling: Docling (by IBM) is another document converter gaining traction. It focuses more on scientific documents and offers layout analysis. MarkItDown is more general-purpose with broader format support and a simpler API.
