Microsoft has released MarkItDown, a free Python utility. It converts various file formats into Markdown text, making it incredibly easy to integrate with LLMs and text analysis pipelines.

The tool supports a wide array of file types, including PDF, PowerPoint, Word, Excel, images (extracting EXIF metadata and OCR), audio (extracting metadata and transcribing speech), HTML, text formats like CSV/JSON/XML, ZIP archives (traversing contents), as well as YouTube links and EPub files. Conversion requires only 4 lines of code—for instance, turning a Word document or an Excel spreadsheet into Markdown. For images, it can even leverage the OpenAI API to use LLMs for generating image descriptions.
