Technical Principles of MarkItDown
- File parsing: Uses different parsers to read and parse the content of various file formats.
- Text extraction and conversion：
- For document-type files (such as Word, Excel, PowerPoint), converts document content into plain text while preserving structured information (such as headings, lists, etc.) in a format suitable for Markdown.
- For image files, uses OCR technology (optical character recognition) to recognize text in images and convert it into text format.
- Metadata processing: For images and audio files, extracts EXIF metadata, a type of standardized information stored in files, including the file's creation time, author, device information, and more.
- Speech transcription: For audio files, uses speech recognition technology to transcribe speech content into text.
