The technical principles of MarkItDown
- File parsingUse different parsers to read and parse the content of various file formats.
- Text extraction and conversion:
- For document files (such as Word, Excel, PowerPoint), the document content is converted into plain text while retaining structured information (such as headings, lists, etc.) to adapt to Markdown format.
- For image files, OCR (Optical Character Recognition) technology is used to recognize the text in the image and convert it into text format.
- Metadata processingFor image and audio files, extract EXIF metadata, a standardized information stored in the file, including the file's creation time, author, device information, etc.
- Speech transcriptionFor audio files, speech recognition technology is used to transcribe the speech content into text.
