Looking at the code, it looks like they used existing Python packages to read and parse MS Office formats, not what I expected, seeing that the repo is in Microsoft's org on GitHub I expected them to have used Microsoft's "official" libraries for parsing these formats, through Component Object Model (COM). They used Mammoth for docx (Word) [1][2] Python-pptx for ppt (PowerPoint) [3][4] and Pandas for XSLX (Excel) [5] [1] https://github.com/microsoft/markitdown/blob/70ab149ff1657c327ebd6ca940988f5d3c5d80d0/src/markitdown/_markitdown.py#L495 https://github.com/microsoft/markitdown/blob/70ab149ff1657c3...
