I see that for word documents both the old format .doc and the new format .docx are supported, and similarly for excel (.xls and xslx) but for powerpoint files only the new format is supported. Is there a reason for that? If not it seems like an obvous suggestion to implement if only for completeness sake.
If there's a tool out there that can parse the old Powerpoint format, feel free to create a PR. I think the CLI tool of LibreOffice can, but perhaps there are better options.
