Take potentially dangerous PDFs, and convert them to safe PDFs

I wonder if the Excel export is retaining a lot of document structure in the event that it's imported back into Excel again at a later point.

Fun trivia: XLSX, DOCX, PPTX are just XML files, you can rename them to ".XML" file extension, and open them in notepad to see their raw contents.

But you can use qpdf or PDFEdit to interpret a PDF's raw code.

And thus, you can compare the raw XLSX (XML) vs raw PDF.
