From https://www.joelonsoftware.com/2008/02/19/why-are-the-microsoft-office-file-formats-so-complicated-and-some-workarounds/ about the old formats:
> *These are binary formats, so loading a record is usually a matter of just copying (blitting) a range of bytes from disk to memory, where you end up with a C data structure you can use. There’s no lexing or parsing involved in loading a file. Lexing and parsing are orders of magnitude slower than blitting.* Probably an old .ppt is difficult to write, but a .pptx is probably just a bunch of .xml compressed with .tar.gzip or zip, and a fancy extension. (I didn't try myself, but I remember to have read something like that.) I used a few times the trick to just write a html file with a few of the custom properties of Office and send it as a .xls or .doc . It works, better than I expected.
