Some decent overview docs about xlsx that are substantially less than 6000 pages long 🎉

Yup, there's lots of this sort of stuff there, and it's useful. I started with these, but I kept on introducing bugs with new sheets because I wasn't sure if an element would always be present, or what the universe of relevent attributes for a tag was. So while these are a good place to start eventually the spec is needed :cry:

Interesting to read, in the sense that even reading the docs reveals some about their underlying workbook object. "XlsxWriter is a Python module for creating Excel XLSX files."

Curiously informative. "How do I ...?" from the Spreadsheets section of Microsoft's docs on Open XML SDK:

Good example where you can confirm knowledge about which files do what and which are required:

This seems to be less miserable than reading the spec.
