For those that don’t know - xlsx files are just zips. Change the extension and open them to see all the xml lurking within. For what it’s worth we use xlsxwriter and are happy with it.

I've also used xlswriter and had the same experience - very happy with it. I used it to generate bar and pie charts on one of the sheets.

same with docx. We don't use any docx libraries to generate docx files from templates. we just: unzip, string replace, zip
