It's the *best*. Small, relatively lightweight, and does the job in
milliseconds. The output is limited to CSV though.

Not relevant. Input is xlsx.

Suggesting using Java to parse XML in ZIP archive can be considered
cruel and unusual punishment in certain countries. Besides, these are
library and a documentation. Implementation of working parser is left as
an exercise to a reader.

That one's good, with one *litte* problem.
Making the thing output any sensible result is *very* painful.

Don't. Just don't. unoconv is an ugly python script that launches
headless Libreoffice and feeds the file to a resulting web-service.
It has all the disadvantages of Libreoffice (CPU/Memory consumption,
abysmal parsing speed, Libreoffice format limitations), and a single
gain - an ability to batch-convert files.

If Libreoffice is unable to open it - unoconv will do one absolutely no

Also, 'apt search xlsx'.
