I have a bunch of .xls and .xlsx files

Each of them contains several sheets (tabs)

I want to programmaticalyy save every sheet as a csv file

I do NOT own any copy of non free software. This is a totally open/free software effort (I'm volunteering here)

I've been thinking of headless LibreOffice or UnoConv. But I don't know where to start from.

Currently I'm using a hack written in python but I'd like to get rid of it

Thanks
