convert .csv to a .xlsx from CLI

Question

I found this for the opposite conversion Convert xlsx to text CSV via command line only on Linux But I have absolutely no understanding of that line of code. Can anyone tell me how to convert from a csv to a xlsx from the CLI? Thanks in advance for any help.

Answer 1

Maybe you can try unoconv, which uses libreoffice as backend. It can convert between formats really easily:

unoconv -f xls myfile.csv

Sadly it does not support xlsx on Fedora, but supports ooxml - Microsoft Excel 2003 XML [.xml]
