I have a script which generates a CSV file using a bunch of print statements. The columns are hostnames and some numbers, so it is never going to contain commas or newlines. This will be perfectly valid CSV every time. That’s why CSV is absolutely beautiful - there is a huge number of applications that people really care about, and their data is constrained enough that there is not need to care about CSV escaping and need for any third party libraries. Creating XSLX file by hand is possible, but this will be a large amount of code and I wouldn’t include this in my script, it would need to be a separate library - which means build system support, learning the API etc...
