[hoc]

It somehow feels that one has to come up with a tailored strategy for each CVS import that contains decimal numbers, dates and/or other data with dots in them. Most of the time I end up regexing my way out of the failing (and different) attempts the different build-in options in Excel deliver. LibreOffice is better, Apple's Numbers partially worse in that regard. Funny to see these things in that state in 2025.

Discussing number data with current LLMs also does not seem right at the moment. Not sure if simple column-specific conversion tasks might work.
