If you come across an edge case that tv does not handle then let me know. I will add a tests csv file as part of the current portfolio of test csvs. https://github.com/alexhallam/tv/tree/main/data

I have been using tv now for a couple months at work. It has been working well on the data I see. If you find edge cases then please open an issue with an example csv.

Pretty well, I'd guess. It uses a well-tested CSV library.
