I think the answer is going to depend on what you're going to do with that CSV
file.

CSV files are just plain text. You can have as many lines as you want in that
kind of file.

But if you're going to import the data into excel into one worksheet, then
you're (Currently!) limited to 64k rows/lines.

If you're going to bring the data into a different application, then you'll be
limited by that application's rules.
