How to automatically split a large CSV file into smaller files?

[herbst010]

Hello everyone, I have a single .csv file with 8 million rows, and I'd like to split it into multiple .csv files of 1 million rows each, automatically saving them locally on .csv format. Is it possible to do this with a Python script on Visidata? If so, could you help me create it?

There are better tools than VisiData to do this for csv, assuming none of the fields have newlines in them. Use the POSIX tools head and split.
