The shell is a very powerful REPL for incremental development, so you can often do things more rapidly by looking with `xsv headers`, then joining with `xsv join | xsv select | head | xsv table` than using python or sqlite. I definitely used to use `sqlite` for every CSV before and I've shifted to using `xsv`. If I want to do any heavy lifting I'm going to pop it into PostgreSQL anyway. Crucial feature is that it's easy to pop some `xsv` pipeline in the middle of your `for i in ...` or `find . -print0 | xargs -0`.
