I usually use csvkit (<a href="https://csvkit.readthedocs.io/en/1.0.1/index.html" rel="nofollow">https://csvkit.readthedocs.io/en/1.0.1/index.html</a>). There are commands to list the columns, filter, browse the data in a somewhat formatted way with less. Typing the commands is a huge pain though, and I would be very interested in a tool that could <i>instantly</i> pop open and let me peruse. Excel can take minutes to load and eagerly does a lot of unhelpful formatting on things like dates and decimals.<p>That being said I would never want to (and often legally cannot) etl my data to some third party. That would be terribly slow. But I would happily pay for a nice desktop tool to do it for me; command line or GUI.
