sure can do, if you already use that shell [1], but personally I like specific tools for specific jobs such as jq [2], fx, csvq [3] etc, there's value in decoupling shells from utils (modularity, speed, innovation etc).
[1] I don't but tempted to try, like its data-types concept
No the output is a table object, you can apply other operations to it like sort, etc. the shell displays them in this ascii art way at the end but you can also write to files in various formats.
