FX is a command-line JSON data file processing tool. It can be installed via npm, brew or downloaded as a standalone binary. It can work in two modes: cli and interactive.
fx comes in handy with a curl command. If you have some API which returns JSON and you want to dig into the structure or just see it, pipe JSON into fx.
fx has a really neat interactive mode for digging into JSON.
