What it is

fx is a command-line program that lets you browse JSON data in an interactive terminal view and run processing on it. It is useful when raw JSON from an API or file is hard to read as plain text. The README is brief and points to fx.wtf for full documentation.

  • Browse a large JSON response from a web API in a readable, collapsible view
  • Explore the structure of an unfamiliar JSON file from the command line
  • Process JSON data from a terminal pipeline (see fx.wtf for specifics)

Great for

  • Developers who work with JSON output from APIs or log files in the terminal
  • People who want to explore a JSON document interactively instead of reading raw text
  • Users who prefer keyboard-driven terminal tools

Not ideal for

  • People who need a graphical JSON editor, since fx runs in the terminal
  • Anyone needing details on specific processing syntax, since the README does not describe it and the documentation lives on the external site
