There are plenty of websites and GUI apps that provide similar tools, but I wanted something that stays in the terminal and works with pipes, e.g.:

  curl -s 'https://dummyjson.com/products?limit=5&select=title,price,brand' \
    | swk query json '$.products' \
    | swk format json2table
~50 commands to convert, format, encode, escape, generate, inspect, query, diff. Single Go binary, zero dependencies.
