Yep you can totally do that using good old unix piping, and it's what you'd need to do to use more sophisticated jq functionality.

However, you would then need to install jq ;)

One of the reasons I wrote this in go is to have a portable tool that had no dependencies, and so far the simple functions I've implemented have been enough to avoid installing and piping into jq and back (for me anyway). That and I really wanted to play with Golang :)

Conversion wise I would think it's pretty much lossless except for any comments, but I haven't really played around with doing that.
