Your favorite JSON parsing extension?

What’s your favorite marketplace extension to clean up JSON?

I often have to read through messy JSON (e.g. from third party logs, JSON stored in a Postgres database, etc.) and am wondering what’s the best way to just paste it in a blank new file and have it look good.

I currently use Ctrl+K for this but it seems like overkill.

Turns out Shift + Alt + F (or Shift + Option + F in Mac) does this.
