JSON "prettifiers" produce unnecessarily long JSON...

Sounds familiar? This VS Code extension does the right thing by formatting your code snippets in a compact, but still pretty form.

1. Select a JSON text in any file type,
2. Invoke command runner (with Ctrl+Shift+P on Windows or Cmd+Shift+P on Mac)
3. Type command name: Format: Compact Pretty JSON

Enjoy.
