JSON.stringify includes a formatting argument:

> The space argument may be used to control spacing in the final string. If it is a number, successive levels in the stringification will each be indented by this many space characters (up to 10). If it is a string, successive levels will indented by this string (or the first ten characters of it).

 Is that enough formatting for what you need?
