How to output an object as a readable string with formatting (structured like with <pre>) ?

No jQuery possible.

My object looks like this using console.log.

Object
   title: "Another sting"
   type: "tree"
   options: Object
      paging: "20"
      structuretype: "1"
   columns: Object
      ...
   description: "This is a string"
   ...

What is the best to convert it to a structured string?

My attempt:

I tried using stringify() to get the JSON structure. I could then write my own parser, but maybe there are already any implementations?

    JSON.stringify includes a formatting argument:

    JSON.stringify(value[, replacer [, space]])

    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).

    Using a tab character mimics standard pretty-print appearance

    Is that enough formatting for what you need? E.g. try:

     JSON.stringify( object, null, 2 );

    Otherwise, http://code.google.com/p/google-code-prettify/ is a standalone JSON to HTML pretty printer. Used by stackoverflow and google code, I believe.
