Usage

Reformat

SPC m = will reformat the whole buffer or the active region. Use numerical prefix argument to specify a different indentation than js-indent-level. Use the universal prefix argument to print decoded strings, for instance:

{"name":"foo\"bar","nick":"foo \u00e4 bar","description":"<pre>\nbaz\n</pre>","home":"/home/foobar"}

Will be reformated:

{
  "name": "foo\"bar",
  "nick": "foo ä bar",
  "description": "<pre>
  baz
  </pre>",
  "home": "/home/foobar"
}

Display navigable hierarchy

SPC m h h displays the hierarchy for the whole JSON document or the active region. Use the universal prefix argument SPC u SPC m h h to create the hierarchy for the JSON after the point.
