Every object has to be named inside the parent object:

{ "data": {
    "stuff": {
        "onetype": [
            { "id": 1, "name": "" },
            { "id": 2, "name": "" }
        ],
        "othertype": [
            { "id": 2, "xyz": [-2, 0, 2], "n": "Crab Nebula", "t": 0, "c": 0, "d": 5 }
        ]
    },
    "otherstuff": {
        "thing":
            [[1, 42], [2, 2]]
    }
  }
}

So you cant declare an object like this:

var obj = {property1, property2};

It has to be

var obj = {property1: 'value', property2: 'value'};

I successfully solved my problem. Here is my code:

The complex JSON object:

The jQuery code to grab the data and display it on my webpage:

$(document).ready(function() {
var items = [];

$.getJSON('labOrders.json', function(json) {
  $.each(json.medications, function(index, orders) {
    $.each(this, function() {
        $.each(this, function() {
            items.push('<div class="row">'+this.name+"\t"+this.strength+"\t"+this.dose+"\t"+this.route+"\t"+this.sig+"\t"+this.pillCount+"\t"+this.refills+'</div>'+"\n");
        });
    });
  });

  $('<div>', {
    "class":'loaded',
    html:items.join('')
  }).appendTo("body");

});

});

This won't give the exact result you want but I think it's usable:

var fileArray = [
  { name: "file1", path: "/main/file1" },
  { name: "file2", path: "/main/folder2/file2" },
  { name: "file4", path: "/main/folder3/file4" },
  { name: "file5", path: "/main/file5" },
  { name: "file6", path: "/main/file6" }
];  

var tree = fileArray.reduce(function (b, e) {
  var pathbits = e.path.split("/");
  var r = b;
  for (var i=1; i < pathbits.length - 1; i++) {
    bit = pathbits[i];
    if (!r[bit]) r[bit] = {};
    r = r[bit];
  }
  if (!r.files) r.files = [];
  r.files.push(e.name);
  return b;
}, {});

console.log(tree);
