Use this. U can check the output in the console of the browser if u need.

function reSortRoot(root, value_key) {
                //console.log("Calling");
                for ( var key in root) {
                    if (key == "key") {
                        root.name = root.key;
                        delete root.key;
                    }
                    if (key == "values") {
                        root.children = [];
                        for (item in root.values) {
                            root.children.push(reSortRoot(root.values[item],
                                    value_key));
                        }
                        delete root.values;
                    }
                    if (key == value_key) {
                        root.value = parseFloat("1");
                        delete root[value_key];
                    }
                }
                return root;
            } 

            var testdata=[
                          { "dep": "d1", "name": "name1", "size": "size1" },
                          { "dep": "d1", "name": "name2", "size": "size2" },
                          { "dep": "d2", "name": "name1", "size": "size3" },
                          { "dep": "d2", "name": "name1", "size": "size4" }
                      ];

            var testJson = d3.nest()
            .key(function(d)  { return d.dep; })
            .entries(testdata); 
             console.log(testJson);

            var testRoot={};
            testRoot.key = "Information";
            testRoot.values = testJson;
            testRoot = reSortRoot(testRoot, "name");

             console.log(testRoot);
