javascript - Convert regular json to flare.json for d3.js? -

i have json so:

{ "a": {     "x": {         "y": {             "a": {},              "z": {},              "b": {}         }     },      "c": {},      "b": {         "c": {             "d": {}         }     },      "d": {},       ...     } } 

is there quick way convert flare.json format?

like so:

{ "name":"a", "children":[       {       "name":"x",       "children":             {               "name":"y",               "children":[{"name":"a", "size":0},{"name":"z","size":0},{"name":"b","size":0}]  ... } 

thank you.

i have come series of regex transforms this.

 #replace-this      #with-this    ^\s*"             \{"name":"   : \{\},           \},   : \{\}            \}   ": \{$            ","children":\[   ^\s*\},           \]\},   ^\s*\}            \]\}                  #in order 

and delete first , last line (should { , ]} )

on applying these regex transforms,

this:

{ "a": { "x": {     "y": {         "a": {},          "z": {},          "b": {}     } },  "c": {},  "b": {     "c": {         "d": {}     } },  "d": {}  } 

}

will become this:

{ "name": "a", "children": [{     "name": "x",     "children": [{         "name": "y",         "children": [{             "name": "a"         },         {             "name": "z"         },         {             "name": "b"         }]     }] }, {     "name": "c" }, {     "name": "b",     "children": [{         "name": "c",         "children": [{             "name": "d"         }]     }] }, {     "name": "d" }] } 

which can used of d3js examples.
