Excel 文件转 JSON格式对象

将导入的如图所示格式的城乡区划代码的excel文件整理成json格式的对象储存在js文件中：

var PROJECTDISTRICTDATA=[
    {
        "name": "鼓楼区",
        "departid": 320302000000,
        "type": "district",
        "street": [
            {
                "name": "黄楼街道",
                "departid": 320302001000,
                "type": "street",
                "village": [
                    {
                        "name": "华联社区居委会",
                        "departid": 320302001001,
                        "type": "village"
                    }
                ]
            }
        ]
    }
]；
