通过后台配置规则映射，从mongodb按规则导出xlsx数据，具体实现不知道怎么写？

Question

这是我想定义的规则格式

[
  {
    "field_title":"目标"
    "field_value":"data.data.items[].target"
  },
  {
    "field_title":"日期"
    "field_value":"data.data.items[].display_date"
  },
    {
    "field_title":"总数"
    "field_value":"data.data.total"
  },
]

通过上面的字段定义，因为要导出excel，所以得有字段映射，才能动态把mongodb的数据按规则转换成xlsx表格数据，具体转换代码我如何写？以下是mongodb 类似json的数据

  "_id": {
    "$oid": "66d58a4ffd7ece5c431a26ee"
