如何解析json中的二维数组

[mrt5121]

{
"expressions": [
"Timeseries",
"Value",
"DataType"
],
"column_names": null,
"data_types": [
"TEXT",
"TEXT",
"TEXT"
],
"timestamps": [
1763604572452
],
"values": [
[
"root.micro_grid.pv_group.pv.total_generation"
],
[
"300.0"
],
[
"DOUBLE"
]
]
}，这是从iotdb查询得到的响应，对于expressions、column_names、timestamps都可以使用acl_json_getElementsByTags获取到节点并取出内容，但是value中的内容如何解析

合理的格式最好是：

{
  "expressions": [
    "Timeseries",
    "Value",
    "DataType"
  ],
  "column_names": null,
  "data_types": [
    "TEXT",
    "TEXT",
    "TEXT"
  ],
  "timestamps": [
    1763604572452
  ],
  "values": [
    "root.micro_grid.pv_group.pv.total_generation",
    "300.0",
    "DOUBLE"
  ]
}
