Original Data

{
    "a": 123,
    "b": "xxx",
    "c": [
        [
            1,
            2,
            3
        ],
        [
            1,
            null,
            3
        ]
    ]
}

Result

type RootObject struct {
    A int           `json:"a"`
    B string        `json:"b"`
    C []interface{} `json:"c"`
}

Expect

type RootObject struct {
    A int           `json:"a"`
    B string        `json:"b"`
    C [][]interface{} `json:"c"`
}
