Build JSON with this structure

[Leandro Feder]

Hello

I need to create a json in the following structure:

{
    "Value1": {
        "Build": {
            "1": {
                "t_inst": {
                    "Type": "Gold",
                    "Key": "15",
                    "size": "big"
                },
                "1_avg": {
                    "Type": "Green",
                    "Key": "11",
                    "size": "big"
                },
                "2_avg": {
                    "Type": "Blue",
                    "Key": "21",
                    "size": "big"
                }
            },
            "2": {
                "t_inst": {
                    "Type": "Gold",
                    "Key": "15",
                    "size": "big"
                },
                "1_avg": {
                    "Type": "Green",
                    "Key": "11",
                    "size": "big"
                },
                "2_avg": {
                    "Type": "Blue",
                    "Key": "21",
                    "size": "big"
                }
            }
        }
    },
    "Value2": {
        "Build": {
            "1": {
                "t_inst": {
                    "Type": "Grey",
                    "Key": "22",
                    "size": "small"
                },
                "1_avg": {
                    "Type": "Yellow",
                    "Key": "8",
                    "size": "big"
                },
                "2_avg": {
                    "Type": "Blue",
                    "Key": "21",
                    "size": "big"
                }
            }
        }
    }
}

I've searched several forums, but none I've seen have as many layers as I need.

Could someone help me?
