Parse JSON items with different item names into table rows

Hello,

I have the following JSON as a source : 

{
    "statusCode": "OK",
    "statusMessage": "OK",
    "rowCount": 28,
    "totalRowCount": 28,
    "data": [
        {
            "RowIndex": "1",
            "VisitId": "105X1",
            "Score": "82,89",
            "Notes": "",
            "Items": {
                "12563": {
                    "name": "SB",
                    "status": "A",
                    "value": "No"
                },
                "12566": {
                    "name": "BC",
                    "status": "A",
                    "value": "No"
                },
                "12568": {
                    "name": "BV",
                    "status": "A",
                    "value": "No"
                }
            }
        },
        {
            "RowIndex": "2",
            "VisitId": "105Y17",
            "Score": "90,07",
            "Notes": "",
            "Items": {
                "8002": {
                    "name": "TR",
                    "status": "A",
                    "value": "Oui"
                },
                "8091": {
                    "name": "LH",
                    "status": "A",
                    "value": "Oui"
                }
            }
        }
    ]
}

My problem is the field Items.XXXXX with XXXX having a different value everytime, and will have additional values everytime I refresh.

Ideally I want to expand the list Data into this following format in my table : 

RowIndex    VisitId    Score    Notes      Items     Items.name   Items.status    Items.value  

      1            105X1    82,89                   12563           SB                A                    No

      1            105X1    82,89                   12566           BC                A                    No

.....

I tried to apply the following code "Custom1" to my Power Query but it doesn't work because of the field with a different value everytime :

let
Source = Json.Document(File.Contents("XXX")),
#"Converted to Table" = Table.FromRecords({Source}),
#"Expanded data" = Table.ExpandListColumn(#"Converted to Table", "data"),
#"Expanded data1" = Table.ExpandRecordColumn(#"Expanded data", "data", {"RowIndex", "VisitId", "Score", "Notes", "Items"}, {"data.RowIndex", "data.VisitId", "data.Score", "data.Notes", "data.Items"})

 Custom1 = Table.TransformColumns(#"Expanded data1", {"???????", each Table.FromColumns(Record.ToList(_))}),
 

Any help would be appreciated.

Thank you
