JSON to CSV using jq or python [closed]

Need help converting this JSON and using a specific element of the Column Dimension as the Column header line in CSV using jq

Input JSONyour text

{"Columns": [        {"Id": "ItemName","IsEditable": false        },        {"Id": "Date","IsEditable": false        },        {"Id": "Qty","IsEditable": false        }    ],"Rows": [        {"Values": ["ITEM1","10-MAY-2024","100"            ]        },        {"Values": ["ITEM2","20-MAY-2024","200"            ]        },        {"Values": ["ITEM3","30-MAY-2024","400"            ]        }    ],"QueryHandle": {"QueryID": "00101","Worksheet": {"Name": "Test20","Scope": "NA"        },"WorkAlloc": "2024-MAY"    },"RowCount": 3}

Required Output in CSV format ( I only the data below and the rest of the elements in JSON to be ignored).

The header columns come from .Columns[]|.Id

ItemName, Date, Qty"Item1","10-MAY-2024","100""Item2","20-MAY-2024","200""Item3","20-MAy-2024","400"
