Dynamically retrieve relevant data from JSON and copy to SQL Table through Azure Data Factory

I am looking for an easy way to dynamically copy data from JSONs to SQL tables. The JSONs all have the same setup where the data is mentioned after fields like so:

  {
    "name": "Employees",
    "description": "Employeedata",
    "fields": [
      {
        "id": "EmployeeId",
        "fieldId": "U001",
        "dataType": "string",
        "label": "Employee",
        "length": 15,
        "controlType": 5,
        "decimals": 0,
        "decimalsFieldId": ""
      },
      {
        "id": "PersonId",
        "fieldId": "U003",
        "dataType": "string",
        "label": "EmpID",
        "length": 15,
        "controlType": 5,
        "decimals": 0,
        "decimalsFieldId": ""
      },
      {
        "id": "EmployerId",
        "fieldId": "U002",
        "dataType": "string",
        "label": "Employer",
        "length": 15,
        "controlType": 5,
        "decimals": 0,
        "decimalsFieldId": ""
      }
    ]
  }
]

The main structure is the same, so the relevant data is always after the fields property. However, the columns and corresponding data differs for each JSON.

When I perform the copy activity as is, the table ends up like this:

Name Description
Employees Employeedata

What I want is something like this:

id fieldId datatype label length controlType decimals decimalsFieldId
EmployeeId U001 string Employee 15 5 0
PersonId U003 string EmpID 15 5 0
EmployerId U002 string Employer 15 5 0

I am looking for a way to copy only the arrays after fields to an SQL table without having to manually assign a mapping for each JSON.

Move JSON file to SQL DB by the copy activity, provide JSON as source.

enter image description here

Provide SInk as SQL database.

(enter image description here)

In the mapping field need to import schema and enable Advance editor field, need to select options in Collection reference field.

(enter image description here)

Delete these column fields to get expected result as per the requirement.

(enter image description here)

Result get as we expected in SQL Database.
