How to validate data in Ms Access Recordset using VBA

Dear All;
After getting more information here, I think there is need to validate the data before storing in a stagnant table in Ms access. I’m not sure about this topic frankly its new to me , I’m just try to see whether it will work.

I want to check whether Set rs = db.OpenRecordset("tblEfdReceipts") has data before proceeding to update , below is the full code:

Set rs = db.OpenRecordset("tblEfdReceipts")
    If lngStatus > 0 Then
    ElseIf lngStatus < 0 Then
        ' Handle error.
        On Error Resume Next
    End If
        ' Process data.
  Set JSONS = JsonConverter.ParseJson(strData)
    Z = 2
  For Each item In JSONS
           With rs
         
            .AddNew
            rs![TPIN] = item("TPIN")
            rs![TaxpayerName] = item("TaxpayerName")
            rs![Address] = item("Address")
            rs![ESDTime] = item("ESDTime")
            rs![TerminalID] = item("TerminalID")
            rs![InvoiceCode] = item("InvoiceCode")
            rs![InvoiceNumber] = item("InvoiceCode")
            rs![FiscalCode] = item("FiscalCode")
            rs![TalkTime] = item("TalkTime")
            rs![Operator] = item("Operator")
            rs![Taxlabel] = item("TaxItems")("TaxLabel")
            rs![CategoryName] = item("TaxItems")("CategoryName")
            rs![Rate] = item("TaxItems")("Rate")
            rs![TaxAmount] = item("TaxItems")("TaxAmount")
            rs![VerificationUrl] = item("TaxItems")("VerificationUrl")
            rs![INVID] = Me.InvoiceID
            rs.Update
        End With
        Z = Z + 1
    Next
      
      rs.Close
      Set rs = Nothing
      Set db = Nothing
      Set JSONS = Nothing

I’m trying this code but I’m not sure of how do it correctly, the received data is never part of the live until checked.

Validation code require improvements

Set rs = Me.Recordset.Clone
If Me.Recordset.RecordCount = 0 then 'checks for number of records
   msgbox "There is no records" 
End if
