Answer 1

It can be  done with "Script Component" transformation by making it as asynchronous component ((because
the number of output rows differs from the number of input row) .
To make the component as asynchronous ,we need to  set the "SynchronousInputId" property to None
 In an asynchronous script component you have to override the "Input0_ProcessInputRow"
method.
Example:
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
    Dim keyField As Integer = Row.KeyField 
    Dim itemList As String = Row.ListField 
    Dim delimiter As String = ","
    If Not (String.IsNullOrEmpty(itemList)) Then
        Dim inputListArray() As String = _ 
            itemList.Split(New String() {delimiter}, _ 
            StringSplitOptions.RemoveEmptyEntries)
        For Each item As String In inputListArray 
            With Output0Buffer 
                .AddRow() 
                .KeyField = keyField 
                .ListItem = item 
            End With 
        Next
    End If
End Sub
