Answer 1

you can use nested dictionaries

Sub test()

    With New Scripting.Dictionary
        Dim cel As Range
            For Each cel In Range("A1").CurrentRegion
                If Not .Exists(Split(cel.Value, ".")(1)) Then .Add Split(cel.Value, ".")(1), New Scripting.Dictionary
                .Item(Split(cel.Value, ".")(1)).Add cel.Value, 1
            Next
        
            Dim iK As Long
                For iK = 0 To .Count - 1
                    Range("C1").Offset(, iK).Resize(.Items(iK).Count).Value = Application.Transpose(.Items(iK).Keys)
                Next
    End With
    
End Sub

just add reference to "Microsoft Scripting Runtime" library
