Find first non formatted cell in range

TMS,
Sorry I don't really understand the code, How can I incorporate this so that my code then executes from the selected cell down?

Selection.TextToColumns Destination:=Range("R1"), DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, _
        Semicolon:=False, Comma:=False, Space:=False, Other:=False, FieldInfo _
        :=Array(1, 4), TrailingMinusNumbers:=True
