You can apply the following array formula to get the position of the first lowercase from the text strings, please do as this:

Enter this formula: =MATCH(1,IF(ABS(CODE(MID(A2,ROW(INDIRECT("1:"&LEN(A2))),1))-109.5)<=12.5,1),0) into a blank cell where you want to get the result, and then press Ctrl + Shift +Enter keys together to get the first result, then drag the fill handle down to the cells you want to apply this formula, see screenshot:

    L = Len(v)
    For j = 1 To L
        If Mid(v, j, 1) Like "[a-z]" Then
            Getlower = j
            Exit Function
