How do I ignore the first row in an Excel macro that deletes all rows based on a criteria?

Question

This macro is designed to compare the data in column C and D and if C does not match D in a certain row, it deletes the entire tow. The problem is that it deletes the header

Answer 1

you can avoid loops:

Sub deleteNonMatchingRows()
    With Range("C2", Cells(Rows.Count, "C").End(xlUp)) ' reference column C cells from row 2 doen to last not empty one
        With .Offset(, .Parent.UsedRange.Columns.Count) ' reference referenced range offset by active sheet used range columnns (to be sure you'r not overwriting already filled cells)
            .FormulaR1C1 = "=IF(RC3<>RC4,1,"""")" ' have referenced cells show a "1" if corresponding cells in column C and D match
            .SpecialCells(xlCellTypeFormulas, xlNumbers).EntireRow.Delete ' delete all rows whose referenced column formula result is a number
            .ClearContents ' clear referenced range
        End With
    End With
End Sub
