Deleting Empty Rows:-

To delete empty rows in a selected range we can use the following macro. The macro here uses the For Next Loop. First the macro counts the rows in a selected range to determine the when the macro should stop. The For Next statement acts as a counter.
Sub DelEmptyRow()
Rng = Selection.Rows.Count
ActiveCell.Offset(0, 0).Select
Application.ScreenUpdating = False
For i = 1 To Rng
If ActiveCell.Value = "" Then    'You can replace "" with 0 to delete rows with 'the value zero
Selection.EntireRow.Delete
Else
ActiveCell.Offset(1, 0).Select
End If
Next i
Application.ScreenUpdating = True
End Sub
