Many people use Excel as a simple database manager, entering information in different rows of a worksheet. As you are working with your data tables, you may come across a need to reverse the order of the rows in the table. Thus, if you have a table with ten rows, the rows would go from ten to one instead of one to ten.
There is no intrinsic function in Excel that allows you to flip data in this manner. However, you can use the sorting capabilities of Excel to accomplish the same thing by following these general steps:
Figure 1. The Sort dialog box.
If you have to do a lot of data flipping on a daily basis, using the above steps can get rather tiring. In this case, you may want to create a macro to do the job for you. The following macro, FlipRows, will do the trick:
Sub FlipRows() Dim vTop As Variant Dim vEnd As Variant Dim iStart As Integer Dim iEnd As Integer Application.ScreenUpdating = False iStart = 1 iEnd = Selection.Rows.Count Do While iStart < iEnd vTop = Selection.Rows(iStart) vEnd = Selection.Rows(iEnd) Selection.Rows(iEnd) = vTop Selection.Rows(iStart) = vEnd iStart = iStart + 1 iEnd = iEnd - 1 Loop Application.ScreenUpdating = True End Sub
In order to use this macro, all you need to do is select the rows you want flipped and run it. The macro will not change your data, other than flipping the rows. In other words, it will not add any columns of information.
An interesting feature of this approach is that you can quickly adapt it to flipping columns of data. All you need to do is change all occurrences of the word "Rows" to "Columns." Thus, the following becomes the new macro:
Sub FlipColumns() Dim vTop As Variant Dim vEnd As Variant Dim iStart As Integer Dim iEnd As Integer Application.ScreenUpdating = False iStart = 1 iEnd = Selection.Columns.Count Do While iStart < iEnd vTop = Selection.Columns(iStart) vEnd = Selection.Columns(iEnd) Selection.Columns(iEnd) = vTop Selection.Columns(iStart) = vEnd iStart = iStart + 1 iEnd = iEnd - 1 Loop Application.ScreenUpdating = True End Sub
Again, simply select the columns you want to flip and then run the macro.
