You may find it helpful to sometime place the contents of a cell into the footer of a worksheet, and to have the footer updated every time the contents of the cell changed. The easiest way to do this is with a macro. The following is an example of a macro that will place the contents of cell A1 into the left side of the footer:

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
    ActiveSheet.PageSetup.LeftFooter = Range("A1").Text
End Sub

The macro is run every time Excel does its normal recalculation—meaning every time the contents of any cell changes or someone presses F9. If you want the contents to be in a different part of the footer, you can change LeftFooter to CenterFooter, or RightFooter.

To apply any formatting to the footer other than the default you will need to add special formatting codes, and you can also use special data codes that Excel recognizes for headers and footers. Both the special formatting and special data codes are quite lengthy and have been covered in other issues of ExcelTips.

If you are working with a very large worksheet, then changing the footer every time Excel recalculates may unnecessarily slow down your computer. After all, the footer remains invisible to the user until such time as the worksheet is actually printed. In this case, you simply need to rename the above macro to some other name that you would then manually execute as the last step before printing a worksheet.
