Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Noting When a Workbook was Changed.
In an environment where multiple people work on the same workbook, you may want a way to keep track of when people last changed a workbook. There are a couple of ways you can approach this task. One is to simply figure out when a workbook was last saved. This approach works well if you assume that any changes to the workbook are always changed. (Unsaved changes, of course, are not really a lasting change at all.) The following macro returns the date that a workbook was saved and stores that date in cell A1:
Sub DateLastModified() Dim fs, f Set fs = CreateObject("Scripting.FileSystemObject") Set f = fs.GetFile("D:\MyFolder\MyFile.xls") Cells(1, 1) = f.DateLastModified End Sub
To use the macro, just replace the D:\MyFolder\MyFile.xls file specification with whatever is appropriate for you.
If you want a history sheet of who did what with your workbook, then a different approach is necessary. Perhaps the best solution is to try Excel's sharing feature, which can be configured to keep a history log for a workbook. Follow these steps:
As changes are made to the workbook, Excel tracks those changes (along with who made them) and puts them in a separate worksheet so you can review them later.
