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 saved. (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.xlsx") Cells(1, 1) = f.DateLastModified End Sub
To use the macro, just replace the D:\MyFolder\MyFile.xlsx 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:
Figure 1. The Editing tab of the Share Workbook dialog box.
Figure 2. The Advanced tab of the Share Workbook dialog box.
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.
