You can only do this through VBA. Try:

Sub Workbook_Open()
Sheets("Sheet1").Range("A1"). _
Value = Format(Now, "mm/dd/yy")
End Sub

---
Press ALT+F11, click on the module called "This Workbook",
and insert the code. Press ALT+Q and save the workbook.

I have a template that automatically populates the date
field with the
current date when opened, using today(). Users then Save
As to have an
archive copy of their spreadsheet. However, when they go
back to access
their saved sheet, the date changes from the created date
to the current
date. How do I stop this in Excel?

I know that Word lets you do this by changing the code
from {DATE} to
{CREATEDATE}, but I can't find a similar setting in
Excel.

Please help and thank you!
