Hi RY,
Thanks for posting in the community. We're happy to help you.
Regarding your query, please try the following formula, and then check if it meets your requirements or not. I assume you use the Excel desktop app. If not, please point it out and let us know.
Let's say you want the static date stamp to be in B2.
- Change the Excel settings.
Go to File> Options> Formulas, under "Calculation options", tick the option "Enable iterative calculation".
- Put the formula in B2. Select B2, set the cell format to "Date" and choose the related date format.
=IF(A2<>"",IF(B2<>"",B2,NOW()),"")
- Enter anything in A1.
We look forward to your response. Thanks for your cooperation.
Sincerely,
