>Excel allows to hide a sheet. Then, we can click on any sheet and select Unhide to make that previous sheet visible again. What I need to do is password protect the unhide functionality. What would be the best practive to achieve that?
You can get some ideas from Googling [excel password protect single sheet].
Depending on your use case you might be able to have 2 different versions of the whole workbook: one with the hidden page either not accessible at all or not present, and the other with the page visible and accessible.
