Is there a way to keep website visitors from editing cells?

I know that any changes to cells are not saved... that's good. However, I don't want my visitors to even be able to click and edit the cells in a spreadsheet at all. Right now, if I click on a cell, I can type whatever in it... then the only way to see the original data is to refresh the webpage. Is there a way so that none of the cells are clickable? I've locked and hid the formulas but that does nothing for keeping this truly unwriteable.

Thanks.
