Excel workbooks that are embedded are still “live”, so whenever you update the source workbook, the embedded viewer will display that updated content as well. However, modifications that people make in the embedded viewer are always personal and temporary (only for that browser session), and so don’t affect the underlying workbook itself. This allows people consuming your content to explore it themselves without changing it for everyone.
