Not every feature of Excel is active and available.
Some features have to be added by the user.
This provides a list of add-ins available to Excel. One of the available add-ins is the Analysis ToolPak. This is an add-in that deals with statistical functions, such as histogram, rank and percentile, and Fourier Analysis. With the Auto-save, you can establish when Excel will save your sheets automatically. After performing the add-in, you can find the Autosave under the Tools menu.
