Microsoft Excel Backup
Unknownspreadsheet
Microsoft Excel has a built-in AutoRecover feature that has replaced the AutoSave add-in that exists in versions of Excel that are earlier than Microsoft Excel 2002. The AutoRecover feature saves copies of all open Excel files at a user-definable fixed interval. The files can be recovered if Excel closes unexpectedly, for example, during a power failure.
