The xar file extension is associated with Microsoft Excel, one of the most popular and powerful tool you can use to create format spreadsheets, graphs and much more.

The xar files are used since Microsoft Excel 2007 for autosaving purposes. Microsoft Excel 2007 and later 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.
