Select File > Open and click 'Recover Unsaved Workbooks' near the bottom of the window.

@HansVogelaar   I don't see that option under File in Excel.  I closed a file and accidentally hit "don't save". Hoping there is a way to undo that as I blew off hours of work.  Ugh!

Are you using the desktop version of Excel for Windows? Or for Mac? Or the online (browser) version?
