If it was previously saved you can re-open it and start re-entering what you
lost.
If it was a new workbook, there is basically nothing to recover.
There are are third-party data recovery services out there which are pricey.
If you want to go that route, STOP using your computer immediately to enhance
your oppotunity of finding the file data before those clusters get
overwritten.
