S2 Recovery Tools for Microsoft Excel 4.0.1
Microsoft recommends several methods for recovering Excel data from corrupt spreadsheets.
Excel Recovery makes it easy to follow these recommended routines by just pressing buttons.
The application also adds five methods of its own for recovery. Additionally it has its own native previous file version recovery tool which works in any version of Vista, Windows 7 and maybe Windows 8. Also the program has a preloaded search interface for finding temporary and deleted versions of your corrupt file.
For completeness sake the program has shortcuts to 2 major commercial solution providers for corrupt Excel files including providing the coupon 'S2SERVICES' for using Recoveronix' online corrupt file recovery service for free until Nov 1, 2013, a $39 value.
