I have approx. 50 workbooks in Microsoft Excel – OfficeXP which are Password protected and the password is same for all workbooks. Suddenly, I am unable to any workbook as it says password incorrect. I checked everything like Caps lock etc. but unable to open any of the workbook. All the files contain very important Data and I don’t have any back-up of these files. Could you advise what is the reason and how to acess the data.
