Excel Repair

Khalid805 You can try opening the file with "Open and repair" Option. The said option will appear when Excel is already open you are specifying the file to be opened there you find the above option which is very much helpful in recovering large dataset and important text, data from a corrupt dataset.

Mostly all your formatting and formals will be lost and only plain data and text will be recovered in most cases i have seen. You may also try sending the file to the community and let us give a try for the same from our end. 

Hope it helps.
