Thank you for using my name is ***** ***** I am going to answer your question today:
Microsoft Excel provides automatic recovery for a corrupted file by attempting to reopen and simultaneously repair the file. Excel identifies what it changed while repairing the file. If the repair fails, Excel again tries to open the file but instead of attempting a repair, Excel extracts cell values and formulas leaving only the data. Under some circumstances, however, Excel won't automatically go into recovery mode, so users may find it necessary to recover file data manually.
To manually repair a file
1) On the File menu, click Open.
2) In the Open dialog box, select the file you want to open, and click the arrow next to the Open button.
3) Click Open and Repair, and then choose which method you want to use to recover your workbook.
If the above steps don't work, then the data is lost. Below is information on saving frequently as well as turning on auto save in Excel so if this ever happens again you will have backups to restore to.
Saving a backup copy of your file
As a preventative measure, you may want to save your file often and create a backup copy every time you save. In the Save As dialog box (File menu, Save As command), click Tools, click General Options, and then select the Always create backup check box. This way, you'll have access to a good copy of the file, should the original be accidentally deleted or become corrupted.
You can also make sure that Excel automatically creates a recovery file at specific intervals. In the Options dialog box (Tools menu, Options command), on the Save tab, select the Save AutoRecover info every check box, and then specify a number of minutes. In the AutoRecover save location box, specify the location where you want to save the recovery file. Make sure that the Disable AutoRecover check box (under Workbook options) is not selected.
