Excel文件的內容消失

If the Microsoft Office or Office family program you are using is not responding, recover the program. On the Microsoft Windows Start menu, point to Programs, point to Microsoft Office Tools, and then click Microsoft Office Application Recovery.
In the Application list, click the program or document that is not responding.
Do one of the following:
To attempt to recover the files you were working on, click Recover Application or Restart Application.
If you just want to close the program, and lose recent changes to the files, click End Application.
The error that caused the problem can be reported to Microsoft for use in improving future versions of the program. Click Report problem or Don't report problem.
Open Excel.
Review the files listed in the Document Recovery task pane (task pane: A window within an Office application that provides commonly used commands. Its location and small size allow you to use these commands while still working on your files.), and decide which to keep.
If a file has [Recovered] in the title it is usually a file that contains more recent changes than a file with [Original] in the title.
If you want to view what repairs were made to a file, point to the file in the Document Recovery task pane, click the arrow next to the file's name, and then click Show Repairs.
If you want to review the versions that were recovered, open all of the versions and save the best one.

To save the file, click Save As, and then enter a name for the file. By default, the file is saved in the same folder as the original file. If you use the same name as the original file, the original is overwritten.

When you see a message asking whether you want to replace the existing file (with the changes you made up to the last time you saved the file), click Yes.
When you have opened or saved all of the files you want to keep, click Close in the Document Recovery task pane.
