Q. Help! I have been working on a very important Excel file for a client, and suddenly my computer locked up and says, “Excel is not responding.” Is there anything I can do so that I don’t lose all of my work?

A. We have all been there. It’s a terrible feeling when you have put so much work into your file and suddenly you are forced to close it without saving, or the application closes on its own. The best approach to avoid this scenario is to use autosave, but that doesn’t solve the problem posed in the question. The good news is that most of the time, your file can be recovered. You just have to know where to find it.

Let’s consider two scenarios when you may want to recover your work: (1) You are working on a new file and have never saved the file at all; or (2) your previously saved file closes before you can save the changes made since your last save. Either way, your files may be recoverable but would be recovered in different ways. You can access a video showing the following steps at the bottom of the page.

For the first scenario described above, the way to recover your never-before-saved file is to, first, open Microsoft Excel. Then go to the File tab on your Ribbon and click Open. Click Recent and then scroll to the bottom of the page and click Recover Unsaved Workbooks.

Another scenario when you may need to recover a file is when your previously saved file closes before you can save the changes made since your last save. To recover the file, open Excel once your computer is working properly. A Document Recovery pane should appear with all unsaved Excel files listed. Choose the file that you want to recover.
