Sometimes, Excel documents created on older computers or versions of Excel become unstable on newer versions; similarly, Excel documents can be saved in many different file formats. By changing the Excel file format to "xlsx" (or "xls" for older programs), you can fix this problem.
Click the Windows logo in the bottom-left corner of the screen.
Click the folder-shaped icon in the lower-left side of the Start window.
It's at the top of the File Explorer window. A toolbar will appear below this tab.
This option is in the "Show/hide" section of the toolbar. Doing so will allow you to see the file type extensions at the end of files, including your Excel document.
Go to the location of the Excel document that you want to recover, then click the document to select it.
It's a tab in the upper-left side of the File Explorer window. This will prompt a toolbar to appear.
This option is in the "Organize" section of the toolbar. Clicking Rename will cause the Excel file's name to become highlighted.

Change the file type. Replace whatever comes after the period at the end of the file name with xlsx and then press ↵ Enter.
- For example, if the document was named "Spreadsheet1.docx", you would change it to "Spreadsheet1.xlsx".
- If the file extension already is "xlsx", try using "xls" or "html".
This will confirm your changes and change the file extension.
11
Try opening the file. Double-click the file to open it. If the file opens in Excel (or, if you selected "html" as the extension, a web browser), your file has successfully been recovered.
- If you chose the "html" extension, you can convert the webpage into an Excel document by dragging the html file onto the Excel icon and then saving the file that opens as a new "xlsx" file.
- If the file still won't open, proceed to the next Windows method.

Like most Microsoft Office products, Excel will automatically save recovery versions of files, meaning that you may be able to restore a partial version of your corrupted Excel document. However, Excel doesn't always save these files in time, and you most likely won't be able to recover the whole document in this way.
Click the Windows logo in the bottom-left corner of the screen.
This will search your computer for the "This PC" program.
It's the computer monitor-shaped icon at the top of the Start window. Doing so opens the This PC window.

Question
I cannot open the file with my Excel file, but I can open it in another computer. Why?
Community Answer
It's likely that the other computer has either an older or newer version of Excel, and your document is not compatible with the version you have on your computer.

Question
How do I recover a deleted excel file in Windows 7?
Community Answer
y\You can use the same method. However, to change the file extension you will need to use CMD and run a command like this (make sure you are in the right directory): rename (corrupted excel file, add its file extension at the end) (corrupted excel filename, do NOT add the file extension at the end).(xls, xlsx).

You may be able to open an otherwise corrupted Excel file by placing your computer in safe mode. If so, a file error or a virus is most likely the reason for your document failing to open.
