How to Fix Excel File Couldn’t Open in Protected View

Summary: This blog discusses about the Excel error ‘The file couldn’t open in Protected View’ and workarounds to fix the error. If you cannot access the Excel file data, using an Excel file repair tool can help you quickly restore the data to its original state.

Protected View is a feature in Microsoft Excel that opens a file in read-only mode while disabling the editing functions. An Excel file opens in Protected View if the file is from an unsafe location. For example, the file may be opened from an insecure Internet location or downloaded as an Outlook attachment from suspicious senders. In that case, your Excel application won’t let you open the file to protect it against malware or virus attacks.

However, the Protected View feature sometimes prevents an Excel file from opening even if it is from a safe location. Also, opening an Excel file may return an error message ‘file couldn’t open in protected view’.

You may be able to resolve the issue by closing all the open Excel files, closing the Excel application, and then re-opening the problematic file. But this process can take a significant amount of time as you need to close and re-open the Excel application and the file continuously.

How to Fix the Excel File Couldn’t Open in Protected View Error?

Here are some workarounds to fix the error:

Workaround 1 – Disable the Protected View Settings

Note: Before disabling the protected view settings, ensure you have a reliable antivirus software installed on your computer to safeguard files against malware or virus attacks.

• Open the Excel file throwing the error, go to File and click the Options tab.
• From the Options dialog box, go to Trust Center and click on Trust Center Settings.
• From the Trust Center Settings dialog box, select the Protected View tab.
• Uncheck the appropriate option under the Protected View section, and then click OK to apply the changes. For instance, uncheck the “Enable Protected View for Outlook attachments” option if the file is a downloaded Outlook attachment.

• Click OK again.

Now try opening the problematic Excel file. If it still doesn’t open, try the following workaround.

Workaround 2 – Repair the Office Installation

Sometimes, corruption in the Office installation may cause Excel to return the ‘file could not open in protected view’ error. So, try repairing your Office installation and check if it solves the problem.

• Open the Control Panel and click the Uninstall a program option under Programs.
• Click Uninstall a program under the Programs tab.
• Right-click the Microsoft Office program you have installed and click the Change button.
• Select the Repair option and click Continue.

Once the repair operation is complete, check if you can open the Excel file without any issue.

Workaround 3 – Install Latest MS Office Updates

Several Excel users have reported about experiencing issues (such as the Protected View issue) on opening an Office document like Excel, Word, or others – after upgrading Windows to a newer version. This problem may occur due to incompatibility between the Office app and the updated Windows version. You can try to fix the problem by upgrading the Office app, and here’s how:

• Click on the File tab in the Excel file that throws an error.
• Click the Account tab at the left-hand bottom of the screen.
• From Office Updates, expand Update Options, and then click Update Now.

After installing the updates, restart your PC and open the Excel file. If this doesn’t work, use the following workaround.

Workaround 4 – Convert the File and Rename It

Some Excel users resolved the ‘Protected view’ issue by renaming their Excel files. But before that, ensure that the file you are trying to open is saved with .xlsx format. If the file type is .xls, you need to convert it to .xlsx format and then rename it. Before converting the file, save a copy of the original file in the desired location.

If the file type is .xlsx, copy the problematic file. Next, open a blank Excel document and paste the copied file. The file will appear as an icon, double-click on it. If it opens without any error, save it with a different name. Hopefully, reaming the Excel file may help resolve the problem.
