[Fixed]: Excel File couldn’t Open in Protected View

<?xml encoding="utf-8" ?><?xml encoding="utf-8" ?>

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 can get this error due to various reasons and factors. Below, we will see how to resolve this Excel error.

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.

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.

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.
