Solutions to open Excel Read Only Documents

'Excel cannot open read-only documents' is an error message that usually appears when you try to open an Excel (XLS or XLSX) file downloaded from the Internet, email, or the network server. It may also appear when you try to open an encrypted or password-protected Excel document. In such a case, MS Excel prevents the user from making any changes to the document.

Reasons behind the “Excel cannot access 'xxx.xls.' The Document may be read-only or encrypted” Error

There could be several reasons that may cause the error. Some of them are as follows:

• Corrupt or damaged Excel workbook
• Incompatible or unsupported add-in
• Antivirus or malware software conflict
• Read-Only Excel file
• The file is encrypted
• File or drive read/write permissions issues
• Protected Excel workbook
• Damaged or missing MS Office (MS Excel) program files

Solutions to Open and Edit Read-Only Excel Documents

Below are a few solutions that can help you fix the 'Excel cannot access 'xxx.xls.' The Document may be read-only or encrypted' error and allow you to open and edit Excel documents.

• Remove Read-only Attribute from Excel File Properties

The 'Excel cannot open read-only documents' error message may appear when the Excel file property is set to read-only. To check if this is the case, follow these steps:

• Right-click on the particular Excel (xls/xlsx) document and select 'Properties'.
  • Uncheck the 'Read-only' attribute and then click the 'OK' button.

Now try to open the Excel document and check if the problem is fixed.

• Adjust Antivirus Settings

A few antivirus programs block Excel files and other Office documents by opening those in 'read-only' mode. In such cases, try adjusting the antivirus settings to open the Excel files normally. This will allow you to edit, modify, and save the Excel workbook without encountering the “Excel cannot access 'xxx.xls.' The Document may be a read-only or encrypted” error message.

• Disable Protected-View

The error may appear when you try to open an Excel file received as email attachments or downloaded from unsafe source. The file may potentially contain viruses, worms, or other types of malware that could damage the system or the server.

To safeguard the system, MS Excel opens such files in Protected View. It may also open an Excel workbook in Protected Mode when it detects a problem with the file. This security feature allows you to read or view Excel files and reduces the risks to the computer system or PC.

However, you can click File > Info and then click 'Edit Anyway' to access and edit file content. You may also disable the Protected View setting via File > Options > Trust Center > Trust Center Settings…> Protected View. However, we do not recommend this.

• Renew/Activate Microsoft Office

If MS Office is in a deactivated state or its subscription has expired, the Office documents, including the Excel, could be in 'read-only reduced functionality mode.'

In such a scenario, activate Microsoft Office or renew the Office subscription. Then open the Excel workbook and check if the problem of 'Excel cannot open read-only documents' is resolved.

• Check if OneDrive Storage is Full

If Excel files are saved on OneDrive with low or no storage space, you may encounter such issues with your files.

To know the amount of free space on OneDrive, follow these steps:

• On your PC, open Settings and navigate to OneDrive.
  • Click 'Sync Settings > File Storage' to see available space.

You may also visit onedrive.live.com, sign in to the account, and then check the available space. If there's no space available or the drive is full, empty the storage space and see if the problem is resolved.

• Check and Update MS Office and Windows

Microsoft releases updates to fix known errors. Thus, it is critical to update both Windows and MS Office to the latest release and avoid issues, such as 'Excel cannot access 'xxx.xls.' The Document may be read-only or encrypted.'

• Repair MS Office (MS Excel)

The error 'Excel cannot open read-only documents' may appear due to a problem with your MS Office (MS Excel) program. You can repair the MS Office program to resolve such errors. The steps are as follows:

• Open Control Panel and click Uninstall a Program link under Programs.
• Choose Microsoft Office from the list and click the Change button.

• Select Quick Repair and then click Repair to fix problems with MS Office and MS Excel. It will also restore any missing or damaged program files.

After the Repair, open the Excel workbook and check if the error is resolved.

• Check Permissions

The error message may also appear if you access an Excel workbook from a network or shared drive due to lack of write permission. Make sure you have read and write permissions assigned for the particular network drive. Alternatively, you can copy the file from the network drive and save it in your local folder to access and edit it without encountering this error message.
