You can't directly "open" an Excel file in Protected View. Protected View is a security feature that opens a file in a restricted mode, preventing potential threats from malicious code. This happens automatically when Excel identifies a file as potentially unsafe.
Here's how to understand Protected View:
- It's a security measure: Protected View helps safeguard your computer by limiting what an Excel file can do. This is especially important when opening files from unknown sources or those downloaded from the internet.
- It limits functionality: When a file is in Protected View, you can't edit, save, or print it. You can only view the file's contents.
- It's temporary: You can enable editing by clicking the "Enable Editing" button in the yellow warning bar at the top of the window.
To open an Excel file in Protected View:
- Download or open the file: This could be from an email attachment, a website, or a shared network drive.
- Excel will automatically open the file in Protected View: You'll see a yellow warning bar at the top of the window.
- Review the warning message: This message will tell you why the file is in Protected View.
- Click "Enable Editing" if you trust the file: If you're sure the file is safe, you can click the "Enable Editing" button to unlock the file for full functionality.
- Keep the file in Protected View if you're unsure: If you're not sure about the file's origin or safety, it's best to keep it in Protected View to avoid potential risks.
Remember: It's always good practice to be cautious when opening files from unfamiliar sources.
