Observed behavior

Solution 1Recommended

Manage Protection and Unlocked Regions in Excel for the Web

Use this solution to identify and remove intentionally unlocked cell ranges using the web version of Excel.

In Excel for the Web, the traditional Protection tab in the cell-format dialog is replaced by a dedicated Manage Protection pane. Editable cells on a protected sheet are typically caused by ranges being added to the 'Unlocked Regions' list.

1
Open the Review Tab

Open your workbook in Excel for the Web and click on the 'Review' tab in the top ribbon.

2
Access Manage Protection

Click on 'Protection' and select 'Manage Protection' from the dropdown menu to open the side pane.

3
Review Unlocked Regions

Look under the 'Unlocked Regions' section. This list displays the ranges that are allowed to remain editable when the worksheet is protected.

4
Remove Unwanted Unlocked Regions

If you want these cells to be locked, remove the ranges from the Unlocked Regions list. The cells will now follow the standard locked behavior of the protected worksheet.

Missing Protection Options: If the Manage Protection option is completely unavailable in the web version, the workbook might have unsupported legacy protection settings. You will need to manage the protection using the desktop version.

Frequently Asked Questions

Why is the Protection tab missing in my Format Cells dialog?

In Excel for the Web, the traditional Protection tab inside the Format Cells dialog is not supported in the same way as the desktop version. Instead, you must use the 'Manage Protection' pane located under the Review tab to configure which ranges are locked or unlocked.

How do I ensure all cells are locked before protecting a worksheet?

Select the entire worksheet by clicking the triangle in the top-left corner (or pressing Ctrl+A). Right-click any cell, select 'Format Cells', go to the Protection tab, ensure the 'Locked' box is checked, and click 'OK'. Then, proceed to protect the sheet from the Review tab.

Can I allow specific users to edit protected cells with a password?

Yes, in the desktop version of Excel, you can use the 'Allow Edit Ranges' feature under the Review tab. This lets you define specific ranges and assign unique passwords to them, so only users who know that specific password can edit those cells while the rest of the sheet remains protected.
