Password Protect an Excel Worksheet to Restrict Viewing

There are many reasons why you would want to restrict access to a worksheet in Excel. You may have confidential information or sensitive data that you want to keep private. Instead of locking down the entire workbook, it is more practical to restrict access to a specific sheet tab.

How to Protect an Excel Worksheet to Keep It from Being Viewed

To lock down an Excel sheet, the best approach is to hide the sheet tab and enable Protect Workbook.

Hiding an Excel sheet is an effective way to prevent prying eyes from seeing it. Most users won’t even know that the hidden worksheet exists, so they are less likely to make changes to your data.

The Protect Workbook feature ensures that even if users discover the hidden Excel sheet, they won’t be able to unhide it. Once the structure of your workbook is password protected, it becomes impossible to add, remove, or unhide worksheets.

Let’s take a closer look at this two-step process.

How to Hide an Excel Sheet from Prying Eyes

To hide an Excel sheet that contains sensitive data, follow these steps:

  1. Right-click on the sheet tab.
  2. Click on Hide in the shortcut menu.

It is important to note that hiding an Excel sheet alone is not sufficient. You must protect the workbook structure to prevent curious users from unhiding the worksheet and editing your data without permission.

To unhide an Excel sheet, follow these steps:

  1. Right-click on a visible worksheet tab.
  2. Click on Unhide in the shortcut menu to open the Unhide dialog box.
  3. Select one or more worksheets from the list.
  4. Click OK.

How to Password Protect the Workbook Structure

After hiding an Excel sheet, you need to enable password protection to lock down the structure of your workbook. Here’s how:

  1. Click on Protect Workbook in the Review > Protect group.
  2. The Protect Structure and Windows dialog box will appear.
  3. Enter a password and click OK.
  4. The Confirm Password dialog box will appear.
  5. Re-enter the password and click OK.

The Protect Structure and Windows dialog box

Once workbook protection is enabled, the Hide/Unhide commands will no longer be available. It is worth mentioning that you don’t necessarily have to supply a password in the Protect Structure and Windows dialog box. However, if you don’t, another user could simply disable Protect Workbook, right-click an existing sheet tab, and unhide any sheets containing confidential or sensitive data.

To disable workbook protection, click on Protect Workbook again, enter your password, and click OK.
