Unlocking sheets in Excel can be a lifesaver when you're collaborating with others or working on complex spreadsheets where access control is key. If you've ever found yourself locked out of editing or viewing a specific part of a workbook, fear not—this guide will walk you through five easy methods to regain access and make those locked sheets accessible again. Let’s dive in!
1. Using the Unprotect Sheet Feature
Excel provides a built-in feature for unprotecting sheets which is the easiest way to unlock your document:
- Open the Excel workbook containing the locked sheet.
- Select the protected sheet tab at the bottom of the workbook.
- Click on the “Review” tab on the Excel ribbon.
- Find and click “Unprotect Sheet”.
- If the sheet was protected with a password, enter the password and click OK.

⚠️ Note: If you're the one who protected the sheet and forgot the password, there's no built-in way to recover it within Excel. You might have to proceed to other methods.
2. VBA Macro to Unprotect Sheets
Visual Basic for Applications (VBA) can bypass sheet protection without passwords in some scenarios:
- Open your Excel workbook.
- Press Alt + F11 to open the VBA editor.
- Go to Insert > Module.
- Copy and paste the following code:
Sub UnprotectAllSheets()
Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
ws.Unprotect
Next ws
End Sub
- Run the macro by placing the cursor inside the code and pressing F5.

4. Hex Editor Method
Using a hex editor can manipulate the Excel file structure directly:
- Close Excel completely.
- Make a backup of your Excel file for safety.
- Open the file in a hex editor.
- Search for “DPB=” which represents the workbook protection information.
- Change the data following “DPB=” to remove the protection code.
- Save the file and open it in Excel.

- Go to File > Info > Protect Workbook > Unprotect Workbook.
- If prompted, enter the password if the workbook is password protected.
- Now, you can remove protection from individual sheets.

From using built-in tools like Unprotect Sheet to more technical approaches like hex editing or using VBA macros, the key is understanding your file’s protection level and choosing the right method. Each technique has its place, from quick fixes to more intricate solutions when simple methods fail. Keep in mind the importance of using these techniques ethically and with caution to avoid any potential file corruption or security issues.
