What should I do if I forget my password to revoke worksheet protection?

Everyone who does data analysis knows that the correctness of the original data is very important. Often, a large deviation in the results will occur due to a data error.

Therefore, after the original data is entered and proofread in the worksheet, in order to prevent misoperation or random copying by others, the data will be protected.

But as the pace of modern life accelerates, and passwords are used in too many places, forgetting passwords often happens. Don’t you feel depressed when you can no longer modify a worksheet you worked so hard on because you forgot your password?

What should we do at this time? Do it again? In fact, it doesn’t have to be so troublesome. Below I will share with you two commonly used methods for clearing worksheet protection passwords.

Use VBA to clear

1. Click "Development Tools" in the menu bar, select Record Macro, and record a macro named "Clear Worksheet Protection Password" file (you can name the macro file according to your own habits).

2. Click "Development Tools" in the menu bar again, select "Macro" to open the macro dialog box, select the newly created macro file in "Macro Name", and then Click "Edit" to open the macro (VBA) editing window.

3. Select "VBAProject PERSONAL,XLSB" → "Module" → "Module 2" on the left side of the macro (VBA) editing window, and change the After deleting the original content in the code window, copy and paste the following code into the code window and save it.

4. Click "Development Tools" in the menu bar again, select "Macro" to open the macro dialog box, select the newly created macro file in "Macro Name", and then Click "Execute" or "Single Step", and the worksheet protection password will be cleared after the program is completed. (Tip: There is a lag when running the program. If the computer configuration is low, choose single-step execution. The effect is the same)

The VBA code is as follows:

Public Sub 工作表保护密码破解()
Const HUANHANG As String = vbNewLine & vbNewLine
Const MINGCHEN As String = "清除工作表保护密码"
Const JINGGAO As String = "该工作簿中的工作表密码保护已全部清除!!" & HUANHANG & "请记得另保存" _
& HUANHANG & "注意：不要用在不当地方，要尊重他人的劳动成果！"
Const TISHI1 As String = "该文件工作表中没有加密"
Const TISHI2 As String = "该文件工作表中没有加密2"
Const KSPJ As String = "解密需花费一定时间,请耐心等候!" & HUANHANG & "按确定开始清除!"
Const FXMM1 As String = "密码重新组合为:" & HUANHANG & "$$" & HUANHANG & _
"如果该文件工作表有不同密码,将搜索下一组密码并修改清除"
Const FXMM2 As String = "密码重新组合为:" & HUANHANG & "$$" & HUANHANG & _
"如果该文件工作表有不同密码,将搜索下一组密码并解除"
Const MSGONLYONE As String = "确保为唯一的?"
