How to protect an Excel sheet with VBA?

Protecting an Excel sheet using VBA involves using a few lines of code to password-protect the sheet, which limits what users can do within it. Here’s a step-by-step guide to achieve this:

Sub ProtectSheet()
    Dim ws As Worksheet
    Set ws = ThisWorkbook.Sheets("Sheet1") ' Replace "Sheet1" with the name of your sheet
    ws.Protect Password:="yourpassword", AllowSorting:=True, AllowFiltering:=True
End Sub

Sub UnprotectSheet()
    Dim ws As Worksheet
    Set ws = ThisWorkbook.Sheets("Sheet1") ' Replace "Sheet1" with the name of your sheet
    ws.Unprotect Password:="yourpassword"
End Sub

Open VBA Editor:

Press `ALT` + `F11` to open the Visual Basic for Applications (VBA) editor.

Insert a Module:

In the VBA editor, go to `Insert` > `Module` to create a new module where you can write your VBA code.

Write the VBA Code:

In the module window, you can write a macro that protects the desired worksheet. Here’s an example code snippet:
Replace `”Sheet1″` with the actual name of the sheet you want to protect.
Replace `”yourpassword”` with the password you’d like to use.
The `AllowSorting` and `AllowFiltering` parameters are optional and can be modified based on the actions you want to permit. Other options like `AllowInsertingRows`, `AllowDeletingRows`, etc., can be included as needed.

Run the Macro:

Close the VBA editor to return to Excel.
Press `ALT` + `F8`, select `ProtectSheet`, and click `Run`.

Test the Sheet Protection:

Try to modify the sheet to ensure the protection is active. You should be prompted to enter a password for unauthorized actions like editing protected cells.

Unprotecting the Sheet (Optional):

If you need to unprotect the sheet, you can use another macro:

Remember to replace the names and passwords as per your requirement.

By following these steps, you should be able to protect your Excel sheet with a password using VBA. Make sure you keep the password secure, as forgetting it may make it difficult to access the sheet content.
