Excel sheet protection is a security feature that prevents unauthorized editing of worksheet content. When a sheet is protected, users cannot:

• Edit cells, formulas, or formatting
• Insert or delete rows and columns
• Modify pivot tables or charts
• Change worksheet structure

3. Click UNLOCK button

Method 2: VBA Macro Code

Use VBA code to programmatically remove sheet protection. This free method works well for single or multiple protected sheets.

VBA Code:

Sub UnprotectAllSheets()

    Dim pwd As String

    pwd = "defaultpassword"

    For Each ws In ActiveWorkbook.Worksheets
        On Error Resume Next
        ws.Unprotect Password:=pwd
        If Err.Number = 0 Then
            MsgBox ws.Name & " unprotected!"
        Else
            ws.Unprotect
            MsgBox ws.Name & " unprotected without password!"

Sometimes saving the file in a different format can remove protection:

1. Open protected Excel file
2. File → Save As
3. Save as .xlsb (Binary Workbook)
4. Close and reopen file
5. Try to unprotect sheet (may work without password)
6. Save back as .xlsx if successful

Method 5: Google Sheets Bypass

Upload to Google Sheets to potentially bypass protection:
