Method 2: Excel’s Built-In Password Feature

Method 3: Using VBA Code
For those familiar with programming, VBA (Visual Basic for Applications) in Excel can add passwords to multiple files at once. This method, however, requires technical knowledge.
Sample VBA Code:
Sub ProtectWorkbook() Dim ws As Worksheet For Each ws In ThisWorkbook.Sheets ws.Protect Password:="YourPassword" Next ws End Sub
