一、利用VBA腳本直接清除
打Excel，打開腳本編輯器（Alt+F11）或者如圖，右鍵sheet名稱
輸入代碼并運行，即可清除密碼保護：
Sub DeletePW()ActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=TrueActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=TrueActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=TrueActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=TrueActiveSheet.Unprotect
End Sub
二、用python代碼批量處理多個Excel文件?
注意：這種方法前提是得知道密碼。
直接上代碼：
