两种方法清除Excel保护密码

两种方法清除Excel保护密码,第1张


一、利用VBA脚本直接清除

Excel,打开脚本编辑器(Alt+F11)或者如图,右键sheet名称

输入代码并运行,即可清除密码保护:

Sub DeletePW()
    ActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=True
    ActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=True
    ActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=True
    ActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=True
    ActiveSheet.Unprotect
End Sub


二、用python代码批量处理多个Excel文件 

注意:这种方法前提是得知道密码。


直接上代码:

            filepath = os.path.join(path, file)
            if not os.path.isfile(filepath):
                continue
            print(filepath)
            xlApp.Visible = False
            xlApp.DisplayAlerts = False
            wb = xlApp.Workbooks.Open(filepath)
            try:
                # print(password)
                wb.Unprotect(password)
                wb.Checkcompatibility = False
                sht = wb.Worksheets('Sheet1')
                sht.Unprotect(password)
            except Exception as err:
                print('清除 %s 的保护密码出错:%s' % (file, err))


            wb.Save()
            wb.Close(SaveChanges=True)

    finally:
        if hasattr(xlApp, 'Quit'):
            xlApp.Quit()



path=r'E:\数据21院校专业计划'
password=r'135246'
removePassword(path,password)
