    第一步,先找到一個帶有有工作表保護密碼的Excel工作表,然後把字尾名稱改為.rar。;第二步,用壓縮檔案開啟,然後找壓縮的對應路徑。;第三步,把從壓縮檔案裡面找到的.xml檔案,然後拖拽出來,進行修改。;第四步,把保護程式碼刪除來撤消工作表保護,找到這個.xml檔案用記事本開啟,然後搜尋【protection】,把從<sheetprotection.........="0"/>的程式碼,全部刪除掉,如圖所示。;第五步,然後再把剛剛修改後的.xml檔案,選擇拖拽到壓縮的工作表中替換掉。;第六步,再把檔名稱字尾改為.xlsx,開啟Excel表格,密碼保護就可以取消了。;第七步,撤消保護工作表後,還可以在【審閱】選項下對工作表重新進行進行保護和撤消保護工作表操作,如圖所示。
