① excel表格忘記密碼打不開怎麼辦
Excel有兩種設置密碼的方式：
一，給整個工作簿設置密碼
② excel密碼忘了怎麼辦
1、新建一個EXCEL文件「BOOK1」，
在工具欄空白位置，任意右擊，選擇Visual Basic項，
彈出Visual Basic工具欄：
2、在Visual Basic工具欄中，點擊「錄制」按鈕，
彈出「錄制新宏」對話框，選擇「個人宏工作簿」：
3、選擇「個人宏工作簿」後按確定，
彈出如下「暫停」按鈕，點擊停止：
4、在Visual Basic工具欄中，點擊「編輯」按鈕：
5、點擊「編輯」按鈕後，彈出如下圖的編輯界面：
找到「VBAProject（PERSONAL.XLS）－模塊－模塊1（也可能是模塊N-其他數字）」
雙擊模塊1－將右邊代碼內容清空
6、復制「工作保護密碼破解」代碼到右邊框中，點保存，然後關閉「BOOK1」
7、運行需要解密的「EXCEL文件」，在Visual Basic工具欄中，點擊「運行」按鈕
8、點擊「運行」按鈕後，彈出「宏」對話框，
點擊運行「PERSONAL.XLS!工作保護密碼破解」這個宏
9、運行「PERSONAL.XLS!工作保護密碼破解」這個宏後，
解除工作表的密碼保護了

③ Excel文件忘記密碼怎麼辦
1.開啟excel文件點擊撤銷工作簿保護時忘記密碼的情況,
2.這時就可以右鍵文件,開啟右鍵菜單列表,
3.點擊重命名把文件後綴改成rar,
4.改成完rar使用壓縮應用打開這個rar文件,
5.然後打開xl目錄下的worksheets文件夾,
④ Excel文件忘記密碼怎麼辦
可以通過以下步驟解除Excel加密密碼：
所需材料：Excel、記事本、解壓軟體。
一、首先點擊選中被加密的表格文檔，按F2重命名，把文件格式改為RAR。
⑤ 如何解鎖excel中的密碼忘了怎麼辦
Excel保護密碼若是忘記，可通過以下步驟進行解鎖：
所需材料：解壓軟體（這里用的WINRAR）、Excel2007演示。
一、下圖中這個表格文件被保存，雙擊表格內單元格內會彈出該表格為只讀，那麼開始破解該表格。
注意事項：
1、第五步查找的內容「sheetPro」中，「P」必須是大寫，其他字母必須全部為小寫，否則找不到。
2、第六步選中的是「sheetPro」所在尖括弧內的全部內容，包含尖括弧。
3、若是使用能夠在壓縮包內修改的壓縮軟體，第三步可跳過，直接在壓縮包內進行修改。
