1.首先，打开受保护的Excel表格，按“ALT”+“F11”键，弹出如下的界面。

2.点击“插入”——“模块”，出现下图。

3.复制文中的代码，粘贴到空白区域；

4.点击“F5”运行宏模块，进行密码破解，出现如下图，密码为图中的圈圈。

5.经过以上的步骤，此Excel的表格的密码已经自动除去。

Excel表格密码保护的解除方法 关键字：office2003 office2007 宏 密码保护 表格受密码保护时，我们修改数据Excel弹出“您试图更改的单元格或图表受保护，因而是只读的。若要修改受保护单元格或图表，请先使用‘撤消工作表保 护’命令(在‘审阅’选项卡的‘更改’组中)来取消保护。可能会提示您输入密码。这时候我们可以用VBA宏代码破解法来破解表格保护密码： 第一步： Office2003打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“Microsoft Office安全选项”窗口，选择其中的“启用此内容”，“确定”。再切换到“视图”选项卡，点击“宏”→“录制宏”，出现“录制新宏”窗口，在“宏名” 定义一个名称为：PasswordBreaker，点击“确定”退出； Office2007默认是不显示开发工具栏的，在excel窗口最顶端右键点击“custome quick access tool<自定义快捷工具栏>”---》在新窗口中点击“Popular<常用>”---》选择右侧的“show developer tab in the ribbon”,确定；在新出现的developer工具栏，点击“macro security ”,然后选择新窗体中的“enable all macros (not recommands...)” 第二步：再点击“宏”→“查看宏”，选择“宏名”下的 “PasswordBreaker”并点击“编辑”，打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗口中的所有代码： Sub PasswordBreaker() Dim i As Integer, j As Integer, k As Integer Dim l As Integer, m As Integer, n As Integer Dim i1 As Integer, i2 As Integer, i3 As Integer Dim i4 As Integer, i5 As Integer, i6 As Integer On Error Resume Next For i = 65 To 66: For j = 65 To 66: For k = 65 To 66 For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66 For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66 For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126 ActiveSheet.Unprotect_chr(i) &_chr(j) &_chr(k) & _ Chr(l) &_chr(m) &_chr(i1) &_chr(i2) &_chr(i3) & _ Chr(i4) &_chr(i5) &_chr(i6) &_chr(n) If ActiveSheet.ProtectContents = False Then MsgBox "One usable password is " &_chr(i) &_chr(j) & _ Chr(k) &_chr(l) &_chr(m) &_chr(i1) &_chr(i2) & _ Chr(i3) &_chr(i4) &_chr(i5) &_chr(i6) &_chr(n) ActiveWorkbook.Sheets(1).Select Range("a1").FormulaR1C1 =_chr(i) &_chr(j) & _ Chr(k) &_chr(l) &_chr(m) &_chr(i1) &_chr(i2) & _ Chr(i3) &_chr(i4) &_chr(i5) &_chr(i6) &_chr(n) Exit Sub End If Next: Next: Next: Next: Next: Next Next: Next: Next: Next: Next: Next End Sub 第三步：再点击“宏”→“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“执行”，密码就现形了 第四步：点击“撤消工作表保护”，然后输入密码即可解除锁定； 测试结果，密码破解可用，但是很晕的是破解的密码跟原来的密码有很大的差距，想不明白了，反正能用就好。

把需要的内容选中，然后复印一下，重新打开一个新单元格右键选择键粘贴－数值，就行了。
如果是要在原文档上改比较麻烦，但上述方法也行，只需要重新把版面设置一下就可以

去申诉吧，用别的问题保护去掉也行。
