excel表格内容只读不能修改及破解.doc

excel表格内容只读不能修改及破解只读不能修改方法:在EXCEL里，选择工具选项安全性分别设置打开权限密码和修改权限密码，2个密码要不一样，然后确定，会弹出对话框让你重新输入密 码，第一个框输入你设置打开权限密码，第二个框输入你修改权限密码，然后保存文件。然后你把打开权限密码给别人就OK了，别人打开就是只读，不能修改。要 修改需要你修改权限密码。补充一下：如果不想只读打开需要密码，可以不设置打开权限密码，只设置修改权限密码。破解Excel保护方法Excel对数据有很强的保护功能，可以对整个或部分数据隐藏、禁止复制和修改等，但有时候，由于忘记了密码，或者记不起以前自己到底做了哪些改动，这种保护反而会为难自己。针对这种情况，我总结了几种解除保护的方法，供大家参考，并希望能够以此抛砖引玉。一、解除单元格的保护1取消隐藏的行或列 被隐藏的行或列有一个明显的标志，那就是在行标题栏或列标题栏上有一条粗的黑线。取消隐藏的行或列的方法有两种，一种是直接拖动隐藏处的行或列标题使之变 宽，也可以选中包含隐藏区域的行或列，通过“格式”菜单中的行列项目输入非0数值调整行高或列宽，使数据有足够的空间显示出来；另一种方法是选中包含隐藏 内容的行或列区域，再通过“格式”菜单行列选项中的“取消隐藏”命令来恢复全部行列区域。2取消隐藏单元格或区域中的数据 为了不让他人直接看到单元格的内容，一种简单的方法就是把数据颜色设置成与背景色相同，这时我们只要拖选整个工作表即可让数据原形毕露；如果用图片、矩形 框之类的非字符内容将重要数据遮盖，需要先用拖选方式找出工作表中的图片位置，再将其移开，激活被遮住的单元格，一般在公式编辑栏中就会显示其内容。 若在单元格格式中使用了三个分号或空格之类的自定义格式，一般只要选中此单元格，在公式编辑栏中即可显示其内容，要想取消这种隐藏，可重新设置此单元格格式，在“数字”选项卡中选择“常规”即可。 如果选中怀疑有数据的单元格后并没有在公式编辑栏中显示数据，不一定它就真的没有数据，我们只要看一下单元格的格式能否设置，若不能的话说明工作表被保 护，如果不用密码可以取消工作表保护的话，再在单元格格式设置中先查看数据格式是否为自定义，然后查看“保护”选项卡，看看是否已勾选了“隐藏”项，将这 些都取消就可以知道单元格是否真的没有内容。当然，如果在撤消工作表保护时需要密码的话，我们将无可奈何，除非用户设置的密码很简单，那我就告诉你一个秘 密，当密码的形式是“*123*”或“*abc*”时，我们可以分别用“*333*”或“*ccc*”来破解，星号表示任意字符，到底是什么只有靠猜了， 这种方法对工作表和工作簿保护的密码也适应。3取消单元格数据的只读属性 有时单元格中的数据虽然可见，但是我们既不能修改，也不能在当前工作表中复制，对于这种保护措施，取消的方法跟上面的第2点基本相同，只要取消单元格格式 设置对话框中“保护”选项卡中的“锁定”一项即可。当然还需要通过密码取消工作表的保护才行。 如果我们无法通过密码取消怎么办？你可以将其复制粘贴到其他工作表中，再在新的工作表中进行修改。二、解除工作表的保护 查看是否有被隐藏的工作表，若菜单中有“格式工作表取消隐藏”项，则可通过此项取消隐藏的工作表。 如果在菜单中也没有有效的“取消隐藏”项，仍然可能有被隐藏的工作表，这时我们可以任选一工作表右击，在弹出菜单中选择“查看代码”，然后在左窗格中的 “Microsoft Excel 对象”列表中选择被隐藏的工作表，将其“Visible”属性值取“-1”退出即可，如图所示。 如果工作表被密码保护，则可复制当前表全部内容到另一张未保护的工作表中编辑。 Windows8官方下载 三、VBA宏代码破解法： 第一步：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”退出(图2)；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(图3)，点击“确定”退出；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 IntegerDim l As Integer, m As Integer, n As IntegerDim i1 As Integer, i2 As Integer, i3 As IntegerDim i4 As Integer, i5 As Integer, i6 As IntegerOn Error Resume NextFor i = 65 To 66: For j = 65 To 66: For k = 65 To 66For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126ActiveSheet.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 ThenMsgBox 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).SelectRange(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 SubEnd IfNext: Next: Next: Next: Next: NextNext: Next: Next: Next: Next: NextEnd 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(图4)。第四步：切换“审阅”选项卡，点击“撤消工作表保护”，然后输入密码即可解除锁定。 win7旗舰版系统下载 另一个能解除Excel工作表保护的VBA脚本 Option ExplicitPublic Sub AllInternalPasswords() Breaks worksheet and workbook structure passwords.
