excel表格怎样设置禁止编辑图文教程

  如何使excel表格内容只读不能修改及破解,具体该怎么去进行操作的呢?对于刚从其它版本转型过来的应该就不会太懂吧,没关系,接下来小编就教大家在Excel2010表格设置不可修改的方法。

  Excel2010表格设置不可修改的方法

  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。

  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 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(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。

  把上面的代码保存为一个宏,运行,点两次确定,等到它运行结束,工作表密密码就解除了。

  ★如果出现提示“工程不可查看”不能录制新宏,可以先使用“VBA工程加锁解锁器”来解除其“工程不可查看”后再用上面的方法找出保护密码。

  当然了,“VBA工程加锁解锁器”顾名思义,这是一个既可以解除Excel保护密码,又可以为Excel加保护密码的软件,实为一个优秀的Excel辅助工具。

  四、解除工作簿的保护

  如果工作簿被密码保护不能打开,我们可以也使用一些专用的破解软件进行破解

  如果只能以只读方式打开,我们打开后另存为一个不设密码的副本,即可解除只读限制。

  有时虽然工作簿在打开时没有任何密码,但如果我们不能对工作表进行复制、移动和插入等操作,那是保护了工作簿,可以通过依次选择“工具→保护→撤消工作簿 保护”菜单命令来解除,但如果有密码的话,能够猜出来更好,否则只有新建一工作簿,将被保护的工作表内容用拖选的方法复制到新的工作簿中进行编辑。

  相信有了上面这些方法,Excel中应该没有多少东西能够瞒过你的火眼金睛,也没有多少内容让你不能左右了。
