excel密码解密？1.打开 Excel ：打开 Microsoft Excel ，然后点击菜单栏的 "文件"。2.寻找加密文件：在文件菜单中选择 "打开"，然后浏览你的计算机或文档文件夹，找到加密的 Excel 文件。那么，excel密码解密？一起来了解一下吧。
如果是打开密码，就是文件一打开就提示要求输入密码，而不是在修改或者删除的时候提示要密码。这种情况只能用Excel文件的解密，网上可型橡以搜得到的，但是你至少需要知道设置的密码是6位数还是8位数，或者是2位数。不然这类只能用穷举法来帮你解密，从1、2、3......999999，这还只是6位数，如果是8位数，你可以想想有多少种组合？再加上52个英文字母（大小写），还有英文字母加数字。。。。。。想想都觉得恐怖。普通的家庭电脑来做这个工作的话，应该可以算到电脑报废吧。。。
其实哪怕是你知道是几位数的密码，组合也是非常非常的多。此类无法用其他方式来处理的问题一般都由大型的服务器机群来完成。脊租握。当然还有一种简单点樱庆的方法，MSoffice加的密，你就问微软公司，他们是一定知道如何解开或者说跳过。有什么要求那我就不知道了。
在Excel中经常碰到一些加密了的文档，如果觉得每次打开都嫌麻烦就需要把密码给撤销了。下面是由我分享的如何解除excel加密的方法，希望对你有用。
解除excel加密的方法解除加密步骤1：在excel里点击文件，另存为命令。
解除加密步骤2：为文件指定保存地址。
解除加密步骤3：指定好保存地址和文件名后，点击常规选项。

解除加密步骤4：将打开权限密码或者修改权限密码删除，确定，然后保存即可。

EXCEL中求某一区域内不重复的数据个数
例如求A1:A100范围内不重复数据的个数，某个数重复多次出现只算一个。有两种计算方法：
一是利用数组公式：
=SUM(1/COUNTIF(A1:A100,A1:A100))
输入完公式后按Ctrl+Shift+Enter键,让它自动加上数组公式符号"{}"。
二是利用乘搏颂积求和函数：
=SUMPRODUCT(1/COUNTIF(A1:A100,A1:A100))
excel在已有的单元格中批量加入一段固定字符的方法
例如：在单位的人事资料，在excel中输入后，由于上级要求在原来的职称证书的号码全部再加两位，即要在每个人基坦郑的证书号码前再添上两位数13，如果一个一个改的话实在太麻烦了，那么我们可以用下面的办法，省时又省力：
1)假设证书号在A列，在A列后点击鼠标右键，插入一列，为B列;
2)在B2单元格写入： ="13" &信型 A2 后回车;
使用以衡戚下步骤进行破解被保护的工作表：
所需材料：记事本、Excel。
一、首先点击被保存的工作薄，按F2重命名，格式改为RAR。
二、这时表格会变为一个压缩包，打开该压缩包，打开后双击打开XL文件夹。
三、然后再双击打开Worksheets文件夹。
四、打开该目录后，把被保护工作表拖至桌面。
五、接着使用记事本打开该文件。
六、打开该文件后，Ctrl+F键打开查找窗口，输入Protection，点击查找下一个。
七、找到后，选中其所在尖括号内的全部内容（包括前后两个尖括号），按Del键删除这串字符，按Ctrl+S保存，保存后关闭记事本。
八、接着把已经修改完的文件再次拖入压缩包当前目录内。
九、弹出的替换简拦陪文件窗口内点击替换。
十、再次点击压缩包，按F2键重命名，格拦蠢式改为XLSX表格格式。
十一、这时打开该工作薄，进入审阅选项卡下，撤消工作薄保护按钮消失，破解完成。
