Excel快速输入www.Tulaoshi.com带多位0的数字
①如下图所示，我们要在C列中输入D列单元格的数字，首先在C2单元格输入2**6，表示2后面6个0.
②然后回车，下面的两项按同样的方法输入。
③选中C列，单击菜单栏--开始---数字功能组中的小三角，从下拉菜单中单击常规无特定格式。
④OK完成，这样输入比我们手动键入0要方便多了，手动键入难免会输入少或者输入多，这个方法用起来就不会出错。
如何使用excel单元格一键批量录入
tulaoshi.com具体解决方法如下:
第一步， 选定多个单元格
第二步，使用键盘输入需要重复的信息
第三步，ctrl+enter
Excel2010如何快速求出各月最晚数据总和
1、打开要进行求和的表格，选中D列，单击菜单栏--数据--升序按钮。
2、弹出排序提醒对话框，选择扩展选定区域，开始排序。
3、然后在辅助列E2单元格输入公式： =VLOOKUP(EOMONTH(D2,0),$D$2:$D$9,1)=D2 公式1的意义我之后为大家讲解。
4、回车得到结果FALSE，鼠标移动到右下角，出现+号填充柄，双击，将整个数据填充完毕。
5、然后在G2单元格输入： =SUMIF(E2:E9,"TRUE",C2:C9) 作为公式2.
7、结果显示217，下面我们来看看是不是正确，凭眼力找到7、8、9月份最晚的数据，Ctrl键选中，改为红色，从下方的状态栏里面可以清清楚楚的看到求和结果为217，验证了公式的正确性。
公式意义
公式1：首先，eomonth函数会返回月份的最后一天，例如，7月份的最后一天是31号，然后，vlookup函数会匹配出最接近最后一天的日期，最后，在判断是否和D2单元格相等。

如何快速提取Excel小数点后第N位数字
①启动Excel2007，打开需要处理的数据清单，在F2单元格输入下面的公式。
②回车得到结果7，公式的意思是向右取2位小数，也就是7。
③在验证结果准确无误之后，我们放心的双击单元格填充柄，将余下的进行计算。
④如果结果显示乱码，请讲填充设置为不带格式填充，这样结果都会准确。
