相信大家总能在朋友圈刷到下图这种教育广告，python很强，但总是这么贬低Excel就没必要了吧。

直到我看见了下面的回复，笑喷！![format_png 2][]

![format_png 3][]

实话实说，从数据分析的角度来看，excel的可视化要差一些，数据采集也不能跟python相比，这都不是excel的专业，但是excel在数理统计上的表现还是很不错的

所以当数据分析量小、想要快速出结果、逻辑关系简单的情况下，excel很香！\[1\]

而python就是给你一堆原材料，水泥、砖头、钢筋等等，你的工作就是自己要从头摘，一步步把高楼给建造出来。

Excel虽然人人都会，但如果想要用来数据分析，要掌握的函数操作还真不少。

下文是Excel常用函数大全，建议收藏，不要吃灰！

文末三连不要忘了哈![format_png 4][]（阅读、在看、分享）

> 这是一份很好的Excel常用函数大全，也是工作中经常使用的函数操作，学习Excel常用函数，不要求面面俱到，而是选择常用的函数进行学习，当再次碰到了其它函数，再单独去学习即可。       ——黄同学

## 1、excel函数需要掌握的基础功能 ##

下面都是在使用Excel过程中，所使用过的一些基础功能，限于篇幅这里就不详细介绍，大家可以自行下去操作一遍。

*  相对引用
 *  绝对引用
 *  帮助功能
 *  显示公式
 *  自动/手动计算
 *  追踪引用单元格
 *  名称编辑器
 *  照相机

## 2、函数分类 ##

![format_png 5][]

## 3、学习函数的建议 ##

*  不要死记硬背，但是看着某些函数一定要眼熟。
 *  学会使用在线帮助功能(按F1键)。
 *  合理的逻辑思维，excel中函数的使用，和我们学习其他编程语言中使用函数一样，了解函数的功能、参数。

## 4、绝对引用、相对引用与半绝对引用 ##

### 1）图示讲解含义 ###

注意：使用F4键，进行绝对引用和相对引用公式的切换。![format_png 6][]

上图我们已经演示了“相对引用”和“绝对引用”的功能，那么到底什么是“相对引用”？什么又是“绝对引用”呢？下面我们分别对其下一个定义。

在定义这两个概念之前，我们先来说明一下excel中的行与列。从上图可以看出，在excel中，行索引是一系列的数字(1,2,3...)，列索引是一系列的大写字母(A,B,C...)，。但是我们在表述某一个单元格时，常喜欢用类似“C2”的形式，表示某一个单元格，即把列写在前面，行写在后面。

相对引用：针对某一单元格引用另外一个单元格的情况，不添加“ $ ”符号时，就表示相对引用。当我们将引用单元格，朝着右边、下边拖动填充的时候，该引用单元格会跟着被引用单元格变化，类似于图中的“A图”。

绝对引用：也是针对某一单元格引用另外一个单元格的情况，行列都添加“ $ ”符号时，就表示绝对引用。当我们将引用单元格，朝着右边、下边拖动填充的时候，引用单元格不发生任何变化，类似于图中的“B图”。

半绝对引用：同样是针对某一单元格引用另外一个单元格的情况，行或者列其中一个添加“ $ ”符号时，就表示半绝对引用。当仅针对行使用了“ $ ”符号，引用单元格朝下边拖拉填充的时候，引用单元格不会发生任何变化，类似于图中的“C图”。当仅针对列使用了“$”符号，引用单元格朝右边拖拉填充的时候，引用单元格不会发生任何变化，类似于图中的“D图”。

### 2）利用九九乘法表讲述“绝对引用”和“相对引用” ###

#### ① 最简单的一种 ####

![format_png 7][]        从上述案例可以看出，我们在B41单元格输入了“=$A41\*B$40”这个公式，这个公式表示B41单元格分别引用了“$A41和B$40”这两个单元格，但是为什么是在A和40前面加“$”符号呢？这个需要我们好好琢磨一下。

我们可以先想象一下，当单元格B41从做左右拖拉填充的时候，是不是保持了“A41行不变，B40列变化”，因此40前面需要加一个“$”符号。当单元格B41从上往下拖拉填充的时候，是不是保持了“B40列不变，A41行变化”，因此40前面需要加一个“$”符号。

#### ② 使用“&”连接符，显示较全的九九乘法表 ####

![format_png 8][]

#### ③ 配合if()函数，显示上/下三角形式的九九乘法表 ####

![format_png 9][]

## 5、函数讲解(最常用的个函数) ##

使用函数之前，学会下方的四个提示和一个注意：  一：所有的函数均是以“=”开头；  二：所有的函数都是在“英文”状态下输入；  三：文本或日期等非单元格的引用，需要添加“双引号”；  四：连接符是“&”；  注意：在excel单元格中，数字和日期都是靠着单元格右侧，文本都是靠着单元格左侧。![format_png 10][]

### 1）逻辑函数 ###

#### ① and ####

![format_png 11][]

#### ② or ####

![format_png 12][]

#### ③ if ####

![format_png 13][]当使用了if()函数进行多层嵌套，很容易写错，那么怎么规避这个问题呢？![format_png 14][]

### 2）字符串函数 ###

#### ① left ####

![format_png 15][]

#### ② right ####

![format_png 16][]

#### ③ mid ####

![format_png 17][]

#### ④ len(lenb自己下去学习) ####

![format_png 18][]

注意：len = 1中文 + 1英文；lenb = 2中文 + 1英文；这两个函数可以完成中英文的分离。len - lenb表示的是中文个数；2len - lenb表示的是英文个数。

#### ⑤ lower ####

![format_png 19][]

#### ⑥ upper ####

![format_png 20][]

#### ⑦ proper ####

![format_png 21][]

#### ⑧ find ####

注意：find()函数区分大小写，search()函数不区分大小写。![format_png 22][]

#### ⑨ search ####

注意：find()函数区分大小写，search()函数不区分大小写。![format_png 23][]

#### ⑩ rept ####

![format_png 24][]

#### ⑪ replace ####

![format_png 25][]

#### ⑫ substitute ####

注意：这个函数的最后一个参数很有用。如果一个文本中有几个重复的内容，最后一个参数可以指定，从第几个重复内容开始起，进行替换。![format_png 26][]

#### ⑬ trim ####

注意：该函数可以去掉字符串中所有的空格，但是会保留一个字符与字符之间的间隔空白符。![format_png 27][]

### 3）数学函数 ###

#### ① abs ####

![format_png 28][]

#### ② round ####

![format_png 29][]

#### ③ roundup ####

![format_png 30][]

#### ④ rounddown ####

![format_png 31][]

#### ⑤ even ####

注意：enen和odd都是朝着绝对值数字大的方向走的。![format_png 32][]

#### ⑥ odd ####

注意：enen和odd都是朝着绝对值数字大的方向走的。![format_png 33][]

#### ⑦ int ####

![format_png 34][]

#### ⑧ trunc ####

![format_png 35][]

#### ⑨ power ####

![format_png 36][]

#### ⑩ ^ ####

![format_png 37][]

#### ⑪ product ####

![format_png 38][]

#### ⑫ mod ####

![format_png 39][]

#### ⑬ rand ####

![format_png 40][]

#### ⑭ randbetween ####

![format_png 41][]

### 3）统计函数 ###

#### ① sum\_sumif\_sumifs ####

![format_png 42][]

#### ② average\_averageif\_averageif\_averagea ####

注意：averagea()函数用法较为特殊，需要特别留意一下即可。![format_png 43][]

#### ③ count\_countif\_countifs\_counta\_countblack ####

![format_png 44][]

#### ④ max\_maxa\_min\_mina\_median ####

![format_png 45][]

#### ⑤ sumproduct ####

![format_png 46][]

#### ⑥ subtotal ####

注意：这个函数可以实现我们之前学过的很多函数的功能，用起来也很方便，由于该函数涉及到的知识点太多，这里简单介绍一下。我们在excel中输入该函数，会有这么多提示：![format_png 47][]

下面介绍一些操作展示：![format_png 48][]

### 4）时间函数 ###

#### ① today\_now：返回系统时间 ####

![format_png 49][]

#### ② year\_month\_day：提取某个日期中的年、月、日 ####

![format_png 50][]

#### ③ days\_datedif：计算两个日期之间的年、月、日 ####

![format_png 51][]

#### ④ edate\_eomonth：将时间前、后移动指定月份 ####

![format_png 52][]

#### ⑤ weekday：返回星期几的函数 ####

这个函数需要特别注意一下，默认情况下，显示的是国外的时间，也就是说星期天显示的是1。但是我们国家希望星期天显示的是7，星期一显示的是1，怎么办呢？我猜你肯定不知道，weekday()函数还有第二个参数，如下图所示。![format_png 53][]

今天是2020年5月1号，按照国外默认来说，今天应该是周六，即显示结果为6。如果使用了第2个参数后，可以改成我们习惯的“星期”显示方式。![format_png 54][]

#### ⑥ text：返回各种日期、时间格式的函数(强大) ####

text()函数相当强大、有用，涉及到的知识点也是众多的，因此这里提供一个学习链接给大家，就不详细演示了：https://baijiahao.baidu.com/s?id=1615357210194597308&wfr=spider&for=pc\[2\]

![format_png 55][]

#### ⑦ networkdays\_networkdays.inl：计算工作日的常用函数 ####

![format_png 56][]

关于networkdays.inl的第4个参数，很有用，我们利用下图进行展示一下，从下图可以看出，每一个数字代表每一周的休息日是哪一天，例如“数字11”表示，休息日只有星期天，周六仍然需要上班，这就是我们所说的“单休”。![format_png 57][]

### 5）行数、列数统计函数 ###

#### ① column\_columns\_row\_rows ####

![format_png 58][]

### 6）匹配查找函数 ###

#### ① vlookup ####

注意：多条件查询，需要添加辅助列。![format_png 59][]

#### ② lookup及其高级应用 ####

注意：使用lookup()函数需要特别注意，“查找对象所在的列必须升序排列”，否则结果做出来都是错的。同时，这个进行多条件查询的时候，不需要添加辅助列。![format_png 60][]

假如，我不想改动源数据，仍然想要使用lookup()做查找，应该怎么办呢？那么就需要使用lookup()高级应用了。关于lookup()高级应用，这里需要记住一句话：首先它会默认你的查找区域是升序排列，当查找值在查找区域中找不到目标值的时候，就会返回该区域中的“最大值”，这就是下面要讲述方法的“解题关键”。![format_png 61][]

#### ③ index ####

![format_png 62][]

关于index()函数显示某一行值，涉及到数组的操作，下面我们录制了一个视频。![format_png 63][]

#### ④ match ####

![format_png 64][]

注意：index()和match()进行搭配使用，进行多条件查找，相当有效，也特别好用。组合棋类的效果是这样的：index(查找区域，行号，列号)。

#### ⑤ offset ####

![format_png 65][]

### 7）错误处理函数 ###

#### ① iferror ####

![format_png 66][]
