SUBSTITUTE函数的基础语法是:
SUBSTITUTE(要替换的文本,旧文本,新文本,[替换第几个])
最后一个参数,[替换第几个], 是可以省略的。
举几个小栗子,和大家分享下SUBSTITUTE函数的常用技巧和套路。
1,将数据中的某个值替换为另一个值
比如将B列数据里的二班,替换为一班。
C2输入公式,并向下复制填充:
=SUBSTITUTE(B2,"二班","一班")
这里没啥好解释的了,就是将B列中单元格中的“二班”全部替换为“一班”。
2,隐藏手机号的中间5位
C2输入公式,并向下复制填充:
=SUBSTITUTE(B2,MID(B2,4,5),"*****")
先使用MID函数取得B列号码中的中间五位,再用字符串“*****”替换掉这部分内容。
3,对含单位的数据求和
B7输入公式:
=SUMPRODUCT(SUBSTITUTE(B2:B6,"人",)*1)
先用SUBSTITUTE替换掉B列单元格中的“人”,得到文本型数字,乘以1后转换成可以计算的数值,再用SUMPRODUCT函数进行求和。
4,数据分列,将B列数据按顿号进行分列
C2单元格输入公式横向拖动,并向下复制填充。
=TRIM(MID(SUBSTITUTE($B2,"、",REPT(" ",100)),COLUMN(A1)*100-99,100))
REPT(” “,100)
先使用REPT函数,将空格重复100次,得到100个空格。
SUBSTITUTE($B2,”、”,REPT(” “,100))
使用SUBSTITUTE函数将姓名中的的间隔符号顿号替换为100个空格。
MID(SUBSTITUTE($B2,”、”,REPT(” “,100)),COLUMN(A1)*100-99,100)
再使用MID函数,依次从带有空格的新字符串中的第1、第101、第201位……截取长度为100的字符。
这样得到的字符串是带有多余空格的,因此再使用TRIM函数将多余空格删除掉。
5,混合文本中,计算人数个数
B2公式:
=LEN(A2)-LEN(SUBSTITUTE(A2,"、",))+1
LEN(A2)取得A2字符串的长度。
LEN(SUBSTITUTE(A2,”、”,))+1,替换掉人名之间的间隔符,也就是顿号,再用LEN计算该值的长度,最后加1,是因为最后一个人名没有顿号。
用A2数值原有的长度减去被替换掉人名之间间隔符的长度,也就是人名的个数。
6,混合文本中,计算数值最大值。
B2数组公式:
=MAX((SUBSTITUTE(A2,ROW($1:$98),)<>A2)*ROW(1:98))
SUBSTITUTE(A2,ROW($1:$98),)<>A2
依次将数值1到98从A2替换为空,然后把替换后的结果和被替换值(1-98)进行比较 ,如果不相等,则证明A2中存在该数值。
最后将上述部分公式的运算结果,也就是逻辑值TRUE和FALSE,乘以被替换的值(1-98),用MAX函数从中取得最大值。
7,计算某个值在某个范围的最大连续次数
B2数组公式:
=MAX((SUBSTITUTE(PHONETIC(A2:A9),REPT("A",ROW(1:9)),)<>PHONETIC(A2:A9))*ROW(1:9))
PHONETIC(A2:A9)
将A2:A9的文本值黏合成一个值,以便SUBSTITUTE函数进行操作。
REPT(“A”,ROW(1:9))
把“A”重复1到9次。
SUBSTITUTE(PHONETIC(A2:A9),REPT(“A”,ROW(1:9)),)<>PHONETIC(A2:A9)
思路回到示例6,SUBSTITUTE函数将REPT函数的运算结果,在PHONETIC函数的运算结果里替换掉,然后和PHONETIC函数的原值进行比较。如果后者存在替换值,则被替换掉,此时和原值不相等,返回FALSE,否则返回TRUE。
最后依然把上述公式返回的逻辑值TRUE和FALSE,分别乘以ROW(1:9),用MAX函数从中取得最大值。

Most users use Excel to process table data. In fact, Excel also has a VBA program. Apart from experts, not many users have used this function. The iif function is often used when writing in VBA. It is actually the same as if The functions of the functions are similar. Let me introduce to you the usage of the iif function. There are iif functions in SQL statements and VBA code in Excel. The iif function is similar to the IF function in the excel worksheet. It performs true and false value judgment and returns different results based on the logically calculated true and false values. IF function usage is (condition, yes, no). IF statement and IIF function in VBA. The former IF statement is a control statement that can execute different statements according to conditions. The latter
