COUNTIF函數常規用法

生活百科小知識

一、求各種類型單元格的個數
(1)求真空單元格單個數:=COUNTIF(data,"=")
(2)真空+假空單元格個數:=COUNTIF(data,"")相當于countblank()函數
(3)非真空單元格個數:=COUNTIF(data,"<>")相當于counta()函數
(4)文本型單元格個數:=COUNTIF(data,"*")假空單元格也是文本型單元格
(5)區域內所有單元格個數:=COUNTIF(data,"<>""")
(6)邏輯值為TRUE的單元格數量：=COUNTIF(data,TRUE)
小說明：
EXCEL單元格內數據主要有以下幾類:數值型,文本型,邏輯型,錯誤值型 。其中時間類型也是一種特殊的數值 。文本類型的數字是文本型 ?？諉卧瘢褐甘裁磧热菀矝]有的單元格，姑且稱之為真空 。假空單元格：指0字符的空文本，一般是由網上下載來的或公式得來的，姑且稱之為假空 。date指單元格區域，該參數不能是數組 。
二、求><=某個值的單元格個數
(1)大于50：=COUNTIF(data,">50")
(2)等于50：=COUNTIF(data,50)
(3)小于50：=COUNTIF(data,"<50")
(4)大于或等于50：=COUNTIF(data,">=50")
(5)小于或等于50：=COUNTIF(data,"<=50")
(6)大于E5單元格的值：=COUNTIF(data,">"&$E$5)
(7)等于E5單元格的值：=COUNTIF(data,$E$5)
(8)小于E5單元格的值：=COUNTIF(data,"<"&$E$5)
(9)大于或等于E5單元格的值：=COUNTIF(data,">="&$E$5)
(10)小于或等于E5單元格的值：=COUNTIF(data,"<="&$E$5)
三、等于或包含某N個特定字符的單元格個數
(1)兩個字符：=COUNTIF(data,"??")
(2)兩個字符并且第2個是B:=COUNTIF(data,"?B")
(3)包含B:=COUNTIF(data,"*B*")
(4)第2個字符是B:=COUNTIF(data,"?B*")
(5)等于“你好”:=COUNTIF(data,"你好")
(6)包含D3單元格的內容:=COUNTIF(data,"*"&D3&"*")
(7)第2字是D3單元格的內容:=COUNTIF(data,"?"&D3&"*")
注：countif()函數對英文字母不區分大小寫，通配符只對文本有效
四、兩個條件求個數
(1)>10并且<=15=SUM(COUNTIF(data,">"&{10,15})*{1,-1})
(2)>=10并且<15=SUM(COUNTIF(data,">="&{10,15})*{1,-1})
(3)>=10并且<=15=SUM(COUNTIF(data,{">=10",">15"})*{1,-1})
(4)>10并且<15=SUM(COUNTIF(data,{">10",">=15"})*{1,-1})
注：一般多條件計數使用SUMPRODUCT函數，以上方法較少使用，僅供參考 。
補充：三個區域計數：三個區域中=60
【COUNTIF函數常規用法】五、各種特殊統計要求的計算A1:A100為存放數據的區域
(1)非空文本(僅包括可鍵入文本:=COUNTIF(A1:A100,">=!")
(2)所有非空文本=COUNTIF(A1:A100,">=!")+COUNTIF(A1:A100,">="&CHAR(1))-COUNTIF(A1:A100,">=")或{=SUM(COUNTIF(A1:A100,">="&{"!",""})*{1,-1})+COUNTIF(A1:A100,">="&CHAR(1))}即文本型-含" "(空格)數量
(3)全部可見單元格{=SUM(N(IF(ISERROR(A1:A100),1,SUBSTITUTE(A1:A100," ",""))<>""))}，即全部看上去不是空值的單元格(=全部記錄-真空-空格)
(4)有效可見單元格=COUNTIF(A1:A100,">=!")+COUNTIF(A1:A100,">="&CHAR(1))-COUNTIF(A1:A100,">= ")+COUNT(A1:A100)，即所有非空文+數字型數據之和
(5)全部不見單元格(真空+空格+空文本)=COUNTIF(A1:A100,"")+COUNTIF(A1:A100,">=!")+COUNTIF(A1:A100,">=")
(6)空格=COUNTIF(A1:A100,">=")-COUNTIF(A1:A100,">=!")
