一、求各种类型单元格的个数
(1)求真空单元格单个数:=COUNTIF(data,"=")
(2)真空+假空单元格个数:=COUNTIF(data,"")相当于countblank()函数
(3)非真空单元格个数:=COUNTIF(data,"<>")相当于counta()函数
(4)文本型单元格个数:=COUNTIF(data,"*")假空单元格也是文本型单元格
(5)区域内所有单元格个数:=COUNTIF(data,"<>""")
(6)逻辑值为TRUE的单元格数量：=COUNTIF(data,TRUE)
小说明：
EXCEL单元格内数据主要有以下几类:数值型,文本型,逻辑型,错误值型。其中时间类型也是一种特殊的数值。文本类型的数字是文本型。空单元格：指什么内容也没有的单元格，姑且称之为真空。假空单元格：指0字符的空文本，一般是由网上下载来的或公式得来的，姑且称之为假空。date指单元格区域，该参数不能是数组。
二、求><=某个值的单元格个数
(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单元格的值：=COUNTIF(data,">"&$E$5)
(7)等于E5单元格的值：=COUNTIF(data,$E$5)
(8)小于E5单元格的值：=COUNTIF(data,"<"&$E$5)
(9)大于或等于E5单元格的值：=COUNTIF(data,">="&$E$5)
(10)小于或等于E5单元格的值：=COUNTIF(data,"<="&$E$5)
三、等于或包含某N个特定字符的单元格个数
(1)两个字符：=COUNTIF(data,"??")
(2)两个字符并且第2个是B:=COUNTIF(data,"?B")
(3)包含B:=COUNTIF(data,"*B*")
(4)第2个字符是B:=COUNTIF(data,"?B*")
(5)等于“你好”:=COUNTIF(data,"你好")
(6)包含D3单元格的内容:=COUNTIF(data,"*"&D3&"*")
(7)第2字是D3单元格的内容:=COUNTIF(data,"?"&D3&"*")
注：countif()函数对英文字母不区分大小写，通配符只对文本有效
四、两个条件求个数
(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：一般多条件计数使用SUMPRODUCT函数，以上方法较少使用，仅供参考。
补充：三个区域计数：三个区域中=60
五、各种特殊统计要求的计算A1:A100为存放数据的区域
(1)非空文本(仅包括可键入文本:=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)数量
(3)全部可见单元格{=SUM(N(IF(ISERROR(A1:A100),1,SUBSTITUTE(A1:A100," ",""))<>""))}，即全部看上去不是空值的单元格(=全部记录-真空-空格)
(4)有效可见单元格=COUNTIF(A1:A100,">=!")+COUNTIF(A1:A100,">="&CHAR(1))-COUNTIF(A1:A100,">= ")+COUNT(A1:A100)，即所有非空文+数字型数据之和
(5)全部不见单元格(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,">=!")
(7)空文本""=COUNTIF(A1:A100,"")-COUNTIF(A1:A100,"=")
(8)逻辑与错误=COUNTIF(A1:A100,"<>")-COUNTIF(A1:A100,"*")-COUNT(A1:A100)
