EXACT函数是否在数组公式中返回“＃N / A”错误？

Question

当我将公式应用于范围B3：B7时，它可以很好地工作。当我将公式应用于范围B4：C4时，效果并不理想。该公式将检测范围内的小写字母。

垂直：=IF(SUM(EXACT(IFERROR(LEFT(RIGHT(B3:B7,LEN(B3:B7)-SEARCH(" ",B3:B7,1)),2),""),{"Bb","Yb","Zb","Eb","Pb","Tb","Gb","Mb","Kb","bB","yB","zB","eB","pB","tB","gB","mB","kB","bb","yb","zb","eb","pb","tb","gb","mb","kb"})+0)>=1,"LOWERCASE DETECT","CORRECT")

水平：=IF(SUM(EXACT(IFERROR(LEFT(RIGHT(B4:C4,LEN(B4:C4)-SEARCH(" ",B4:C4,1)),2),""),{"Bb","Yb","Zb","Eb","Pb","Tb","Gb","Mb","Kb","bB","yB","zB","eB","pB","tB","gB","mB","kB","bb","yb","zb","eb","pb","tb","gb","mb","kb"})+0)>=1,"LOWERCASE DETECT","CORRECT")

公式返回＃N / A错误。

=IF(SUM({0,0,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A,#N/A})>=1,"LOWERCASE DETECT","CORRECT")

我尝试使用IFNA（）捕获＃N / A，但未成功：

=SUM(IFNA(EXACT(IFERROR(LEFT(RIGHT(B4:C4,LEN(B4:C4)-SEARCH(" ",B4:C4,1)),2),""),{"Bb","Yb","Zb","Eb","Pb","Tb","Gb","Mb","Kb","bB","yB","zB","eB","pB","tB","gB","mB","kB","bb","yb","zb","eb","pb","tb","gb","mb","kb"})+0,0))

公式返回0

=IF(SUM({0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0})>=1,"LOWERCASE DETECT","CORRECT")

再次失败，该公式不计算在内。为什么公式在水平方向上不起作用？

Answer 1

您可以使用以下命令保存一些键入内容：

=IF(SUMPRODUCT(--(NOT(EXACT(UPPER(RIGHT(B4:C4,2)),RIGHT(B4:C4,2))))),"LOWERCASE DETECT","CORRECT")

公式的错误是您创建了一个水平数组，将其与水平数组进行比较，该水平数组必须为相同的数字并进行一对一比较。

您需要转置值数组：

=IF(SUM(EXACT(IFERROR(LEFT(RIGHT(B4:C4,LEN(B4:C4)-SEARCH(" ",B4:C4,1)),2),""),TRANSPOSE({"Bb","Yb","Zb","Eb","Pb","Tb","Gb","Mb","Kb","bB","yB","zB","eB","pB","tB","gB","mB","kB","bb","yb","zb","eb","pb","tb","gb","mb","kb"}))+0)>=1,"LOWERCASE DETECT","CORRECT")
