EXACT 函数在数组公式中返回“#N/A”错误？

Question

当我将公式应用于 B3:B7 范围时，它可以完美运行。当我将公式应用于 B4:C4 范围时，它不能完美地工作。该公式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")

横向：=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，公式不计算在内。为什么公式在水平方向不起作用？

Answer 1

你可以节省一些打字：

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

您的公式的错误在于您创建了一个水平数组，将其与水平数组进行比较，这需要相同的数字并进行一对一的比较。

你需要转置数组的值：

=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")
