我在列中有值:
08FHI800
08FHI800
08FHI800
07FJM933
07FJM933
89MNA900
我需要一个公式,告诉我列中有多少项具有相应的重复项。在这种情况下,它将是2.
答案 0 :(得分:2)
尝试此公式,假设数据为A2:A100
=SUMPRODUCT((A2:A100<>"")/COUNTIF(A2:A100,A2:A100&"")-(COUNTIF(A2:A100,A2:A100&"")=1))
它将忽略空白
答案 1 :(得分:0)
=SUMPRODUCT((A1:A12<>"")/COUNTIF(A1:A12,A1:A12&"")-(COUNTIF(A1:A12,A1:A12&"")=1))
以这些数据为例
Row# ColA
1 1
2 2
3 2
4 2
5 3
6 4
7 5
8 5
9 6
10 6
11 6
12 7
将功能分为3个部分:
(A1:A12<>””)
COUNTIF(A1:A12,A1:A12&””)
COUNTIF(A1:A12,A1:A12&””)=1
组件1
(A1:A12<>””) evaluates to an array containing {T, T, T, T, T, T, T, T, T, T, T, T} ---------(1)
组件2
COUNTIF(A1:A12,A1:A12&””)
评估为
COUNTIF({1,2,2,2,3,4,5,5,6,6,6,7},{1,2,2,2,3,4,5,5,6,6,6,7}
,它计算每个值出现在范围内的次数 反过来,求值结果为:
{1,3,3,3,1,1,2,2,3,3,3,1} -----------------(2)
(“&”是为了避免#DIV / 0错误)
现在,由于括号的原因,我们需要在查看组件3之前先评估(组件1 /组件2)。
组件1 /组件2是
(A1:A12<>"")/COUNTIF(A1:A12,A1:A12&"")
从(1)和(2)开始,
{T,T,T,T,T,T,T,T,T,T,T,T}/{1,3,3,3,1,1,2,2,3,3,3,1}
计算结果为:
{1,0.3333,0.3333,0.3333,1,1,0.5,0.5,0.333,0.333,0.333,1}
现在我们可以看看 组件3
COUNTIF(A1:A12,A1:A12&””)=1
我们已经有了第一篇:
COUNTIF(A1:A12,A1:A12&””)
来自(2),其计算结果为
{1,3,3,3,1,1,2,2,3,3,3,1}
将此与= 1结合起来
COUNTIF(A1:A12,A1:A12&””)=1
反过来求值为
{T,F,F,F,T,T,F,F,F,F,F,T}
所以,最终将所有这些结合在一起,我们有了
SUMPRODUCT({1,0.3333,0.3333,0.3333,1,1,0.5,0.5,0.333,0.333,0.333,1} - {T,F,F,F,T,T,F,F,F,F,F,T})
现在,T等于1,F等于0,所以现在变成:
SUMPRODUCT({1-1,0.333-0, 0.333-0, 0.333-0,1-1,1-1,0.5-0,0.5-0, 0.333-0, 0.333-0, 0.333-0,1-1}
成为
SUMPRODUCT({0,0.333,0.333,0.333,0,0,0.5,0.5,0.333,0.333,0.333,0}
因为只有一个数组,所以SUMPRODUCT只是对元素求和
1+1+1 =3
有3个重复的项目。
