在 Excel 数组公式结果中查找匹配项

Question

I am looking for a way do some kind of nested/indirect lookup.

1. I have a table of two columns with car models (eg Mustang) in column A and their makes (eg Ford) in column B
2. In column FI have a list of car models. This can be models that are listed in column A, but not all models of column A have te be listed in F
3. Column D contains some car makes.

For each car make in column DI need to determine whether there exists a model that is present in column F. So with the car make in a of D, I want to look up the corresponding care models in column B and next I want to look for occurrences of these found care models in column F.

I succeed to do the first lookup using an array formula, however I am stuck on how to determine whether the resulting array and the range in F have common elements (or a non-empty intersection).

Any help will be appreciated!

A(Model) B(Make) C(empty) D(=Make2) E(=Found) F(=carlist)

Corvette Chevrolet Dodge (1)? Corvette
Camaro Chevrolet Chevrolet (2)? Mustang
Mondeo Ford Camaro
Mustang Ford
Challenger Dodge
Avenger Dodge

In the example above, on (1) the result should be N, because there are care no models in column F of the make D1 ("Dodge"). On (2) the result should be Y, because there are models (even 2) in column F of the make D2 ("Chevrolet").

I have the following array-formula gets all models for the Make "Dodge" in D1:

{=IFERROR(INDEX($A$1:$A$6; SMALL(IF(D1=$B$1:$B$6; ROW($A$1:$A$6);""); ROW()));"")}

How can I compare the result of this array-formula with matches in column F?

Answer 1

You can enter the following in E3 and drag down. Enter formula with Ctrl + Shift + Enter ie as an array formula.

 =IF(SUMPRODUCT(--ISNUMBER(MATCH($F$3:$F$5,IF(ISNUMBER(SEARCH($D3,$B$3:$B$8)),$A$3:$A$8,""),0)))>0,"Y","N")

Answer 2

If you don't want to lookup the make into column G, you can use this formula:

=IF(0<SUM(MMULT(--(TRANSPOSE($A$2:$A$7)=$F$2:$F$3),--($B$2:$B$7=$D2))),"Y","N")

But I would recommend to create a Make2 column in G, that would be much easier to understand later.

Another option.

Use your current array formula and nest it in a COUNTIF and an IF statement.

{=IF(COUNTIF($F$1:$F$3;IFERROR(INDEX($A$1:$A$6; SMALL(IF(D1=$B$1:$B$6; ROW($A$1:$A$6);""); ROW()));""))>0;"Y";"N")}

---

COUNTIF counts how many times your original formula find any value in carlist.

COUNTIF($F$1:$F$3;IFERROR(INDEX($A$1:$A$6; SMALL(IF(D1=$B$1:$B$6; ROW($A$1:$A$6);""); ROW()));""))>0

If the finding is greater than 0 (at least one match is found) then return yes by the IF formula:

IF(logic expression>0; "Y"; "N").
