Excel 公式 - 通过匹配源单元格连接多个单元格的标准

Question

I am Looking to concatenates multiple cells into one by Index-matching the criteria

The below formula is not pulling in all the required UPCs against the specified criteria

 =INDEX($B:$B,MATCH($D:$D,$A:$A,0))

I would like the end result to look like COL E2 in the below image with semi-colons in between every value ;

Any help here would be much appreciated.

Answer 1

If you have Office365 then use TEXTJOIN() with FILTER() function.

=TEXTJOIN(";",TRUE,FILTER($B$2:$B$15,$A$2:$A$15=D2))

Edit: Assuming you don't have access to O365 dynamic formulas. Then try below array formula.

=TEXTJOIN(";",TRUE,IF($A$2:$A$15=D2,$B$2:$B$15,""))

Press CTRL + SHIFT + ENTER to evaluate the formula as it is an array formula.

Answer 2

An alternative approach using the CONCAT function:

=CONCAT(FILTER(B:B, A:A=D2)&";")

Explanation:

1. The FILTER logic is just like Harun24HR suggested. Creating an array of all the values in B where the value in A is equal to D2.
2. The & operator works on each element in the array and adds a delimiter ";" to each value.
3. Finally, the CONCAT function combines all of the elements in the array into a single string.
