Excel Match function as array formula serching multiple colums - excel

I've got some problem with this function. I've Tried to find position some cell on the list consisted of two columns. My formula MATCH(A1;D1:E10;0) gives me an #N/D error, but when I change formula for each separate column like e.g. MATCH(A1;D1:D10;0) it works. Is three possibility to do this simultanously for both colums. Maybe some array formula?

Match will not work with 2 dimensional ranges.
You can use AGGREGATE to return the correct ROW:
=AGGREGATE(15,6,ROW(D1:E10)/(D1:E10 = A1),1)

INDEX/MATCH with 4 columns

I have an Excel file with 2 sheets - one sheet contains my items, prices, codes, etc. and the other sheet is for cross-matching with competitors.
I've included an Excel file and image below.
I want to be able to generate my code automatically when manually entering any of my competitor's codes. I was able to do INDEX/MATCH but I was only able to match with one column (I'm assuming they're all in one sheet to make it easier). Here is my formula:
=INDEX(C:C,MATCH(K2,E:E,0)
So this is looking only in E:E, when I tried to enter a different column such as C:C or D:D it returns an error.
I tried to do the MATCH as C:G but it gave an error right away.
The reason why match gave you error is because it's looking for an array and you put in multiple columns.
There is definitely a more elegant way to do this but this is the first one that I came up with.
=IFERROR(INDEX(B:B,MATCH(K2,C:C,0)),IFERROR(INDEX(B:B,MATCH(K2,D:D,0)),IFERROR(INDEX(B:B,MATCH(K2,E:E,0)),IFERROR(INDEX(B:B,MATCH(K2,F:F,0)),IFERROR(INDEX(B:B,MATCH(K2,G:G,0)),"")))))
Index/Match Combination
Please try this formula:
{=INDEX($B$2:$B$5,MATCH(1,(K2=$C$2:$C$5)+(K2=$D$2:$D$5)+(K2=$E$2:$E$5)+(K2=$F$2:$F$5)+(K2=$G$2:$G$5),0))}
Instruction: Paste the formula {without the curly brackets} to the formula bar and hit CTRL+SHIFT+ENTER while the cell is still active. This will create an array formula. Hence, the curly brackets. Please take note though that manually entering the curly brackets will not work.
Description:
The INDEX function returns a value or the reference to a value from within a table or range.1
The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range.2
Syntax:
The INDEX function has two forms—Array and Reference form. We're going use the Reference form in this case.
INDEX(reference, row_num, [column_num], [area_num])1
MATCH(lookup_value, lookup_array, [match_type])2
Explanation:
To simplify, we're going to use this form:
INDEX(reference, MATCH(lookup_value, lookup_array, [match_type]))
The INDEX function returns a value from the reference My code column (B1:B5) based on the row_num argument, which serves as an index number to point to the right cell, and we're going to do that by substituting row_num with MATCH function.
MATCH function, on the other hand, returns the relative position of a value in competitorn column that matches the value in individual cells of the competitor code column.
To make it work with multiple lookup range, we're going to create arrays of boolean values (TRUE/FALSE, aka logical values) by comparing values from individual cells in competitor code column with values in individual competitorn columns. Now, we convert these boolean values into numerical values by performing a mathematical operation that does not alter its implied value (i.e. TRUE=1, FALSE=0). We're going to add these values directly to make it simple. The resulting array have four index with two possible values: 1 or 0. Since each item in MATCH's lookup_array is unique, then there can be only one TRUE or 1. The rest are FALSE or 0's. So, with that knowledge, we're going to use it as our lookup_value.
Let's dissect the formula:
=INDEX(B2:B5,MATCH(1,(K2=C2:C5)+(K2=D2:D5)+(K2=E2:E5)+(K2=F2:F5)+(K2=G2:G5),0))
My code 2 = INDEX({"My code 1";"My code 2";"My code 3";"My code 4"},MATCH)
My code 2 = INDEX({"My code 1";"My code 2";"My code 3";"My code 4"},(2))
2 = MATCH(1,(K2=C2:C5)+(K2=D2:D5)+(K2=E2:E5)+(K2=F2:F5)+(K2=G2:G5),0)
2 =MATCH(1,
{FALSE;FALSE;FALSE;FALSE}+
{FALSE;FALSE;FALSE;FALSE}+
{FALSE;FALSE;FALSE;FALSE}+
{FALSE;FALSE;FALSE;FALSE}+
{FALSE;TRUE;FALSE;FALSE},0))
OR
=MATCH(1,
{0;0;0;0}+
{0;0;0;0}+
{0;0;0;0}+
{0;0;0;0}+
{0;1;0;0},0))
=========
{0;1;0;0},0))
2 = MATCH(1,{0;1;0;0},0))
I hope this answer is helpful.

Create an array formula

My index match formula is returning #N/A and I cannot figure out why?

I am trying to use an index match formula to return a value based on two values. However, it is returning #n/a. I have created a simple table with one row and 3 coloumns as a test to try and figure out what is going wrong. Below is a simple table I made for this purpose. I want to return column L based on the criteria from columns J and K.
J K L
123 4 7
Here is the formula I have used.
=INDEX(L3,MATCH(1,(M8=J3)*(N8=K3),0))
I also used ctrl-shft-enter to run the formula but it is giving me an NA value. When I use an index match to return a value based on only one criteria, the formuala works and it returns a 7 but when I try for multiple criteria, the formula fails.
Any help would be greatly appreciated.
Thanks,
G
I think what you need to do is Concatenate the columns of interest then do the match. Try:
=INDEX(L3,MATCH(M8&N8,J3:J6&K3:K6,0))
This should be entered as array formula using Ctrl+Shift+Enter.
What the formula does is:
Concatenate the values being searched in memory.
=INDEX(L3,MATCH(123&4,J3:J6&K3:K6,0))
Then it also concatenates all the values in the columns joined in memory.
=INDEX(L3,MATCH("1234",{"1234";"";"";""},0))
And then the actual matching.

Returning multiple column headers values using multiple matching criteria

I am looking for returning multiple column values using multiple matching criteria.
Attached is a screenshot of sample sheet, which have my criteria on cell's B1 & C1.
So basically, when matching 2 criteria (example "Team1" & "low"), it should return columns header (example Name10 & name14) from the header ranger C3:N3.
I have tried a couple of formulas, and is is how far I gone: =INDEX($C$2:$AL$2,SMALL(IF(($A$3:$A$21=$B$1)*($B$3:$B$21=$C$1),ROW($A$3:$A$21)-ROW($A$3)+1),ROW(1:1)))
I am not sure what is missing?

First of all, in your example you point out row 3 and 4 but only one of the specified criteria are matched in this rows: low, because Team4 specifyed in the criteria it's not matched, so i will consider you are looking to match one OR both the criteria specified.
The only way i can imagine for do this with a formula is to use a formula like this
=SE(C3<>0;$C$2&", ";"")&SE(D3<>0;$D$2&", ";"")&SE(E3<>0;$E$2&", ";"")&SE(F3<>0;$F$2&", ";"")&SE(G3<>0;$G$2&", ";"")&SE(H3<>0;$H$2&", ";"")&SE(I3<>0;$I$2&", ";"")&SE(J3<>0;$J$2&", ";"") 'and so on...
where SE() it's function IF() in my language, with this formula in a column on the right of the table (for example col O) you will have a list of the names of that row where the corresponding number is different from 0...expand the formula down for all the rows and then, with a formula like this
=SE(O(A1=A3;B1=B3);O3;"")&SE(O(A1=A4;B1=B4);O4;"")&SE(O(A1=A5;B1=B5);O5;"")&SE(O(A1=A6;B1=B6);O6;"")&SE(O(A1=A7;B1=B7);O7;"") 'and so on...
with the function O() corresponding to OR() you will concatenate the strings (names) of the rows that match one OR both the criteria. If you whant to match both the criteria you should use AND() instead of OR().
The problem of this approach is that the formula becomes very long if you have a lot of names and a lot of rows, and if you add rows you have to modify the formula. Another problem is that if you match the same name more times it will be repeated in the list that the formula outputs...and the list of the names ends with a comma.
In fact, i can't tell that this is a good way for obtain what you need, but it's the only i can imagine only with formulas.
If you should use a macro the problem would be solved better and in a more flexible way, should you?

Function to count all rows with multiple criteria

I'm trying to use the COUNTIFS statement to count all rows where values in 4 different columns equal "something", while excluding rows where the values in two columns are equal. This is what I have for counting the rows where the 4 columns equal "something" but I can't figure out how to add the last part:
=COUNTIFS(A2:A100,"something",B2:B100,"something",C2:C100,"something",D2:D100,"something", [...])
Now I need to add another statement within this COUNTIFS at the [...] that says something like "exclude all rows where value in J is equal to value in K", but I can't seem to figure out how to do that WITHIN the COUNTIFS statement.
You likely have to move to a SUMPRODUCT function.
=SUMPRODUCT((A2:A100="something")*(B2:B100="something")*(C2:C100="something")*(D2:D100="something")*(J2:J100<>K2:K100))
Avoid full column references in SUMPRODUCT due to the cyclic nature of the calculation.
You could use an Array function for this.
={sum((A1:A1000 = 'Something')*(BB:B1000 = 'Something')*(C1:C1000 = 'Something')*(D1:D1000 = 'Something')*(J1:J1000 = K1=K1000))}
for entering an array function, you need to use Ctrl+Shift+Enter

VLOOKUP with two criteria?

Is there a formula that returns a value from the first line matching two or more criteria? For example, "return column C from the first line where column A = x AND column B = y". I'd like to do it without concatenating column A and column B.
Thanks.
True = 1, False = 0
D1 returns 0 because 0 * 1 * 8 = 0
D2 returns 9 because 1 * 1 * 9= 9
This should let you change the criteria:
I use INDEX/MATCH for this. Ex:
I have a table of data and want to return the value in column C where the value in column A is "c" and the value in column B is "h".
I would use the following array formula:
=INDEX($C$1:$C$5,MATCH(1,(($A$1:$A$5="c")*($B$1:$B$5="h")),0))
Commit the formula by pressing Ctrl+Shift+Enter
After entering the formula, you can use Excel's formula auditing tools to step through the evaluation to see how it calculates.
SUMPRODUCT definitely has value when the sum over multiple criteria matches is needed. But the way I read your question, you want something like VLOOKUP that returns the first match. Try this:
For your convenience the formula in G2 is as follows -- requires array entry (Ctrl+Shift+Enter)
[edit: I updated the formula here but not in the screen shot]
=INDEX($C$1:$C$6,MATCH(E2&"|"&F2,$A$1:$A$6&"|"&$B$1:$B$6,0))
Two things to note:
SUMPRODUCT won't work if the result type is not numeric
SUMPRODUCT will return the SUM of results matching the criteria, not the first match (as VLOOKUP does)
Apparently you can use the SUMPRODUCT function.
Actually, I think what he is asking is typical multiple results display option in excel. It can be done using Small, and row function in arrays.
This display all the results that matches the different criteria
Here is an answer that shows how to do this using SUMPRODUCT and table header lookups. The main advantage to this: it works with any value, numeric or otherwise.
So let's say we have headers H1, H2 and H3 on some table called MyTable. And let's say we are entering this into row 1, possibly on another sheet. And we want to match H1, H2 to x, y on that sheet, respectively, while returning the matching value in H3. Then the formula would be as follows:
=INDEX(MyTable[H3], ROUND(SUMPRODUCT(MATCH(TRUE, (MyTable[H1] & MyTable[H2]) = ($x1 & $y1),0)),0),1)
What does it do? The sum-product ensures everything is treated as arrays. So you can contatenate entire table columns together to make an array of concatenated valued, dynamically calculated. And then you can compare these to the existing values in x and y- somehow magically you can compare the concatenated array from the table to the individual concatenation of x & y. Which gives you an array of true false values. Matching that to true yields the first match of the lookup. And then all we need to do is go back and index that in the original table.
Notes
The rounding is just in there to make sure the Index function gets back an integer. I got #N/A values until I rounded.
It might be more instructive to run this through the evaluator to see what's going on...
This can easily be modified to work with a non table - just replace the table references with raw ranges. The tables are clearer though, so use them if possible. I found the original source for this here: http://dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/. But there was a bug with rouding values to INTs so I fixed that.
