I have array of numbers in a single column like this:
I want only that numbers for which corresponding negative numbers exist. If number exist 2 times, but negative number exist only one time, then I wanted to retain one positive and one negative number. Similarly, if number exists 3 times, and negative number appears only two times, then I want 2 set of numbers including positive and negative. In this case, I wanted to get output:
5 2 -2 -5
Orders of numbers are not relevant for me. Please do not use VBA. You can create multiple column and apply filter at the end.
Thank you for the response, but I wanted to get the data in column next to the values. Like:
5
2
-2
-5
Please help.
Here's another Office 365 solution:
Name the data range DATA
Put this formula anywhere: =CONCAT(REPT(-ROW(A1:A100)&" "&ROW(A1:A100)&" ",COUNTIF(DATA,"="&ROW(A1:A100)*IF(COUNTIF(DATA,"="&-ROW(A1:A100))<COUNTIF(DATA,"="&ROW(A1:A100)),-1,1))))
That will output the pairs into one cell.
Here's a slightly modified Step 2, which excludes duplicates: =CONCAT(IF((COUNTIF(DATA,"="&-ROW(A1:A100))>0)*(COUNTIF(DATA,"="&ROW(A1:A100))>0),-ROW(A1:A100)&" "&ROW(A1:A100)&" ",""))
Looks like this:
The data doesn't need to be sorted. Both methods work up to 100, but you can easily expand that by changing A100 to A1000 or whatever you need.
Use the vlookup formula to identify the rows, and you can use the Filter & Unique formula to get the list, or a pivot table.
First, immediately next to your data use the formula:
=vlookup(A1*-1,$A$1:$A$1,1,0)
For non-365:
This will produce an error for each instance that doesn't have a match. You can filter at this point to get your list from the existing table. You can also create a pivot table under the Data tab of your ribbon and inserting a pivot table. Filter the #N/A from there to get an exclusive list without hidden rows.
For 365:
You can use the following combination of formulas to get the exclusive list as well.
=UNIQUE(FILTER(B1:B8,ISNUMBER(B1:B8)),0,0) or =UNIQUE(FILTER($B$1:$B$8,ISNUMBER($B$1:$B$8)),0,0) should yield the same results
As ScottCraner mentioned, you can circumvent the helper column in 365 by modifying the formula a bit more:
=UNIQUE(FILTER(A1:A8,ISNUMBER(MATCH(-A1:A8,A1:A8,0)),"")
The Match here is doing something similar to the Vlookup, but housing that logic within the formula, so it's a cleaner solution in my opinion.
Using your data the result was { -5,-2,2,5 }
These are spill formulas so you only need to put it in one spot and it will expand the formula over the adjacent cells below where it's entered for however many cells needed to list all the unique numbers that occur. It takes into account the negatives and so on. This may be a 365 formula, so if you're on another version of excel it may not work.
Edit: Adjusted the instructions to fully address the question.

I need help in writing a formula in cell b7. The formula must look to the right and multiply the nonempty cells by the corresponding value in row 3, and I would like to sum up the results.

Please see my comment to your original post.
That said, I will try to explain how to approach this as I think you intend. (This solution will be a Google Sheets solution which will not work in Excel.)
The first thing you will need to do is to delete everything from Row 11 down: all of your examples and notes must be deleted for the following proposed formula to work correctly.
Once you have no superfluous data below your main chart, delete everything from B6:B (including the header "Total").
Then, place the following formula in cell B6:
={"TOTAL"; FILTER(MMULT(C7:G*1, TRANSPOSE(C$3:G$3*1)), A7:A<>"")}
This formula will return the header text "TOTAL" (which you can change within the formula itself if you like) followed by the calculation you want for each row where a name is listed in A7:A.
MMULT is a difficult function to explain, but it multiplies one matrix ("grid") or numbers by another matrix ("grid") and returns the sum of all products per row (or per column, depending on how you set it up) —— which is what you are trying to do.
MMULT must have every element of both matrices be a real number. To convert potential nulls to zeroes, you'll see *1 appended to each range (since null times 1 is zero).
This assumes that all data entered into C7:G and C3:G3 will always be either a number or null. If you enter text, you'll throw the formula into an error. If you think accidental text entries in those ranges are possible, use this version instead:
={"TOTAL"; FILTER(MMULT(IFERROR(C7:G*1, ROW(C7:G)*0), TRANSPOSE(IFERROR(C$3:G$3*1, COLUMN(C$3:G$3)*0))), A7:A<>"")}
The extra bits use IFERROR to exchange error-producing entries with zeroes, since MMULT must have every space in both matrices filled with a real number.
I have two lists, the first is a set of users. The second list contains different encounter dates for these users.
I need to identify the date that is within 10 days of the "Renew Date" [Column C], but not before. With Member 1 this would be row 3 1/8/2017. With Member 2 this would be row 6, 1/21/2017.
Now using a VLOOKUP which the user before me who managed this spreadsheet obviously isn't viable as it's simply going to pickup the first date that has a matching Member ID. Is there a way to do this in Excel at all?
I have included a link to a sample file and a screenshoit of the sample data.

To avoid the slowness and complexities of array formulas, you can try with SUMIFS but the problem is that if you have more than one match, it will add them, not return the first match. The sum will look like an aberration. Will work however if you are guaranateed that you have only one match in the data.
An alternative is also to use AVERAGEIFS, which, in case of multiple matches, will give you their average and it will look like a valid date and a good result. Enter this formula in D2 and fill down the column:
D2:
=AVERAGEIFS(G:G,F:F,A2,G:G,">="&C2,G:G,"<="&C2+10)
and don't forget to format column D as Date.
Try this
=SUMPRODUCT($G$2:$G$7,--($F$2:$F$7=A2),--($G$2:$G$7<=C2+10),--($G$2:$G$7>C2))
Format the result as date. See screenshot (my system uses DMY order)
Don't use whole column references with this formula. It will slow down the workbook.
So I am trying to create a spreadsheet at allows a character in game to total the party inventory.
I am trying to sumif multiple columns based on the same criteria.
So say I am trying to sum all the rope they have.
In column A is the Item descriptions
In columns B-E are the different totals for each party member (one column per person)
Each party member has 50 rope, so I am expecting 200 rope.
I have used this formula:
=SUMIF(A:A,"Rope: Hemp",B:E) and it is only returning 50 as a value, If I utilise cell values (A1:A100 etc.) it returns a value of Zero.
I have been told that Sum Product could works so I also tried that:
=SUMPRODUCT((A1:A100="Rope: Hemp")*(B3:E100)) and I still get the incorrect result.
What am I doing wrong?
EDIT:
Here are some photos.
Here is my Raw Data. As you can see I have the inventory and tallies, when you look at rope it says 150, and this was calcualted by summing the B to E cells, however as the list is going to move and grow I thought SUMIF would be better.
As stated above, I have used a SUMIF making the range Columns B through E, and it only returns a value of 50 (I'm assuming Column B)
so came up with this:
=SUMIF(A3:A40,"="&J17&"",B3:B40)+SUMIF(A3:A40,"="&J17&"",C3:C40)+SUMIF(A3:A40,"="&J17&"",D3:D40)+SUMIF(A3:A40,"="&J17&"",E3:E40)
Which works, but I can only assume that sumif only work with ONE target range... And I tried curly brackets as well...
So, I did also use cell J17 for the object you are looking for, so you can drag it down, the "*" will find all occurences of "Rope: Hemp", or "Rope: Nylon" etc. I get a total of 150 as there are only 3 characters with rope...
Hope it helps. Someone else may have a better / neater suggestion!
I just tested it by entering Rope, rapier and rations into J17 and got the results I expect.
Image of spreadsheet:
I have a (large) array of data in Excel of which I need to compute the average value of certain values in one column, based on the values of another column. For example, here's a snippet of my data:
So specifically, I want to take the average of the F635 mean values corresponding with Row values of 1. To take it a step further, I want this to continue to Row values of 2, Row values of 3 etc.
I'm not familiar with how to run code in Excel but have attempted to solve this by using the following:
=IF($C = "1", AVERAGE($D:$D), "")
which (to my understanding) can be interpreted as "if the values (anywhere) in column C are equal to 1, then take the average of the corresponding values in column D."
Of course, as I try this I get a formula error from Excel.
Any guidance would be incredibly appreciated. Thanks in advance.
For more complicated cases, I would use an array-formula. This one is simple enough for the AVERAGEIF formula. For instance =AVERAGEIF(A1:A23;1;B1:B23)
Array-formula allows for more elaborate ifs. To replicate the above, you could do =SUM(IF($A$1:$A$23=1;$B$1:$B$23;0))/COUNT(IF($A$1:$A$23=1;$B$1:$B$23;0)).
Looks like more work but you can create extremely elaborate if-statements. Instead of hitting ENTER, do CTRL-ENTER when entering the formula. Use * between criteria to replicate AND or + for OR. Example: SUM(IF(($A$1:$A$23="apple")*($B$1:$B$23="green");$C$1:$C$23;0)) tallies values for green apples in c1:c23.
Your sample data includes three columns with potential ifs so my guess is that you're going to need array formulas at some point.
Excel already has a builtin function for exactly this use; AVERAGEIF().
=AVERAGEIF(C:C,1,D:D)
I'm working on data from a population of people with allergies. Each person has a unique ExceptionID, and each allergen has a unique AllergenID (451 in total).
I have a data table with 2 columns (ExceptionID and AllergenID), where each person's allergies are listed row by row. This means that the ExceptionID column has repeated values for people with multiple allergies, and the AllergenID column has repeated values for the different people who have that allergy.
I am trying to count how many times each pair of allergies is present in this population (e.g. Allergen#107 & Allergen#108, Allergen#107 & Allergen#109,etc). To keep it simple I've created a matrix of 451 rows X 451 columns, representing every pair (twice actually because A/B and B/A are equivalent).
I somehow need to use the row name (allergenID) to lookup the ExceptionID in my data table, and count the cases where that matches the ExceptionIDs from the column name (also AllergenID). I have no problem using Vlookup or Index/Match, but I'm struggling with the correct combination of a lookup and Sumproduct or Countif formula.
Any help is greatly appreciated!

PS I'm using Excel 2016 if that changes anything.

So the methods suggested by Dirk and MacroMarc both worked, though I couldn't apply the latter to my full data set (17,000+ rows) because it was taking a long time.
I've since decided to turn this into a VBA macro because we now want to see the counts of triplets instead of pairs.
With the 2 columns you start with, it is as good as impossible... You would need to check every ExceptionID to have 2 different specific AllergenID. Better use a helper-table with ExceptionID as rows and AllergenID as columns (or the opposite... whatever you like). The helper table needs a formula like:
=COUNTIFS($A:$A,$D2,$B:$B,E$1)
Which then can be auto-filled. (The ranges are from my example, you need to change them to your needs).
With this helper-matrix you can easily go for your bigger matrix like this:
=COUNTIFS(E:E,1,INDEX($E:$G,,MATCH($I2,$E$1:$G$1,0)),1)
Again, you can auto-fill with this formula, but you need to change it, so it fits your needs.
Because the columns have the same ID2 (would be your AllergenID), there is no need to lookup them because E:E changes automatically with the auto-fill.
Most important part of the formulas are the $ which should not be messed up, or you can not auto-fill it.
Picture of my self-made example (formulas are from the upper left cell in each table):
If you still have any questions, just ask :)
It can be done straight from your original set-up with array formulas:
Please note that array formulas MUST be entered with Ctrl-Shift-Enter, before copying across and down:
In the example pic, I have NAMED the data ranges $A$2:$A$21 as 'People' and $B$2:$B$21 as 'Allergens' to make it a nicer set-up. You can see in the formula bar how that looks as a formula. However you could use the standard references like this in your first matrix cell:
EDIT: silly me, N function is not needed to turn the booleans into 1's and 0's, since multiplying booleans will do the trick. Below formula works...
SUM(IF(MATCH($A$2:$A$21,$A$2:$A$21,0)=ROW($A$2:$A$21)-1, NOT(ISERROR(MATCH($A$2:$A$21&$E2,$A$2:$A$21&$B$2:$B$21,0)))*NOT(ISERROR(MATCH($A$2:$A$21&F$1, $A$2:$A$21&$B$2:$B$21,0))), 0))
Then copy from F2 across and down. It can be perhaps improved in technique with sumproduct or whatever, but it's just a rough example of the technique....
