I have a list of people who belong to two groups (A or B). I want to create a column which lists all the people who belong to group A.
I have been trying to come up with an array formula but I do not have a working example. Any help appreciated!
Names | Group | Desired Output
Bob | A | Bob
Fred | B | Eric
Matt | B | Dave
Eric | A | Fred
Dave | A |
Stew | B |
Fred | A |
Many Thanks in advance
Normal formula for column C:
C2=
=IFERROR(INDEX(A:A,AGGREGATE(15,6,ROW(B:B)/(B:B="A"),ROW()-1)), "")
Copy/paste down in column C for a sufficient number of cells.
Array formula: select a sufficient number of cells in column C and write the same formula in the formula bar then press Ctrl+Shift+Enter
From this
+---+-------+-------+
| | A | B |
+---+-------+-------+
| 1 | Name | Group |
| 2 | Nick | A |
| 3 | Marc | A |
| 4 | Manny | B |
| 5 | Luck | A |
+---+-------+-------+
you can create two pivot tables with Name in the row label and Group in the filter data.
Then you can filter only people depending on the group.
+---+-------------------+---+
| | A | B |
+---+-------------------+---+
| 1 | Group | A |
| 2 | | |
| 3 | Etichette di riga | |
| 4 | Luck | |
| 5 | Marc | |
| 6 | Nick | |
+---+-------------------+---+
So if your data is in range A1:B7 this would be the formula:
=IFERROR(INDEX($A$1:$A$7,SMALL(IF($B$1:$B$7="A",ROW($A$1:$A$7)-ROW($A$1)+1),ROWS($A$1:A1))),"")
This is array formula that is applied with Ctrl + Shift + Enter and you will need to drag it down.

I am trying to create a list of names that repeat a specific number of times, based on another variable. Basically, if I have the following:
Column A Column B
Amy 5
John 2
Carl 3
the result would be:
Amy
Amy
Amy
Amy
Amy
Carl
Carl
Carl
John
John
I have built the initial list using the Index-Small-Countif, method, to get an alphabetical and distinct list, and then another formula to determine how many times each item repeats. I know I need to use some sort of index/offset with reference to rows, but just can't quite get it to work out.
The list is dynamic and changes daily, so manually retyping the list each day would result in too much human error and time (list is about 50 distinct items, with total number of rows at the end being around 400). Ultimately, the list will be used for a number of sumproduct/vlookups.
I can do this fairly quickly in VBA, but the users of this document don't always trust VBA and trying to get them to Enable Macros each time is not something that is going to work.
Thank you very much for any help you can offer!
Based on your table:
+---+------+---+
| | A | B |
+---+------+---+
| 1 | Amy | 5 |
| 2 | John | 2 |
| 3 | Carl | 3 |
+---+------+---+
In column C stick a "0" at C4 and formula =B1+C2 copying down to just before the 0:
+---+------+---+----+
| | A | B | C |
+---+------+---+----+
| 1 | Amy | 5 | 10 |
| 2 | John | 2 | 5 |
| 3 | Carl | 3 | 3 |
| 4 | | | 0 |
+---+------+---+----+
Now we have an upper bound of the row that each value should be placed on which we can use in a Match() formula which will feed an Index() formula.
In a new column (I'm using E) IN E1: =INDEX($A$1:$A$3,MATCH(ROW(),$C$1:$C$3,-1),1) and copy down
+----+------+---+----+--+------+
| | A | B | C | D | E |
+----+------+---+----+--+------+
| 1 | Amy | 5 | 10 | | Carl |
| 2 | John | 2 | 5 | | Carl |
| 3 | Carl | 3 | 3 | | Carl |
| 4 | | | 0 | | John |
| 5 | | | | | John |
| 6 | | | | | Amy |
| 7 | | | | | Amy |
| 8 | | | | | Amy |
| 9 | | | | | Amy |
| 10 | | | | | Amy |
+----+------+---+----+--+------+
The list is backwards because of that oddball backwards from 0 thing we did in Column C. This is to make that Match() last parameter of -1 (Greater than) work correctly.
I would imagine with some tweaking this could be done a little cleaner, but this should get you in the ballpark.
Although I would still be a big proponent of finding users who are capable of enabling macros. Ugh.
I have an Excel column that cannot be sorted and for which I need to create a unique id by group, similar to what is below:
+--------+------+
| Name | ID |
+--------+------+
| Jim | 1 |
| Sarah | 1 |
| Tim | 1 |
| Jim | 2 |
| Rachel | 1 |
| Sarah | 2 |
| Jim | 3 |
| Sarah | 3 |
| Rachel | 2 |
| Tim | 2 |
+--------+------+
You can do this with a simple COUNTIF() and getting a little creative with your cell references:
=COUNTIF($A$1:$A1, A2) + 1
Put that in B2 (assuming your list with headers starts in A1) and then copy down.
COUNTIF() here is counting the number of times the name in the adjacent cell has appears in all of the cells above it. As you copy it down, that range will grow to include all cells between A1 and the next row up.
In MS Excel, I want to count the number of distinct categories (ignoring a specific item) based on a different column. Also, I want to find the average and the max for the same selection. This is the data:
+--------+-----------+-------+
| Person | idea | score |
+--------+-----------+-------+
| George | vacuum | 9 |
| George | box | 6 |
| George | x | 1 |
| Joe | scoop | 4 |
| Joe | x | 1 |
| Joe | x | 1 |
| Joe | scoop | 4 |
| Joe | gear | 7 |
| Mike | harvester | 10 |
| Mike | gear | 7 |
| Mike | box | 6 |
+--------+-----------+-------+
The result should be the following:
+--------+----------------+------------+-----------+
| Person | distinct ideas | Avg. score | Max score |
+--------+----------------+------------+-----------+
| George | 2 | 5.3 | 9 |
| Joe | 2 | 3.4 | 7 |
| Mike | 3 | 7.7 | 10 |
+--------+----------------+------------+-----------+
Because Joe has two "scoop" and one "gear" idea, and I want to ignore the "x" items.
I reluctantly gave up and did it manually for each person, e.g., this is for the first person:
SUM(IF(FREQUENCY(MATCH(B2:B4,B2:B4,0),MATCH(B2:B4,B2:B4,0))>0,1))-IF(COUNTIF(B2:B4,"x")>0,1,0)
Doesn't Excel have functions to return a range instead of a value? If I could select the range based on the name of the person in the first columns, I could count distinct occurrences or find the average in another column.
Add a 4th column and label it Distinct Ideas
If your table starts in A1, then:
EDIT: Formula changed to exclude "x". Screen shot also changed
D2: =IF(TRIM($B2)="x",0,IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2))>1,0,1))
and fill down.
Then construct a Pivot table
Person to Row Labels
Distinct Ideas to Values area
score to Values and select to Average
Score to Values area and Select Max
Format as desired. Here is one result:

Any ideas? Is it possible without VBA macro?
I believe that the following link on removing duplicates from column would suit your needs (in your case you would do it horizontally).
http://www.get-digital-help.com/2009/03/30/how-to-extract-a-unique-list-and-the-duplicates-in-excel-from-one-column/
Per your reply to Robert, if you want to do it without VBA, try this... Select all cells in the first column. Copy and paste them into the first column of another worksheet. Use Excel's Remove Duplicates function on the pasted data. Then use INDEX functions in the columns to the right in order to pull the first, second, etc values matching that first column value.
I have two columns of data with an hundred names on and I need to find the matches.
The problem is when names on the second column are not exactly the same as the first column. Its hard to match them with a hundred names.
Is there any formula in excel for at least give tolerance with the data like "Setyadi" with "Setiadi", or "Tak Jelan" with "Tak Lejan".
Thanks for the solution, it works, I edited this because I want to ask more,
I have another problem, could you help me again?
I have a data like this, I want to fill column C with a number according to match the name in column D with column A. The other problem is, I want to match the name that only in a group that mentioned in column E, even not in the same row.
From
A | B | c | D | E |
Setyadi | 1 | | Setiadi | 11 |
Tak Jelan | 2 | | Tak Lejan | 11 |
Gordon | 3 | | Herik | 12 |
Alex | 4 | | Goerdon | 12 |
Heri | 5 | | Alex | 12 |
Into
A | B | c | D | E |
Setyadi | 1 | 1 | Setiadi | 11 |
Tak Jelan | 2 | 2 | Tak Lejan | 11 |
Gordon | 3 | 5 | Herik | 12 |
Alex | 4 | 3 | Goerdon | 12 |
Heri | 5 | 4 | Alex | 12 |
What I need is, how can we compare the name in group that mentioned in column D, then We can automatically give the number in column C that coupling from column B.
Thanks in advance
You can use something like John Walkenbach's SOUNDEX() function:
http://spreadsheetpage.com/index.php/tip/searching_using_soundex_codes/
Then put the code in Excel:
http://www.contextures.com/xlvba01.html
Now, if you had this data:
A | B
Setyadi | Setiadi
Tak Jelan | Tak Lejan
Now you want to add a formula in C1 like:
=SOUNDEX(A1)
And copy that formula to C2, D1, and D2.
Now take a look at your data:
A | B | SOUNDEX(ColumnA) | SOUNDEX(ColumnB)
Setyadi | Setiadi | S330 | S330
Tak Jelan | Tak Lejan | T245 | T242
Notice how Setyadi and Setiadi are exactly the same, that's because they sound the same, which is why the code from the SOUNDEX function comes back like this.
Now when you look at the Tak Jelan entry, you see that there is a difference of 3 (from T245 to T242). Now, what I would do is creat a new formula where if the first letter is the same, then pull out only the number and compare how close they are like:
=IF(LEFT(C1,1)=LEFT(D1,1),STDEV.P(MID(C1,2,3),MID(D1,2,3)))
Then you can compare the std deviation.
