I'm having a table looking like this:
id1 | id2 | dateUpdate
==========================================
aaa | 111 | 2016-01-01
aaa | 111 | 2016-01-02
aaa | 222 | 2016-01-05
aaa | 222 | 2016-01-15
bbb | 333 | 2016-01-05
bbb | 444 | 2016-01-01
ccc | 111 | 2016-01-02
I'd like to get only the latest row for each id1/id2 couple:
id1 | id2 | dateUpdate
==========================================
aaa | 111 | 2016-01-02
aaa | 222 | 2016-01-15
bbb | 333 | 2016-01-05
bbb | 444 | 2016-01-01
ccc | 111 | 2016-01-02
Thanks for your help!
Use Aggregate Function
=AGGREGATE(14, 6, 1/($A$2:$A$99=E2)*($B$2:$B$99=F2)*($C$2:$C$99), 1)
You have to put the unique combinations in column E2 and Column F2 downwards
You have five unique combinations
COLUMN A COLUMN B
aaa 111
aaa 222
bbb 333
bbb 444
ccc 111
And Aggregate Funtion is to be put in column G2 and fill down downwards.
=AGGREGATE(14, 6, 1/($A$2:$A$99=E2)*($B$2:$B$99=F2)*($C$2:$C$99), 1)
Regarding Syntax 14 is for Large value that is the for example larger for first aaa 111 combination that is #02-01-2016#
Next digit 6 in formula is for ignoring errors
You can quickly get the pseudo-Last value using the AGGREGATE function..
This is a standard non-array formula that does NOT require Ctrl+Shift+Enter. AGGREGATE was introduced with Excel 2010.
($A$2:$A$99=E2) checks which value of column A matches with the first unique value of column A of unique combination of A & B
This is converted to an array of logical values which gives an array of True Or False. Dividing 1 by these logical values give either 1 or DIV# error. Similar process is adopted for Column B values mentioned in column F. I have taken data limited to 99 rows. If it more number of rows you change the figure of 99 to a higher figure as per your requirements.
HTH
EDIT
You can also go for pivot table solution as suggested by #Tim Biegeleisen in his comments. Snapshot given here-under illustrates that approach.
id1 and id2 are taken as filter fields and Maximum Value of dateUpdate is chosen in the value field.

With reference to the answer from this question I wanted to sum up the unique values per product in Cell A1.
Therefore, I tried to go with this formula:
A1 =SUM(INDEX(UNIQUE(IF(SUBTOTAL(2;OFFSET(B2:B9;ROW(B2:B9)-ROW(B2);1;1));A2:B9));;1))
However, as a result now I get 0 instead of 1.900.
I assume the issue results because I have the values on the left side of the criteria column.
Do you have any idea how I need to modify the formula to also make it work in the displayed column order?
All you needed to do was to change the 1 into -1 on the OFFSET():
=SUM(INDEX(UNIQUE(IF(SUBTOTAL(2,OFFSET(B2:B9,ROW(B2:B9)-ROW(B2),-1,1)),A2:B9)),,1))
I have a table as:
(Column A)Company Name | (Column B)Company Number
ABC | 123
ABC |
CBA |
CBA | 234
ACB | 567
ACB |
In Column B I need to insert data in row 2 as row 1 (or vice versa) because row 1 and 2 in Column A have same data. The table i have has about 6M such rows and hence looking for some help.
I think you need filters and then just paste the values you need.
In excel, I have data divided into
Year Code Class Count
2001 RAI01 LNS 9
2001 RAI01 APRP 4
2001 RAI01 3
2002 RAI01 BPR 3
2002 RAI01 BRK 3
2003 RAI01 URE 3
2003 CFCOLLTXFT APRP 2
2003 CFCOLLTXFT BPR 2
2004 CFCOLLTXFT GRL 2
2004 CFCOLLTXFT HDS 2
2005 RAI HDS 2
where I need to find the top 3 products for that particular customer for that particular year.
The real trick here is to rank each row based on a group.
Your rank is determined by your Count column (Column D).
Your group is determined by your Year and Code (I think) columns (Column A and B respectively).
You can use this gnarly sumproduct() formula to get a rank (Starting at 1) based on the Count for each Group.
So to get a ranking for each Year and Code from 1 to whatever, in a new column next to this data:
=SUMPRODUCT(($A$2:$A$50=A2)*(B2=$B$2:$B$50)*(D2<$D$2:$D$50))+1
And copy that down. Now you can AutoFilter on this to show all rows that have a rank less than 4. You can sort this on Customer, then Year and you should have a nice list of top 3 within each year/code.
Explanation of sumproduct.
Sumproduct goes row by row and applies the math that is defined for each row. When it is done it sums the results.
As an example, take the following worksheet:
+---+---+---+
| | A | B |
+---+---+---+
| 1 | 1 | 1 |
| 2 | 1 | 4 |
| 3 | 2 | 2 |
| 4 | 4 | 1 |
| 5 | 1 | 2 |
+---+---+---+
`=SUMPRODUCT((A1:A5)*(B1:B5))`
This sumproduct will take A1*B1, A2*B2, A3*B3, A4*B4, A5*B5 and then add those five results up to give you a number. That is 1 + 4 + 4 + 4 + 1 = 15
It will also work on conditional/boolean statements returning, for each row/condition a 1 or a 0 (for True and False, which is a "Boolean" value).
As an example, take the following worksheet that holds the type of publication in a library and a count:
+---+----------+---+
| | A | B |
+---+----------+---+
| 1 | Book | 1 |
| 2 | Magazine | 4 |
| 3 | Book | 2 |
| 4 | Comic | 1 |
| 5 | Pamphlet | 2 |
+---+----------+---+
=SUMPRODUCT((A1:A5="Book")*(B1:B5))
This will test to see if A1 is "Book" and return a 1 or 0 then multiple that result by whatever is B1. Then continue for each row in the range up to row 5. The result will 1+0+2+0+0 = 3. There are 3 books in the library (it's not a very big library).
For this answer's sumproduct:
So ($A$2:$A$50=A2) says to return a 1 if A2=A2 or a 0 if A2<>A2. It does that for A2 through A50 comparing it to A2, returning a 1 or a 0.
(B2=$B$2:$B$50) will test each cell B2 through B50 to see if it is equal to B2 and return a 1 or 0 for each test.
The same is true for (D2<$D$2:$D$50) but it's testing to see if the count is less than the current cells count.
So... essentially this is saying "For all the rows 1 through 50, test to find all the other rows that have the same value in Column A and B AND have a count less than this rows count. Count all of those rows up that meet that criteria, and add 1 to it. This is the rank of this row within its group."
Copying this formula has it redetermine that rank for each row allowing you to rank and filter.
Hi guys and all Excel gurus, I am stuck with this one excel problem which I cannot solve. I tried using Index, Match, Vlookup but to no avail.
Basically I tried getting Column D displays Value from Column B if the Value of Column C contains part of the value in Column A.
So what I'm dealing with is something kind of like this:
Fixed the table display
+------------------------------------------------------+
| Header Column A Column B Column C Column D |
+------------------------------------------------------+
| Row 1 111 AAA 1111 |
| Row 2 222 BBB 112 |
| Row 3 333 CCC 2225 |
| Row 4 444 DDD 333 |
+------------------------------------------------------+
So my expected result would be:
+------------------------------------------------------+
| Header Column A Column B Column C Column D |
+------------------------------------------------------+
| Row 1 111 AAA 1111 AAA |
| Row 2 222 BBB 112 N/A |
| Row 3 333 CCC 2225 BBB |
| Row 4 444 DDD 333 CCC |
+------------------------------------------------------+
Sorry for the poor table display and explanation. Thanks Guys.
=INDEX($C$2:$C$5, MATCH(1,IF(ISERR(FIND($B$2:$B$5, $D2)),0,1),0))
, where 5 is the last data row. Enter as an array formula (Ctrl+Shift+Enter) in E2, then drag down.
BTW on row 4 it gives CCC, not N/A.
let's call this table1:
|111|222|333|444|555
--------------------
|6 |6 |4 |3 |3
now lets say i have another table, and i need to use the information from both of them,
table2:
111|aaa
222|bbb
333|ccc
444|ddd
555|eee
I want the result table to look like this:
result table:
aaa|6
bbb|6
ccc|4
ddd|3
eee|3
any ideas?
Use a direct reference to get the first column of your results table:
For the second column, use combination of Index, Match, and HLookup functions:
You can use HLOOKUP.
For example, if you first table is in A1:E2 then you can use:
A B C D E
1 111 222 333 444 555
2 6 6 4 3 3
3
4
5 111 aaa =HLOOKUP(A5,$A$1:$E$2,20 //Returns 6
6 222 bbb
7 333 ccc
8 444 ddd
9 555 eee
Just drag down the formula.
