I have an Excel sheet:
A. B. C.
X. I. 10/10/2018 06:27:54
X. I. 12/10/2018 13:00:00
X. U. 12/10/2018 13:01:20
Y. I. 13/10/2018 13:05:40
Y. U 15/10/2018 07:22:23
Y. U. 17/10/2018 08:20:43
Column A is customer, Column B is activity, C is Start time.
How can get the maximum value (column C) of activity I for customer X?
using a standard formula that performs array like calculations
AGGREGATE
Use the following formula. Since it performs array like calculations, avoid using full column references like F:F as it can lead to a lot of unnecessary calculations.
=AGGREGATE(14,6,C1:C6/((A1:A6="X")*(B1:B6="I")),1)
Instead of hard coding your search values, you can set up the formula to search based on values in other cells. I used the following formula in the example below:
=AGGREGATE(14,6,C1:C6/((A1:A6=$E2)*(B1:B6=$F2)),1)
This answer assumes that your date time in column C is stored as number. If it is stored as a string it will need a modification to the formula in order to convert it to a numerical date for excel.
No need for complex AGGREGATEs or nasty array formulas.
A nice, simple MAXIFS will do what you want:
=MAXIFS($C$2:$C$7,$A$2:$A$7,$E$2,$B$2:$B$7,$F$2)
I would do this with an array formula (ctrl+shift+enter) :
=MAX((--(A1:A6="X."))*(--(B1:B6="I."))*(C1:C6))
Explanation:
the (A1:A6="X.") results in an array with TRUE/FALSE values where the condition is met;
the -- converts this in 1/0
the first * (array multiplication) gives an array with 1/0 where both conditions are met;
the second * gives an array with all values from column C that corresponds with the rows where both conditions are met;
the MAX results then in the maximum.
Just a tricky part with the dot behind the X and I. Not sure whether this is part of your data, if not you of course have to modify the condition. And instead of hard coding it in the formula, much better to work with cell reference.

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.
I have a series of data. That goes down the left side column of dates...
8/2, 8/3, and such. Then 2 columns over I have a column left for if the date is checks so 8/2:X, 8/3:X, 8/4: ,8/5: and such. I'm wanting to reference the date in the last field that has a X in it
A B C D
8/1 X
8/2 X
8/3 x
8/4
8/5
Trying to reference the date for the last A cell if there is an X in the D cell. So it would be for 8/3 would be the date. I'm not sure how to run with this.
I've looked through but now sure how to state an if statement
To return the date in column A that is in the same row as the last "X" (or "x") in column D:
=LOOKUP(2,1/(D:D="X"),A:A)
If you only want you cells to calculate if there's an X in column E you could write it like this:
=if(E3="x","", [put your calculation here] )
If you only care if there's anything there, not necessarily an "x" or if you're worried about case sensitivity:
=if(isblank(E3),"", [put your calculation here] )
Then just drag this formula down.
Based on what you had told me use the following formula in cell H1:
=maxifs($A$3:$A$24,$E$3:$E$24,"x")
If I understood correctly, you want to return the highest date with a X in it right? You can simulate a MAX IF with array formulas:
{=MAX(IF(E:E="X",A:A,FALSE))}
(You have to enter the formula with CTRL + SHIFT + ENTER to get those brackets and to it work properly)
The IF part inside that formula returns only a list of values (inside the TRUE part) that the condition returns true
Edit: If you're using Excel 2013 and above, you should check #Mark answer, as it is a cleaner way to do it
Just going to throw my hat in the ring here for a formula that will display the value of date that corresponds to the largest row number with an X in it in column D.
AGGREGATE will find the row number as follows:
=AGGREGATE(14,6,ROW(D:D)/(D:D="x"),1)
That can be nested inside an INDEX function to return the cell address of corresponding date which in turns display the value of the cell as follows:
=INDEX(A:A,AGGREGATE(14,6,ROW(D:D)/(D:D="x"),1))
While the above does work, AGGREGATE is performing array operations. Therefore full column references like D:D should be avoided and reduced to a smaller range that would closer match your data in order to avoid excess calculations on blank cells.
If you can ONLY enter the X consecutively without skipping a date, for instance you would not mark 8/6 X if 8/5 has no X marked, then you can find the last date using the following formula:
=INDEX(Column_Date,COUNTIF(Column_X,"X"))
The look up is case insensitive which means you can also enter lowercase x instead of uppercase X in column D or mix them up, the formula will return the same result anyway.
The solution is using COUNTIF function to locate the position of the last X in Column E of your worksheet, and then use INDEX function to return the corresponding date in Column A.
COUNTIF is a combination of COUNT and IF function. I guess this might be the "IF" function you are after.
Please note if the X is not marked consecutively day by day, you may need to use someone else' answer.
Cheers :)
The blue columns is the data given and the red columns is what is being calculated. Then the table to the right is what I am referencing. So, F2 will be calculated by the following steps:
Look at the Machinery column (D), if the cell contains LF, select column K, otherwise select column L
Look at the Grade column (E), if the cell contains RG, select rows 4:8, otherwise select rows 9:12.
Look at the Species column (A), if the cell contains MS, select rows 5 and 10, otherwise.......
Where every the most selected cell is in columns K and L, copy into column F.
Multiply column F by column C.
I don't want to make another column for my final result. I did in the picture to show the two steps separately. So column F should be the final answer (F2 = 107.33). The reference table can be formatted differently as well.
At first, I tried using nested-if statements, but realized that I would have like 20+ if statements for all the different outcomes. I think I would want to use the SEARCH function to find weather of not the cell contains a specific piece of information. Then I would probably use some sort of combination of match, if, v-lookup, index, search, but I am not sure how to condense these.
Any suggestion?
SUMPRODUCT is the function you need. I quickly created some test data on the lines of what you shared like this:
Then I entered the below formula in cell F2
=SUMPRODUCT(($I$4:$I$9=E2)*($J$4:$J$9=LEFT(A2,FIND(" ",A2)-1))*IF(ISERROR(FIND("LF",D2,1)),$L$4:$L$9,$K$4:$K$9))
The formula may look a little scary but is indeed very simple as each sub formula checks for a condition that you would want to evaluate. So, for example,
($I$4:$I$9=E2)
is looking for rows that match GRADE of the current row in range $I$4:$I$9 and so on. The * ensures that the arrays thus returned are multiplied and only the value where all conditions are true remains.
Since some of your conditions require looking for partial content like in Species and Machine, I have used Left and Find functions within Sumproduct
This formula simply returns the value from either column K or L based on the matching conditions and you may easily extend it or add more conditions.
Essentially, I have two columns of data and I would like to know if a given value in Column A matches any value in Column B within a certain delta value.
I don't think an approximated VLOOKUP would do the trick here. The values are dates and times of day (as in 8/12/14 1:43:02 PM) and I want the delta value to be <15 seconds.
So if A1 is 8/12/14 1:43:02 PM and B156 is 8/12/14 1:43:08 PM, return a boolean.
Since comments tend to get long, here is a long comment, or a short answer.
To compare timestamps, you can write =ABS(A1-B1)<1/5760. Numeric conversion is automatic, and 1/5760=15/86400, or 15 seconds, considering that for Excel, a day equals 1.
Here is an example, for one value in column A.
My Excel is french, VRAI means TRUE. The date/time format is maybe not the same as yours, but it's only visual.
In english, the formula are:
C1: =MATCH(A1,$B$1:$B$21)
D1: =INDEX($B$1:$B$21,C1)
E1: =INDEX($B$1:$B$21,C1+1)
F1: =OR(ABS(D1-A1)<1/5760,ABS(E1-A1)<1/5760)
Of course, you don't really need 4 columns to do this, but it's easier to understand.
See also the help for MATCH function: MATCH finds the largest value that is less than or equal to lookup_value. The values in the lookup_array argument must be placed in ascending order.
So you get the index of the value just before, and you have to test this value (first part of the OR, and D1) and the next value (second part, and E1).
Try this array formula:
=IFERROR(MATCH(TRUE,ABS(A2-TIME_RANGE)<EQ_15_SEC,0),"not found")
This will return either the index of the item in column B that satisfies the 15 second rule, or "not found".
TIME_RANGE is one range of values you want to check, like column B
A2 is the candidate in column A on this row. You can fill the formula down.
EQ_15_SEC just points to a cell where I did the calculation =15/60/60/24
This is an array formula, so commit by pressing Ctrl+Shift+Enter (not just Enter)
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
