I am having trouble using INDEX and MATCH functions in excel. Say I have the following data:
A B C D
Year Month Site Count
2004 3 X1 54
2006 6 X3 10
2005 10 X5 15
And I want to arrange it like this
E F G H I J K
Year Month X1 X2 X3 X4 X5
2004 1
2004 2
2004 3 54
2004 4
2004 5
2004 6
...
2005 10 10
...
2006 6 15
I have the following formula (I want to match the Site, Year and Month):
=IFERROR(INDEX($D$2:$D$4,MATCH(G$1,$C$2:$C$4,0),MATCH($E2,$A$2:$A$4,0),MATCH($F2,$B$2:$B$4,0)),"")
and it seems to work fine for the first column (G) but when I autofill the rest of the columns (H:K) it doesn't work. Any ideas? Thanks.
I'd take a different approach than using all these nested matches, and create a searchable column with unique values and MATCH that column to get a row to feed into the INDEX.
Insert 2 rows between Cols D and E, putting the 2nd appearance of 'Year' in Column G. (Because I like some whitespace)
Paste this formula in E2 and copy it to E3:E4
=CONCATENATE(C2,"-",A2,"-",B2)
If it bothers you, hide Column E.
Then paste this formula in I2 and copy it to I2:M4:
=IFERROR(INDEX($D$2:$D$4,MATCH(CONCATENATE(I$1,"-",$G2,"-",$H2),$E$2:$E$4,0),0),"")

My data looks like this: [with 10k rows and 26 something columns]
FID Year I1 I2 I3 I4 I5
1 2009 a b c
1 2010 a d e g
1 2011 g f h
1 2011 h f j i k
1 2013 h t g k m
1 2014 a b c d
1 2014 e d f c l
1 2014 h i j k d
1 2014 a b d
I want the count of unique 'I's for every year. Output like this:
FID Year Count(Unique)
1 2009 3
1 2010 4
1 2011 6
1 2013 5
1 2014 11
What I have tried till now:
I tried this =COUNTIF("$C2:$G2,"*") and then summing for the same year. Until I realized that 'I's are being repeated.
Then I tried concatenating all I's for the same year. Failed.
Then I tried converting the data into the long format with [FID+Year] as the key. So that I can remove duplicates. But failed due to 'not enough memory' to perform the task.
Any help would be appreciated as to how to solve this problem. Thanks.
This is the formula that you need:
=SUM(IF(COUNTIF(A1:E1;A1:E1)=1;1;0))
It is an array formula, thus you need Ctrl+Shift+Enter to execute it.
If your values were numbers, it would have been easier. Like this:
=SUM(IF(FREQUENCY(A1:E1,A1:E1)>0,1))
It is not an array formula.
I came up with this for you and here is the screenshot of the results:
Here is the formula you can try from cell K2 and drag it down:
=IFERROR(SUMPRODUCT((OFFSET($C$1,MATCH(J2,$B$2:$B$10,0),0,COUNTIF($B$2:$B$10,B2),5)<>"")/COUNTIF(OFFSET($C$1,MATCH(J2,$B$2:$B$10,0),0,COUNTIF($B$2:$B$10,B2),5),OFFSET($C$1,MATCH(J2,$B$2:$B$10,0),0,COUNTIF($B$2:$B$10,B2),5)&"")),0)
Explanation:
What this does is to use these two basic formulas.
=SUMPRODUCT((range<>"")/COUNTIF(range,range&"")), this is to find unique values in a range and also ignore the blanks
=OFFSET(reference,rows,cols,height,width), this is to find the range that you want to evaluate
Hope this can solve your problem.
I have two problems here.
The data is as follows:
Col X Col Y
A 10
A 12
A
A 32
B 11
B 31
B 9
C 8
C 7
C 3
D 1
D 3
D
D 9
I need to do the following:
Count the entries in Column Y using the Categories in Column X, for ex. A repeats 4 times in Column X but has 3 total corresponding numbers in column Y, i need the 3 count of the numbers in Column Y.
Calculate the median of those numbers using the category (excluding blanks whenever there are, not to be assumed as 0 by the code), for ex. Median for A is 12, Median for D will be 3.
Please help.
So 1 is:
=COUNTIFS(X:X,"A",Y:Y,"<>")
2 is:
=MEDIAN(IF(X:X="A",IF(NOT(ISBLANK(Y:Y)),Y:Y)))
Hold down ctrl + shift when you're using 2 as it's an array formula
I have the following data.
Z Y Z Z
A1 A2 A3 A4 Total
1 2 5 10 16
2 3 5 11 18
3 4 6 12 21
4 4 7 12 23
I want to sum the rows using Just Zs ( the name of columns). I have a big data set, so I want to write a function to find out Zs in the whole sheet and the then sum them (Total).
Any Help would be appreciated
This can be done with SUMIF():
=SUMIF($1:$1,"Z",2:2)
NOTE
With the above formula it is using full row references so DO NOT put "Z" on top of the total column or it will throw circular errors.
If you want to have "Z" above it then you need to define the ranges:
=SUMIF(A$1:D$1,"Z",A2:D2)
How does this work:
=Sum(If(A$1:D$1="Z",$A$2:$D$100))
Assuming your headers are in row 1, columns A to D, and your data starts in row 2, and goes to row 100.
I have a data set of roughly 405,000 rows and 23 columns. I need the records where the value in column "D" is the same as the value in column "H" for that row.
So for
A B C D E F G H
13 8 21 ok 3 S - of
51 7 22 no 3 A k no
24 3 23 by 3 S * we
24 4 24 we 3 S ! ok
24 9 25 by 3 S # we
75 2 26 ok 3 S 9 ok
etc...
I'd get back the 2nd row, the 6th row, etc...
A B C D E F G H
51 7 22 no 3 A k no
75 2 26 ok 3 S 9 ok
Based on other posts like: Formula to find matching row value based on cells in multiple columns I tried using a Pivot Table, but it complains I can't put either of my two columns in the "Columns" area because there is too much data. With both columns in the "Rows" area, I get a relationship of D to H, but I can't then find a way to filter on only those where D = H.
I've also looked into countifs(), vlookup, and index / match functions, but I can't figure this out. Help please.
I would do a simple "IF()" formula in a new column.
For your example add a new column I and use the following formula in the first data row (I2):
=IF(D2=H2,"Yes","No")
Fill down to the end of the data.
Then using Excel filters or countif you can check the number of "Yes" vs "No" in your data.
Please consider the following Excel worksheet:
A B C D E F
---------------------------
1 10 5 999 999 10 25
2 5 1 10 999 5 21
3 5 1 100 1 5 112
What I need is a formula in each cell of column Fto add up the values of each row, whilst ignoring 999 values. So usually the formula in cell F1 would be:
=SUM(A1:F1)
But this obviously returns 2048, not 25. So my question: what formula will add up all values, ignoring 999 (missing) values?
Extending from comment (and thanks to #SiddharthRout):
You can use
=SUMIF(A1:E1,"<>999")
in column F.
