Find Same Duplicate Max Value Excel - excel

So i try return value from table which has same percentage using Index match, but it return the same value twice instead of another value that has the same percentage
Here is my Excel View, is there any help for my problem?
Here is my excel formula
enter image description here

1st: you can't and shouldn't use Match(...,...,-1) in unsorted data, use Match(...,...,0) only
2nd: you can't search for the 2nd similar because... the program has no way of knowing there are 2|3... similar objects. So you must get the positions of ranks when sorting them, and then use that position to get the score and value you want with index(). So Sorting and getting the Position (or ROW()) must be done same time.
3rd: the way to do this is with Matrix formulas that work for on a pre-specified number of cells: So you can look in a table of 200 elements for 10 results and have provision to avoid errors if results are <10, but you'll never get 11. Also Hide the column with the positions to gain clarity...
try this formula:
= LARGE( ROUND( OFFSET($B$3,,,$G$1)*1000,0)*100 + ROW(OFFSET($A$1,,,$G$1)),ROW(OFFSET($A$1,,,$G$2)) )
to get a sorted list from column B Starting w B3 with N rows (N specified in G1) and look for m results (m specified in g2). Offcourse adjust the bolds as needed for your project
4th: Enter the formula in a Column that you will hide, with ctrl+shft+Enter (to enter as matrix) and expand it in as many cells as the results you expect (in the example 2) by selecting them starting with the cell with Array-formula, then F2 (to edit formula) and ctrl+sht+enter. Mind that Arrays can only be EXPANDED, if you want to shrink it you have to delete it and rebuild it...
5th: get the Index with =MOD( ... ,100) ,where ... are the results from steps 3&4
1ST AGAIN: Another simple solution (*not to my Liking). Within your Match(item,range,-1) you should compare item with previous item and use Offset. In your formula you can write:
=Index($C$12:$C$23, Match(DF19, Offset( $CQ$12:$CQ$23 ,if(DF19=DF18, Match(DF19,$CQ$12:$CQ$23,0),0) ,-1) ))
thus pushing the search matrix further down to avoid finding the same.
(added code with BOLD, rest should be same to your original code)

Function to search for specific number and then to further search for the prefix

I have a huge amount of data to process in which 4 points with a related prefix needs to be subtracted from each other.
Data consists of ID and x value
Example
ID = 290.12, 290.03, 290.06, 290.09, 300.12, 300.03, 300.06, 300.09, 301.12, 301.03, 301.06, 301.09
(let's call prefix a "ring number" and suffix time on the clock)
X value = any numerical value for each ID assigned
What I'm hoping to do is to search for the first number before the dot i.e. 300 and then subtract the value of 300.06-300.12 in one cell and in another cell 300.03-300.09.
(The subtraction is just an example, how I need to manipulate with the numbers is slightly more complicated, but I got this one under control)
This is my actual Data and what I need to produce is to the right of the raw data. At the moment, I'm doing it manually for each set of "rings"
Anyone knows how to approach this? I'm thinking vlookup, but I'm not very proficient in excel.
New Excel
I tried vlookup, but I don't know how to construct the formula and I run out of ideas.
Edit:
I found out that REDUCE is no requirement in this case, so it can be shortened to:
=SQRT(SUM(((INDEX(B:D,XMATCH(I3+0.09,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(I3+0.03,A:A),SEQUENCE(1,3)))^2)))
You could change +0.09 and +0.03 to your needs and may reference them using LET() for easy maintaining:
=LET(id,I3,
_id1,0.09,
_id2,0.03,
SQRT(SUM(((INDEX(B:D,XMATCH(id+_id1,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id2,A:A),SEQUENCE(1,3)))^2))))
Previous answer:
=LET(
id,I3,
_id1,0.09,
_id2,0.03,
SQRT(
REDUCE(0, SEQUENCE(1,3),
LAMBDA(x, y,
x+((INDEX(B:D,XMATCH(id+_id1,A:A),y)
-INDEX(B:D,XMATCH(id+_id2,A:A),y))
^2)))))
This formula looks for the matching value of the id value I3 + _id1 minus the matching value of id value + _id2 for columns B to D and adds the ^2 results per column. Then it calculates it's square root.
You can change _id1 and _id2 to your needs.
To calculate the Delta (as shown) at once you could use:
=LET(id,I3,
_id1,0.09,
_id2,0.03,
_id3,0.12,
_id4,0.06,
x,SQRT(SUM((INDEX(B:D,XMATCH(id+_id1,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id2,A:A),SEQUENCE(1,3)))^2)),
y,SQRT(SUM((INDEX(B:D,XMATCH(id+_id3,A:A),SEQUENCE(1,3))-INDEX(B:D,XMATCH(id+_id4,A:A),SEQUENCE(1,3)))^2)),
(x-y)*1000)
You can have a column of unique values of the integers and a new column where you reference these values as id and drag down the formula to get your row by row result
In another column you can refer to these columns and sort per the second column using SORTBY()

Excel Index to look up multiple values

I have a small data set of 2 columns and several rows (columns A and B)
I want to return each instance of codeblk 3 in a formula that is elsewhere in my sheet, (so a vlookup is out as it only shows the first instance) if it does not appear then a message to say its not there should come up.
I have the formula partially working but i cant see the reason why its not displaying the values.
My formula is as below:
This is an array
{=IF(ISERROR(INDEX($A$55:$B$70,SMALL(IF($B$55:$B$70=3,ROW($B$55:$B$70)),ROW(1:1))-1,1)),"No value's produced",INDEX($A$2:$C$7,SMALL(IF($B$55:$B$70=3,ROW($B$55:$B$70)),ROW(1:1))-1,1))}
The result that shows up is only "No values produced" but it should reflect statement B, C and D in 3 separate cells (when changing ROW(1:1), ROW(2:2) etc)
{=SMALL(IF($B$56:$B$69=4,ROW($B$56:$B$69)),ROW(1:1))} - This produces the result 68 which is the correct row.
Any ideas?
Thanks,
This is an array formula - Validate the formula with Ctrl+Shift+Enter while still in the formula bar
=IFERROR(INDEX($A$55:$B$70,SMALL(IF($B$55:$B$70=3,ROW($B$55:$B$70)-54),ROW(1:1)),1),"No value's produced")
The issue you are facing is that your index starts it's first row on $B$55, you need to offset the row numbers in the array to reflect this. For example, the INDEX contains 16 rows but if you had a match on the first row you are asking for the 55th row from that INDEX(), it just can't fulfil that.
EDIT
The offset was out of sync as your original formula included another -1 outside of the IF(), I also left an additional bracket in play (the formula above has now been edited)
The ROW() function will essentially translate $B$55:$B$70 into ROW(55:70) which will produce the array {55;56;57;58;59;60;61;62;63;64;65;66;67;68;69;70} so the offset is needed to translate those row numbers in to the position they represent in the indexed data of INDEX().
The other IF() statement then produces and array of {FALSE;2;3;4;FALSE etc.
You can see these results by highlighting parts of the formula in the formula bar and hitting F9 to calculate.

MAX + Left Function Excel

I am trying to get the max value of a column based on the Left function
What I am doing is the following :
These are the results I get when i write this into column C :
=MAX(LEFT(A:A, 2))
But what I truly want is to get in column C the max value of all column A not for each cell.
So the result should be in this case 90 for all rows.
What should be the formula here?
Just another option that gets entered normally:
=AGGREGATE(14,6,--LEFT($A$1:INDEX(A:A,MATCH("ZZZ",A:A)),2),1)
Array formulas will calculate the enitre referenced array. So care should be taken to limit the number of iterations to only the data set.
The $A$1:INDEX(A:A,MATCH("ZZZ",A:A)) part of the formula does that. It finds the last cell in column A with data in it and sets that as the upper bound. So in this instance the reference range is A1:A3. But, it will grow dynamically as data in Column A is added, so no need to change the formula each time data is added.
Update 2
Here is another solution which I think is better than my original (below)
=INT(SUMPRODUCT(MAX(SUBSTITUTE(A:A,"-",".")*1)))
it can be entered as normal (just Enter)
Orignal Answer
You need numbers and arrays
=MAX(IFERROR(LEFT(A:A,2)*1,0))
Let's break this down. Multiplying by turns your strings into numbers - since Left only returns a string
LEFT(A:A,2)*1
Unfortunately this method returns #Value if you multiply an empty string by 1. You will definitely have some empty strings in the range A:A so we wrap the whole thing with an IFERROR function.
IFERROR(LEFT(A:A,2)*1,0)
Now we still need excel to treat this as an array (i.e. a whole column of numbers, rather than just one number). So we put the MAX formula in and enter it with Ctrl+Shift+Enter rather than just Enter. The result is that the formula looks like this in the formula bar
{=MAX(IFERROR(LEFT(A:A,2)*1,0))}
which would return 90 in your example, as required
Update 1
If you are using Excel 2013 or later, you can also use the NUMBERVALUE function
=MAX(NUMBERVALUE(LEFT(A:A,2)))
again, enter it with Ctrl+Shift+Enter

Excel: Obtain the row of the smaller value

I have the following columns:
A - Original values, B - Absolute values, C - sorted absolute values
(I obtain the ordered values (C) using the SMALL formula for the given range - see the link bellow)
I need to know for each ordered absolute value, if the original value was or not negative:
So in the picture the red columns I filled-in manually...
Is there a way to automatize that via a formula ?
Here is the link to the sandbox in Excel Online: http://1drv.ms/1Vu2MZ4
If the first link does not work, the same thing and formulas on Google Sheets
A partial answer, which might be enough if column E in your screenshot is what you want and column D was a helper column intended to make column E easy to compute.
The problem with ABS() is that it loses information. Instead of using that, use a function which doesn't lose information but also doesn't change the sort order and which makes it possible to recover the absolute value after sorting. One way is to leave positive numbers alone but send negative numbers to their absolute value + 0.5. For example,
In B2 enter
=IF(A2 >= 0,A2, 0.5+ABS(A2))
In C2 enter
=SMALL($B$2:$B$6,-1+ROW())
In D2 enter
=INT(C2)
To recover the absolute values. Finally, in E2 enter
=IF(C2=D2,FALSE,TRUE)
(copying all of the formulas down).
In your case and for your locale =MATCH(C2; $B$2:$B$6; 0) and = INDEX($A$2:$A$6; MATCH(C2; $B$2:$B$6; 0)) < 0 will do but beware of cases where you have the same value both negative and positive.

Sort Order formula to alphabetise in Excel

I am currently drawing up a spreadsheet that will automatically remove duplicates and alphabetize a list:
I am using the COUNTIF() function in column G to create a sort order and then VLOOKUP() to find the sort in column J.
The problem I am having is that I can't seem to get my SortOrder column to function properly. At the moment it creates an index for two number 1's meaning the cell highlighted in yellow is missed out and the last entry in the sorted list is null:
If anyone can find and rectify this mistake for me I'll be very grateful as it has been driving me insane all day! Many thanks.
I'll provide my usual method for doing an automatic pulling-in of raw data into a sorted, duplicate-removed list:
Assume raw data is in column A. In column B, use this formula to increase the counter each time the row shows a non-duplicate item in column A. Hardcord B2 to be "1", and use this formula in B3 and drag down.
=if(iserror(match(A3,$A$2:A2,0)),B2+1,B2)
This takes advantage of the fact that when we refer to this row counter in our revised list, we will use the match function, which only checks for the first matching number. Then say you want your new list of data on column D (usually I do this for display purposes, so either 'group-out' [hide] columns that form the formulas, or do this on another tab). You can avoid this step, but if you are already using helper columns I usually do each step in a different column - easier to document. In column C, starting in C3 [C2 hardcoded to 1] and drag down, just have a simple counter, which error-checks to the stop at the end of your list:
=if(C2<max(B:B),C2+1," ")
Then in column D, starting at D2 and dragged down:
=iferror(index(A:A,match(C2,B:B,0)),"")
The index function is like half of the vlookup function - it pulls the result out of a given array, when you provide it with a row number. The match function is like the other half of the vlookup function - it provides you with the row number where an item appears in a given array.
Hope this helps you in the future as well.
The actual reason that this is going wrong as implied by Jeeped's comment is that you can't meaningfully compare a string to a number unless you do a conversion because they are stored differently. So COUNTIF counts numbers and text separately.
20212 will give a count of 1 because it is the only (or lowest) number.
CS10Z002 will give a count of 1 because it is the first text string in alphabetical order.
Another approach is to add the count of numbers to the count if the current cell contains text:-
=COUNTIF(INDIRECT("$D$2:$D$"&$F$3),"<="&D2)+ISTEXT(D2)*COUNT(INDIRECT("$D$2:$D$"&$F$3))
It's easier to show the result of three different conversions with some test data:-
(0) No conversion - just use COUNTIF
=COUNTIF(D$2:D$7,"<="&D2)
"999"<"abc"<"def", 999<1000
(1) Count everything as text
=SUMPRODUCT(--(D$2:D$7&""<=D2&""))
"1000"<"999"
(2) Count numbers before text
=COUNTIF(D$2:D$7,"<="&D2)+ISTEXT(D2)*COUNT(D$2:D$7)
999<1000<"999"
(3) Count everything as text but convert numbers with leading zeroes
=SUMPRODUCT(--(TEXT(D$2:D$7,"000000")<=TEXT(D2,"000000")))
"000999" = "000999", "000999"<"001000"
