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"

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()
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.
I'm pulling my hair right now trying to achieve that without VBA.
I do not want any VBA and I know It's easy to do with barely more than two lines of vba code.
Here is a simplified template of the type of table I'm working with.
The objective is : With one formula Return the column where the three specified values are matched. The value Im searching for will be somewhere on the sheet where the formula will be.
Just put them as value in the formula if you have one that can achieve that.
Best regards and thanks in advance if anyone help me restore my mental sanity.
Assuming a data setup like this:
This formula is in cell F1:
=SUMPRODUCT((B1:C1&B2:C2&B3:C3=F2&F3&F4)*(COLUMN(B1:C1)))
Adjust ranges to suit your actual data
Explanation:
It combines values of the columns' rows into a single string (so in this example, it would be {"KPI ADATEDATA TYPE","KPI BDATEDATA TYPE"})
It then compares those results to a combined string of what you're looking for: "KPI ADATEDATA TYPE" converts results to TRUE/FALSE so you end up with {TRUE,FALSE} (because the first combined string with KPI A matches)
Then it gets all possible column numbers of the results: {2,3} in this case for columns B and C
The multiplication then converts the TRUE/FALSE's into 1s and 0s respectively so you end up with {1,0}*{2,3}
Because there can assumably only be a single match, this results in the correct column number being the only value to be multiplied by 1, so results are {2,0}
The SUMPRODUCT then sums the results, and since there is only a single non-zero number, it must be the column index.
I am not into Excel and I have this problem trying to sum the values of 2 different column and put this result value into a cell.
So basically I have the D column containing 2 values (at the moment only 2 but will grows without a specific limit, I have to sum all the values in this column). These value are decimal values (in my example are: 0,3136322400 and 0,1000000000).
Then I have an I column containing the same type of value (at the moment only one but also the values in this column can grow without a specific limit...in my example at this time I have this value −0,335305)
Then I have the K3 cell where I have to put the sum of all the valus into the D column and all the values into the I column (following my example it will contain the result of this sum: 0,3136322400 + 0,1000000000 −0,335305.
Following a tutorial I tried to set this simple forumla in the K3 cell:
=SUM(A:I)
The problem is that in this cell now I am not obtaining the expected result (that is 0.07832724) but I am obtaining this value: 129236,1636322400.
It is very strange...I think that maybe it can depend by the fact that the D and the I column doesn't contain only number but both have a textual "heder" (that is the string "QUANTITY" for both the cells). So I think that maybe it is adding also the number conversion of this string (but I am absolutly not sure about this assertion).
So how can I handle this type of situation?
Can I do one of these 2 things:
1) Adding the column values starting from a specific starting cell in the column (for example: sum all the values under a cell without specify a down limit).
2) Exclude in some way the "header" cells from my sum so the textual values are not considered in my sum.
What could be a smart solution for my problem? How can I fix this issue?
The sum function can take several arguments.
=sum(d2:d10000, i2:I10,000, more columns )
This should remove the header from the calculation.
If you turn your data into an Excel Table (Insert > Table), you can use structured referencing to address a table column, excluding the header.
=SUM(Table1[This Header],Table1[That Header])
Then you don't need to reference whole columns. If you add new data to the table, the formula will take that into account.
So I've looked up tutorials on how to do this, and I'm still struggling, so I could use some expert help. I know it involves a very complex nested formula with things like SMALL, ROW, INDEX, etc...
So here are two screenshots that provide a sample of what I'm looking for. In realities there is over 1000 rows, but this makes it easier for you guys.
So here is my first example, lets call this Sheet1!:
Code, ID_1 and ID_2. So as you can see (and just focus on the input in A2) there will be two separate IDs in the linked workbook. That sheet, or at least a tiny sample of it, looks like this:
In the first column we see the code we're looking for (which is what we have in A2 of the first one), each of them with different IDs. So as I'm sure you can tell by now, I'm looking for a formula that will allow me to return those values in ID_1 and ID_2 in the first sheet.
I have been going at this for an hour and I'm stumped, so I would greatly appreciate any help provided!
This is a more generic code if the ids are NOT listed consecutively: Obviously I have done this as an example to take in a more general case where the ids occur anywhere throughout the second dataset, AND where there are potentially several.
IFERROR(INDEX($V$2:$V$15, SMALL(IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE), COLUMNS($N2:N2))-ROW($V$1), 1), "")
This formula must be entered with Ctrl-Shift-Enter before copying across and down! Note all absolute and relative referencing/locking ($ signs)
The logical steps in constructing such a formula:
1) We use IF function to test if the values in the column U match the value in column M.
2) In the 'value-if-true' parameter, we will get the corresponding row number of values in column U. These numbers will be fed later in the SMALL function.
3) In the value-if-false part, we just return false, as that will later be used as a non-number in the SMALL function
Above 3 steps in the part: IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE)
4 ) We have now an array of mixed row numbers and FALSE values, which we want to feed to the INDEX function to simply get the corresponding value in column V(our second datset). BUT as we wish to retrieve the different row matches for each code, we have to fish them out of the mixed array with the SMALL function.
5) using our columns as an incrementer, we apply the SMALL function to the array with a varying k parameter. We USE the COLUMNS function (note carefully the different $ sign usage), so that as we drag the formula across, the column count increments: COLUMNS($N2:N2) - giving K values of 1, 2, 3, 4 as we drag the formula across from column N to column Q. Note that it is useful that the SMALL function disregards FALSE values when looking through the array for the values by size.
6) There is an adjustment to account for the fact that the rows are relative to the 'Ids' range which we will feed into the INDEX function to retrieve the different ids. SMALL(IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE), COLUMNS($N2:N2))-ROW($V$1).
This can be avoided if we use the entire column V as the look-up array parameter in the INDEX function, but that's another way...
7) This resulting value can now be passed to the INDEX function to obtain the various ids. The column_num parameter of 1 which I put in the function isn't necessary in a single-column look-up array, but is there for completeness.
8) The entire construction is then wrapped in an IFERROR function to give an empty string if there is no match, but some people may wish to have error outputs there...
well if the two ID will be consecutive in the second list try this:
=index('workbookname'SheetName!columnrangeofserialnumbers,match(A2,'workbookname'Sheetname!columnrangeofIDs,0))
Assuming your other workbook is called Serials, and all the info is on sheet1 you would enter the follow in B2:
=index('serials'sheet1!$B$2:$B$1000,match(A2,'serials'sheet1!$B$2:$B$1000,0))
in C2 enter the following (assuming ids will show up consecutively)
=index('serials'sheet1!$B$2:$B$1000,match(A2,'serials'sheet1!$B$2:$B$1000,0)+1)
This only works if the other workbook is open as far as I know and with the understanding that the two ID will be listed consecutively in the list.
