Excel mapping and create a new column - excel

Excel file columns:
A B C
2 two 3
5 five 8
3 three 10
8 eight 11
12 one 15
I want to create a new column Din same file like below:
A B C D
2 two 3 three
5 five 8 eight
3 three 10
8 eight 11
12 one 15
I want to map C and A and if there's a match D takes values of B.
Example: Value 3 in C is present in A, so D will take corresponding B value three.
Thanks!

So building on BigBen's additional suggestion of using an IFERROR, I believe you want something akin to this in Column D:
=IFERROR(VLOOKUP(C1, A:B, 2, FALSE), "")
... and then drag down the formula throughout Column D
Now, there are some assumptions being made here:
Your data does not have any header row, ala the data starts in Row 1, not Row 2
You want empty/blank values where there is no exact match (this is BigBen's IFERROR suggestion). Your current question layout seems to suggest this. Otherwise, you'll get #N/A in all those blank cells in Column D.
EDIT: To confirm, I used your data (though I started in Row 2), and here's how it looked after -

If one has DA-functionality you could use:
1) - Excluding empty cells using FILTER:
Formula in D1:
=FILTER(B1:B5,COUNTIF(C1:C5,A1:A5)>0)
2) - Including empty cells using XLOOKUP:
Formula in D1:
=XLOOKUP(C1:C5,A1:A5,B1:B5,"")
If one does not have access to DA-functionality you could use:
1) - Excluding empty cells using INDEX, MATCH and SMALL:
=IFERROR(INDEX(B$1:B$5,SMALL(IFNA(MATCH(C$1:C$5,A$1:A$5,0),""),ROW(A1))),"")
Note 1 - This needs to be array entered through CtrlShiftEnter
Note 2 - Alternatively, one could use a non-array entered approach including AGGREGATE as per #basic: =IFERROR(INDEX(B$1:B$5,AGGREGATE(15,6,MATCH(C$1:C$5,A$1:A$5,0),ROW(A1))),"")
2) - Including empty cells using VLOOKUP:
Please refer to the other answer given by #Gravity here.
Basically the difference between both approaches could be vizualised like:

extract ranges from column values

I've column of values 1-10 missing 4 and 7 can I extract 1-3,5-6,7-10.
Currently I'm using this formula =IF(A3=A2+1,C2,C2+1) which gives me helper column sort of help
but my list is long If I could extract ranges that would be helpful.
There are no duplicates
I'm not sure if I understand exactly what you mean, but this is what I have done until now: I have copied the same columns A and B, and I have added following columns:
Column C : =COUNTIF(B$2:B$16,B2)
Column D : =IF(AND(C2=C3,C3<>C4),"End",IF(AND(C2<>C3,C3=C4),"Begin"))
The result looks as follows:
As you can see:
The number 1 from column B ends at row 6, and D6 indeed indicates "End".
The number 2 from B starts at row 7 (D7="Begin") and ends at row 8 (D8="End").
The numbers 3 and 4 are not correctly handled but:
As far as 5 is concerned: it starts at row 11 (D11="Begin") and ends at row 15 (D15="End").
There still is some finetuning to do but I guess you see how the ranges start being unfold.

Get Spill-result to reference correct row #

As a result of this closed topic I started wondering myself the following:
Let's say we have data like this:
A
1
a
2
b
3
c
4
a
5
b
6
c
7
g
8
h

I want to divide the list into 3 (I used TEXTJOIN) and check which of the 3 of these is unique.
I used a combination of MATCH and COUNTIF (and SEQUENCE) for this.
Question:
I managed to get that correct, but wanted to get the 3 textjoin-results all at once as a spill range.
In the picture below you can see my results of attempts, but I couldn't get the TEXTJOIN to reference the correct column in it's spill-result. What is missing, or what am I doing wrong?
Not sure what you want for output.
If all you want is to determine which is/are unique entries, just use the UNIQUE function. Note the exactly_once argument.
For example:
C1: =OR(B1=UNIQUE($B$1:$B$3,,TRUE))
and fill down, but the formula will fill down automatically.
Edit:
I don't know how to get the TEXTJOIN function to spill down in groups of three like you want. However, to be able to enter the formula just once, and have the results appear in column B, and have that adjust as you add/remove entries from column A, you can use a Table structure.
In that case, row 1 would be the column headers, and the formula in B2 would be:
=IFERROR(TEXTJOIN(",",TRUE,INDEX([Column1],SEQUENCE(3)+(ROW()-ROW(Table2[#Headers]))*3-3)),"")`
No need to fill down.
Edit2:
To create a list of unique (listed only once) values from Column B in Column C, you can use the UNIQUE function. However, due to limitations on SPILL functions within a Table, this column cannot be part of the table.
In the example below, where Column C is NOT part of the table:
B2: =IFERROR(TEXTJOIN(",",TRUE,INDEX([Column1],SEQUENCE(3)+(ROW()-ROW(Table2[#Headers]))*3-3)),"")
C2: =UNIQUE(Table2[Column2],,TRUE)
Edit3:
If you were OK with omitting columnB, and reporting the unique triplets in separate cells instead of concatenated, you could do that with the UNIQUE function:
or, without a table,
=UNIQUE(INDEX($A:$A,SEQUENCE(COUNTA($A:$A)/3,3,2)),,TRUE)
Note that the start argument in the SEQUENCE function represents the first line of data in column A, (2 in this example)

Count with criteria for changing column in excel

I have a data looks like this:
a b c
1 3 4
2 3 3
4 1 2
2 4 2
In another worksheet, I want to do the following calculation:
whenever A1 returns a (header of data worksheet), count number of items that are smaller and equal to 2 in column "a". (result will be 2)
if A1 returns b, count number of items that are smaller and equal to 2 in column "b". (result will be 1).
A1 has already been preset with formula such that it will show a or b or c as conditions changed.
I need the formula to be lean... I actually have 6 headers, so if I keep on using if functions, I will probably have to set 6 if functions in one cell...that can be overwhelming. index match cannot provide a range to work on...Any suggestion? thanks
I don't know vba. If you could provide a workable vba code, i don't mind. but i don't know how to read it...>.< please provide user manual for that. lol, thank you~
If your data is found on Sheet1 and the a is found on column a, b is found on column b etc. enter this formula on then next sheet on b1 when a1 is the column value:
=COUNTIF(INDIRECT("Sheet1!"&a1&":"&a1),"<=2")
The Indirect is for adding text to your reference.
If your data sheet is Sheet1, you could try the array formula:-
=SUM((Sheet1!A1:C1=$A$1)*(Sheet1!A2:C5<=2))
Must be entered with CtrlShiftEnter
(actually there are 3 items less than or equal to 2 in column A)
Or you can use the SUMPRODUCT version if you prefer not to use an array formula:-
=SUMPRODUCT((Sheet1!A1:C1=$A$1)*(Sheet1!A2:C5<=2))
Or you can use this INDEX/MATCH method which is probably more efficient:-
=COUNTIF(INDEX(Sheet1!A2:C5,,MATCH(A1,Sheet1!A1:C1,0)),"<="&2)

Excel line up data

I'm a total Excel nub and can't find the answer I'm looking for. Must be easy peasy, but since I'm not into Excel I also don't know what to look for. Sorry if I'm having my question wrong.
I have output in Excel like this:
A 1
A 2
A 3
A 4
B 1
B 2
B 3
B 4
B 5
B 6
and I want it like this:
A 1 2 3 4
B 1 2 3 4 5 6
this question is quite complex in a way.
let me explain it more in detail:
as you see above, we have two columns A and B, you have text strings in column A , these text strings could be repeated. As you see in the example, there are 4 As, 5 Bs, 3 Cs 1 D and 3 Es. In column B each one of these strings have different corresponding values. For example, text strings B in column A has five corresponding values in column B, namely 11, 12, 13, 14, 15, and 16.
Now we want a list of UNIQUE values from column A, and lets say, we put this list in column C and then for each of these unique values in column C we want to list their corresponding cells in column B and put them HORIZONTALLY in front of each of these unique text strings in column C.
For this you need two kinds of formulas:
Formula 1 to calculate the list of the unique values in column A :
this goes in C2:(leave C1 empty)
=IFERROR(INDEX($A$1:$A$999;MATCH(0;FREQUENCY(IF(EXACT($A$1:$A$999;TRANSPOSE($C$1:C1));MATCH(ROW($A$1:$A$999);ROW($A$1:$A$999)); ""); MATCH(ROW($A$1:$A$999);ROW($A$1:$A$999))); 0)); "")
this is an array formula, so press ctrl+shift+enter to calculate the formula, and drag and fill down as many as you want in column C.
*Formula 2 to find and list horizontally the values from column B *
=IFERROR(INDEX($B$1:$B$999;SMALL(IF($C2=$A$1:$A$999;ROW($A$1:$A$999)-ROW($A$1)+1);COLUMN(A$1)));"")
this is an array formula, so press ctrl+shift+enter to calculate the formula, put this in D2 and drag and fill down until the last cell of column C. then select D2 to D6 and drag and fill horizontally. You should get all of the corresponding cells in front of each unique item.
P.S. adjust the formulas to meet your regional settings by replacing ; with , I suppose.
Finally here is the link to an example sheet downloadable from here .
This is very generic but hopefully will help.
Highlight the cells that you want to transpose to.
Type the equation..."=TRANSPOSE(B1:B4)" (edit as necessary).
While the cells are still highlighted, press "ctrl+shift+enter". (brackets should appear around the equation)
Finish editing the cells.

EXCEL match 2 columns against each other

I have two columns of data, they look something like this:
A B C D
1 2 SOME RECORD
2 6 SOME RECORD
3 10 SOME RECORD
4
5
6
7
8
9
10
So basically column A is a list of indices, where some of them appear in column C with corresponding records saved in column D. Column B is currently empty, and what I want to do is if say index 2 appears in both column A and column C (they matches), then put the record beside C2 in the cell B2. So essentially I want it to look like this:
A B C D
1 2 SOME RECORD
2 SOME RECORD 6 SOME RECORD
3 10 SOME RECORD
4
5
6 SOME RECORD
7
8
9
10 SOME RECORD
Can someone help please?!! Thanks!!!
UPDATE: I tried this and it doesn't work. The data in column D is calculated using a UDF and is refreshing every 1 second. The VLOOKUP function fails even though I can see the 2 indices are the same!! Is it because of the format of the cell or column? I.e. does vlookup compare data type as well?
Assuming your data in A starts from A1 - put in B1 the following and autofill:
=IFERROR(VLOOKUP($A1,$C:$D,2,0),"")
This includes handling of missing values.
You'll want this:
B1=VLOOKUP(A1, C:D, 2, FALSE)
This will look up the value in column A within the array spanning columns C and D. It will give you the value found in the second column (D). FALSE makes it an exact match, otherwise you might get 2 and 20 matching because hey, they're kind of similar...
