Compare two Excel columns, output cells in A that do not appear in B - excel

I am trying to compare two columns in excel, A and B. Column A contains a complete list of customer numbers. Column B contains an incomplete list of the same customer numbers. So if a customer number is in A, but not in B then output that number to column C.

I'd use the MATCH function in combination with ISNA.
If I have the following table
A B C
1 4
2 3
3 1
4 7
5 2 5
6 6
7
I put in column 'A' the full customer list, and in column B is a random ordered partial list. I then put the function in C1 (and the rest of column C):
=IF(ISNA(MATCH(A1,B:B,0)),A1, "")
Now I see the values '5' and '6' only in column C, because those are the only two numbers that don't appear in column B.

In Cel C1 =IF(ISERROR(VLOOKUP(A1,$B$1:$B$10,1,FALSE)),A1,"")
Adjust for row counts and fill down against column A.

I think you're looking for something like this:
=IF(ISERROR(MATCH(A1,B1,0)),A1,"")
Propegate that formula along your new column and it'll reprint the populated Column A when Column B is a no match.

(I believe I read the original question wrong, and am going on the assumption that column A and B are already sorted where the values will line up.)

Move the value of all cells in a column to their corresponding excel row number

Let's say i have the below list of Whole numbers in Column A. If you observe the list of numbers, you will see that number "5" and 6 is missing.
A
3
2
4
1
7
8
what I want to achieve is to place (sort) the numbers on the column such that each cell value will take its position according to excel row numbering. which means:
I should have something like this
1
2
3
4
7
If it's as simple as stated, this should work.
In column B, say:
=IF(COUNTIF(A:A,ROW())>0,ROW(),"")
Note: It does not account for duplicates, or anything complicated really.
Further Note: To clarify, all this does is check if the row that the formula is in, is in column A. If it is, then it returns the current row.

To give you a context of the number of rows. Sheet 1 will be bigger with more than 1000 rows. Sheet 2 (Mapping Table) is constant set of rows. Currently it is about 100 rows.
You can use a formula like shown below using LOOKUP(), SEARCH() with SUBSTITUTE()
• Formula used in cell B1
=IFERROR(SUBSTITUTE(A1,LOOKUP(9^9,SEARCH($D$1:$D$3,A1),$D$1:$D$3),
LOOKUP(9^9,SEARCH($D$1:$D$3,A1),$E$1:$E$3)),A1)
There you go. There may have other better solution. This is what I got.
All in column B.
=IFERROR(CONCAT(MID(A1,1,MATCH(1,(CODE(MID(A1,ROW($Z$1:$Z$255),1))<90)*(CODE(MID(A1,ROW($Z$1:$Z$255),1))>=65),FALSE)-1),INDIRECT(CONCAT("sheet2!b", MATCH(MID(A1, MATCH(1,(CODE(MID(A1,ROW($Z$1:$Z$255),1))<90)*(CODE(MID(A1,ROW($Z$1:$Z$255),1))>=65),FALSE), LEN(A1)), Sheet2!$A$1:Sheet2!$A$300, 0)))),A1)
Break down is as follow;
Let's start put things from Column C onward.
Column C, to find the index of the first capital letter from the text.
ref: http://dailydoseofexcel.com/archives/2007/02/21/find-position-of-first-capital-letter-in-a-string/
=MATCH(1,(CODE(MID(A1,ROW($Z$1:$Z$255),1))<90)*(CODE(MID(A1,ROW($Z$1:$Z$255),1))>=65),FALSE)
Column D, cut the name part by using upper case letter index from column C, sp_abc_Jabba_the -> Jabba_the
=MID(A1, C1, LEN(A1))
Column E, search row number from Sheet2 by matching Column D's name with Sheet 2's Column A, this will get matching row number from Sheet2.
=MATCH(D1, Sheet2!$A$1:Sheet2!$A$300, 0)
Column F, get Sheet2's Column B value by the row number from Column E.
=INDIRECT(CONCAT("sheet2!b", E1))
Column G,
Cut "sp_abc_" from "sp_abc_Rick"
Concat "sp_abc_" with Column F's "Morty".
If there is any error, use Column A value as default.
. <- this dot is intentional. please ignore.
=IFERROR(CONCAT(MID(A1,1,C1-1),F1),A1)
Try:
Formula in B1:
=BYROW(A1:A10,LAMBDA(a,LET(b,TEXTBEFORE(a&"|","_"&A12:A14&"|",-1),IFERROR(CONCAT(IF(b&"_"&A12:A14=a,b&"_"&B12:B14,"")),a))))
The concatenation with a "|" would assert we only replace values when at the exact end of the input. Just in case there would be a stray (for example) 'Rick' somewhere before the end.

How to recursively calculate mean of values based on values present in another cell of the same row in Excel

I have a spreadsheet with two columns of values, containing 1000 values each. The first column (column A) contains these values:
W
W
W
T
T
T
The second column (column B) contains these values:
1
2
3
4
5
6
Here is an image of the spreadsheet:
Can you please tell me if there is a way to recursively calculate the mean of those values in column B that have the same value in column A? In my case, the output should be a new column that looks like this:
2
5
As you can see, "2" is the mean of values in column B that has "W" in column A, while "5" is the mean of values in column B that has "T" in column A.
This type of question can be handled using the SubTotals feature, using Average() as the function to be used (instead of the default Sum() function).

Sum rows containing only the first appearance of value in separate column

I have a table that looks something like this:
Column A | Column B
A 1
B 2
C 3
A 4
What I want to do is get the sum of the values in Column B, but only first the first occurrence of each value in Column A. Thus, the result I want to get is (1 + 2 + 3) = 6 (Adding the first three rows, but omitting the fourth, because a row with 'A' in Column A has already included in the sum).
I've tried looking at Frequency, but I haven't been able to figure out how to use it properly to get the result I want.
Use SUMPRODUCT and MATCH:
=SUMPRODUCT(--(ROW(A1:A4)=MATCH(A1:A4,A:A,0)),B1:B4)

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.
