Finding elements that are unique in one column excel - excel

I have two columns in excel that have some shared data and some unique data to each column. What I want is to have two more columns that will have the data that is in Column A but not B and the data that is in Column B but not in A. I have tried using Vlookups but I don't think I can get what I am looking for by doing this.

For Col A items not in column B, try this array-entered formula (entered in some cell, then fill down until it returns blanks)
=IFERROR(INDEX(ColA,SMALL(IF(ISNA(MATCH(ColA,ColB,0)),ROW(ColA),""),ROWS($1:1))-1),"")
and for Col B items not in Column A:
=IFERROR(INDEX(ColB,SMALL(IF(ISNA(MATCH(ColB,ColA,0)),ROW(ColB),""),ROWS($1:1))-1),"")
The formulas assume that your data starts in row 2 (row 1 would be a label) and the ranges ColA and ColB also start in Row 2
The formulas also assume no blanks in the data. If there are empty cells, then use these formulas:
=IFERROR(INDEX(ColA,SMALL(IF(ISNA(MATCH(ColA,ColB,0))*(ColA<>""),ROW(ColA)),ROWS($1:1))-1),"")
=IFERROR(INDEX(ColB,SMALL(IF(ISNA(MATCH(ColB,ColA,0))*(ColB<>""),ROW(ColB)),ROWS($1:1))-1),"")

Easy with a PivotTable, if you are prepared to rearrange your data somewhat:

How to find non matching records from two columns while accounting for duplicate values in Excel

I have two large columns.
Column A contains 100,000 different numbers/rows. Column B contains 100,210 numbers/rows. They have the same numbers except column B has 210 extra rows. I need to be able get the values of that extra 210 rows.
The issue im having is that the numbers in these rows are not unique.
For example,
Column A contains the following numbers: 2,1,3,4,5,5,6,7
Column B contains the following numbers: 1,2,3,4,5,5,5,5,6,6,7,8
I want the outcome result to be: 5,5,6,8
I can't seem to wrap my head around a way to do this.
I have the two columns in a text file that im importing into excel. If there are better ways to do it outside of excel, I am open to it too.
With the Dynamic Array formula Filter:
=FILTER(B1:B12,COUNTIF(OFFSET(B1,0,,SEQUENCE(ROWS(B1:B12))),B1:B12)>COUNTIF(A:A,B1:B12))
Without FILTER:
Put this in the first cell and copy down:
=IFERROR(INDEX(B:B,AGGREGATE(15,7,ROW(B1:B12)/(COUNTIF(OFFSET(B1,0,,ROW(INDEX($ZZ:$ZZ,1):INDEX($ZZ:$ZZ,ROWS(B1:B12)))),B1:B12)>COUNTIF(A:A,B1:B12)),ROW($ZZ1))),"")
Try to follow these steps, supposing that Column A has less values than the Column B and the rows start at 1:
A. Create Column C.
In the cell C1 place the function: =COUNTIF(A:A;B1)
Copy this function to the rest of cells, for all items of Column B. So, cell C2 will have the function =COUNTIF(A:A;B2) and so on.
B. Create column D.
In the cell D1 place the function: =COUNTIF($B1:$B1;B1)
Copy this function to the rest of cells, for all items of Column B. So, cell D2 will have the function =COUNTIF($B$1:$B2;B2) and so on.
C. Create column E.
In the cell E1 place the function: =IF(D1<=C1,"Exists","Missing")
Copy this function to the rest of cells, for all items of Column B. So, cell E2 will have the function =IF(D2<=C2,"Exists","Missing") and so on.
D. Filter to show only the rows that Column E values are "Missing".
Of course you can combine all above 3 columns to one (e.g. in Column F), so these cells will have the functions:
F1: =IF(COUNTIF($B$1:$B1,B1)<=COUNTIF(A:A,B1),"Exists","Missing")
F2: =IF(COUNTIF($B$1:$B2,B2)<=COUNTIF(A:A,B2),"Exists","Missing")
and so on
Explanation:
In column C we count how many times the value of the respective cell
of Column B exist in the whole Column A.
In Column D we count how many times we have "met" this value in Column B so far.
In Column E we check if we have "met" the value more times that it exists in Column A. If indeed we have "met" it more times, then we mark the cell as "missing"
Tested with the example you provided and works okay.
I hope it helps!
Good luck!

How to lookup a value from another column and display Row number?

I'm setting up an excel file for the operators. They will scan the Barcode from the product and it will populate in one of the column of the excel sheet.
I have tried using LOOKUP formula in excel but it doesn't seem to be working right.
COL A : Data from Database
COL B : Data from Scanner
COL C: Row number
Find the value of Column B in Col A and populate the Row no. in Column C.
=LOOKUP(B5,A:A,ROW(A:A))
I have used this formula in every cell of the column C.
The row number don't populate accurately.
=MATCH(B5,A:A,0) should give you the rownumber. And if you wish to obtain the cell's address: =ADDRESS(MATCH(B5,A:A,0),1,4,1)
If you are using combined cells then you definiately want to use absolute ranges like =MATCH(B5,$A$5:$A$10,0)
Search B column in A column and get row back. You could use:
Note:
Do not forget to use IFNA in case of B does not included in A.
In my opinion there is no need to target whole range.
=IFNA(MATCH(B1,$A$1:$A$6,0)+ROW($A$1:$A$6)-1,"")
Results:

Count the cells in col A that have entries in col B

I am working on a table with thousands of entries. I am looking for a formula that will count all the records in the column A that have data in column B.
Some cells from column A could be merged and being represented by 2 entries in column B which are 2 cells. It is like one cell in column A have 2 cells in column B, being altogether one line. I hope I made myself understandable.
I tried to use like countif, but it's not the case I guess...
I have attached a little example in the below link.
Hope there is someone that could help me with that.
=SUMPRODUCT(--(A1:A5<>"")*--(B1:B5<>""))
The above counts the number of rows where A is not blank and B is not blank

Is there a way to delete cells if their value is contained in another column?

I have a spreadsheet with multiple columns with a few thousand rows and I would like to find the cells that are common across all columns. Is there a function that I can use to check if a cell value exists in a set of cells/column?
To find out if a value exist in all columns but in any row you can put this equation in the next open column and drag down:
=AND(MATCH(A1,B:B,0),MATCH(A1,C:C,0))
This assumes you have data in column A, B & C and the equation is in column D. now you can sort on column D for unique values.
Depending on your data type you might get an error. If that is the case try this:
=AND(IFERROR(MATCH(A1,B:B,0),FALSE),IFERROR(MATCH(A1,C:C,0),FALSE))

Sort row data into columns with same heading in excel 2010

Put simply, I need to sort row data for a specific range into the correct columns based on that columns heading. For example, if there are five columns labelled A through E, and data in the rows below ranging from A through E; I need all of the A's to be in the A column, all of the B's in the B column etc.
Example start data:
How it should look after the sort:
It also must be able to work with the possibility of having empty cells. For example; if the first example data had no B in row 3, the data must not shift over to the left so that C is in the B column etc.
Other info: not feasible to do by hand - over 450 rows.
It also must be able to work with the possibility of having empty cells.
Taking the above into consideration.
NON VBA WAY
Insert enough columns so that the data moves to the right
Next in the row one, duplicate the values from your data
Next in Cell A2 Put this formula
=IF(COUNTIF($H$2:$L$2,A1)>0,A1,"")
Copy the formula to the right
Next remove "$" from the table range and add it to the header in formula in Cell A2 so that we can copy the formula down. This is how it would look
=IF(COUNTIF(H2:L2,$A$1)>0,$A$1,"")
Similarly your B2 formula will look like this
=IF(COUNTIF(H2:L2,$B$1)>0,$B$1,"")
Change it for the rest
How highlight cells A2:E2 and copy the formula down.
Your final Sorted Data looks like this.
Copy columns A:E and do a paste special values on Col A:E itself so that the formulas change into values and then delete Cols H:L
