Matching Excel Columns - excel

Would really appreciate some help. Pretty basic problem. In column A I have SSN's, Column B I also have SSN's and in column C I have dates associated with the SSN's in Column B. The problem the 2 different SSN's columns don't match and I need them too. Problem 2: The dates in column C need to stay associated with the same socials in column b.

This is fairly simple.
Either in a new sheet or in separate columns from your original data, create create a column that represents the same column as A or the original SSN's, this can easily be done with a simple reference formula =A1 and autofilled down. You can do the same for the second column that is a copy of the first SSN.
For the third column just use a simple INDEXand MATCHformula like this:
=INDEX(C:C,MATCH(E1,B:B,0))
This formula I have the new data in Columns E-G with this formula in column G.
What this formula is doing is looking for the value of E1 within column B (looking for the value of the first SSN within the span of the column B). It will then grab the date value from column C associated with the found value in B. This will not work if multiple of the same SSN's are found within column B.
Note: You have to set the formatting of the formula cell as a Date

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!

Matching linked data in Excel in one column to another when columns are not equal

I apologize if this question has been asked before, but I have searched and cannot locate it.
Each cell in column B contains a specific (but not necessarily unique) value for each value in Column A. Column C contains all Column A cell data, but also contains additional data cells. I am attempting to create a new Column (D) for the Column B values to correspond with the Column A/B relationship. There will obviously be blank cells in Column D (for the rows where Column C contains data not located in Column A), but this is not an issue for me in this situation. Essentially, I want the A/B relationships to all be reflected in Columns C/D with blanks in the D rows where C has data not located in A.
Any help would be GREATLY appreciated.
In cell D1, do :
=iferror(index(b:b, match(c1, a:a, 0)),"")
Then drag downwards.
Idea/reference : I use index match function (a web search will explain it much better) to retrieve the column b value n fill it in column d. And put a blank "" if no match found. Pls share if it works/not.

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:

Adding a unique value to duplicate rows in Excel

I have column A containing number ID. Each row in column A is Unique.
I have column B containing City names. Each row In column B is unique.
I have column C with duplicated city names from Column B. Duplications are random. One city is duplicated 2 times and another 10 times and so on.
What I would like to achieve is to assign the number ID from column A to duplicates in column C. Each different duplicate should have number Id in a form A1+1.
Notice that Alexander in Column D has value from A2, along with all duplicates. Alma is next with ID 499. Those are manual entries of course.
Can anyone provide a formula to automate this?
I'm using Google Spreadsheets..
You would use INDEX/MATCH, put this in D2 and copy down:
=INDEX(A:A,MATCH(C2,B:B,0))
try this:
Clear data from column D.
Paste ArrayFormula into cell D2.
Here's the formula:
=ARRAYFORMULA(VLOOKUP(OFFSET(C2,,,COUNTA(C2:C)),{B2:B,A2:A},2,0))
I think I had to insert a column A with same values as Column C in order to get Vlookup to work, as I believe it indexes off of the 1st column always.

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))
