Finding Duplicates Between 2 Rows ...

Jun 25, 2008

Just wondering if anyone has a macro, or formula that would allow me to find out (and possibly highlight), when any value in column A is equal to any value in column B. Im dealing with about 2000 rows so its almost impossible to complete manually.

Sorry the heading is supposed to read need help finding duplicates between 2 COLUMNS

Finding Max Value In Duplicates

Jul 22, 2009

I have data that has about 10 duplicate values (UTC Time) in one column and another column with number values (depth ft) that vary. I need to obtain the maximum (highest) value in the depth column and remove the other duplicates to filter out the low values. So for the data example below for UTC 15:56:28 I only want the 5.7 row, for 15:56:29 I want5.3 row and so on. I can attach the sheet. - this is a huuge dataset so manual filtering wont work. Data is from a sonar that gives 10 depth readings per second - I only need one depth tat is the highest value.

IDUTCDepth (FT)
115:56:284.3
215:56:284.4
315:56:285
415:56:285.4
515:56:285.7
615:56:285.5
715:56:285.6..........

Finding Duplicates ...

Oct 3, 2009

I have a workbook that I want to find if I have any duplicate numbers in a specific area.

The area of cells that I am checking is C3 through AO70

I am checking for numbers between 95 and 800. These are all ID# of individuals and not all the numbers between 95 and 800 are used. IE: 97 through 100 are not used ect.

I have already written a macro that does something else and I can use it to check each number as it comes up. However, once the number comes up I don't know how to use it to check the area.

If I can check all the area at one time to find duplicates it would be easier.

I do not know how to do either way but I can adapt my macro to whatever way is possible.

Finding Duplicates With Condition

way to wrap or format anything in this post. I dont think the text I put here is code, but I want to be sure, after receiving a moderators infraction for failing to properly wrap code in a previous post.

Now:

I have a wks in which the first column is a list account #'s and the folowing columns are specifics of transactions or interactions.

Lets say it is a movie rental customer list that lists each rental, and column "A" is the customer number, column "B" declares if it was returned late.

I need to compile a list of "all" rentals by customers who have "EVER" had a "late return" or a "YES" in column "B".

I need to find all account records/rows of accounts that at any time had a "YES" in column "B" even if the some or many of that customers rentals/entries have "NO" in column "B"

Finding Duplicates Out Of Millions

Oct 22, 2009

I have to scrub files of 20,000 phones numbers against a file of several million phone numbers on the national do not call list.

On sheet one I have all 20,0000 phone number and then on sheet two in 5 columns I have roughly 2 million phone numbers. I need to know if any of the 20,000 phone numbers are in the 2 million on sheet two.

Right now I am simply using a vlookup formula but it is taking a very long time to update all of the fields.

I want to keep the first two lines because there is an @@1 associated with an @@2. I'm looking to single out and delete lines that have @@2 that don't have a corresponding @@1 associated with it.

Finding Duplicates Adding Them To Another Sheet

Apr 1, 2009

Hello everyone....

I have a project where I need items for different boxes.

i have 20 boxes that need the same amount of items. However, when I came towards the end, i ran out of items.
For example

BOX A IS MISSING
ITEM 1 AND 2

BOX B IS MISSING
ITEM 2 AND 5

BOX C IS MISSING
ITEM 1 AND 5

I have all in a spreadsheet all the items that are missing per box. Here comes the main question....
How do I program my spreadsheet find the items that are missing in each box and summarize in another sheet?

The summary I am looking for is....

ITEM 1 - 5 (MISSING)
ITEM 2 - 9 (MISSING)
and so on...

I started doing the code, but I haven't got too far.

Finding Character Duplicates In Two Lists

Jul 19, 2012

I have two lists of numbers.

The first list contains site numbers of people who havent responded to me.

The second list is the master list of site numbers along with a column showing the date they responded.

Now, a site number is built like this:

123456/0001
123456/0002

So it is possible for the same 6 digits to appear more than once in the master list.

What I need to do is to compare the first 6 digits in the non responder list against the master list, because some sites, like the example above, may have more than one '0001' tag and so if they have responded to me from site '0002' I dont want to spam their other sites with emails.

I've tried using match and various formulas I've found from google etc, but nothing seems to work!

The goal of this is to get a list of non respondents that have not responded from any of their sites listed in the master list.

Non Responses

Master List
Date of Response

203289/0001

201162/0003
06/06/12

Finding Duplicates And Keeping Them With Totals?

Apr 8, 2013

I have a database with ~18000 rows and 29 columns. I would like to filter the data by duplicates in one column, based on total, but keep the remaining data in the row. For example: I have account numbers listed in one column, often duplicates. I can get the total in a pivot table no problem, but need the other data associated with that account. I do not need to see all accounts, only duplicates for accounts listed say greater than 5 times. The data in columns B+ are important.

I have a HUGE vlookup I created to paste in the pivot table data (account numbers and totals) to run a look-up based on those numbers, but I see that running into problems when you run 4k+ look-ups.

I want to see accounts listed only 5+ times, include that total (as in a pivot table) and the remaining 28 columns. I have tried to run this in a pivot table completely, but still too much data to process (plus all the subtotals that I have to keep removing).

Finding Duplicates Using Countif Or Similar

Jan 13, 2014

I have over 400 thousand rows in my data-set and I'm trying to find duplicates using a countif or similar formula. Let's say I have the following:

Blue
Yellow
Green
Blue
Blue
Yellow
Pink

I need the formula to increment the count. So for example, the first time Blue appears, it equals 1, the second it appears, it equals 2, third time is 3 and so on.

And, I need it to actually work with 400 thousand rows. I have tried using the following formulas without success as Excel keeps crashing:

=IF((COUNTIF(T:T,$T2)>1),COUNTIF(T:T,$T2),"")=IF(COUNTIF(T:T,T2)>1,2,1)

That second one equals "2" if there's more than 1, which will work for me as well. Better would be if it increments though.

The purpose of having a count is so that I can pivot the data, then filter out all the "1"s and report on it. Therefore I can't use conditional formatting, or simply using Excels Remove Duplicates feature. I need the same data-set for other pivots and charts.

Finding Duplicates - Variation On Previous Threads

Jul 9, 2013

I have a list of text values in column X. I need to come up with a formula in column Y.

X
Y (RESULTS OF REQUIRED FORMULA)
Comment
1
HAT
1
First HAT in column
2

[Code]....

I can't play about with the natural order of the spreadsheet, so there's no chance I can re-sort the data into column X and (easily) identify the duplicates that way. So, it could be that the duplicated value(s) will appear in any cell within that column.

I need to identify whether the item is a duplicate in the unsorted list. Ideally, the first entry of a set of duplicates will be given 1, then the subsequent duplicates themselves given a 0 (zero). It's to subsequently do some counts on.

I guess that as long as the one of the entries in the duplicates is marked with a 1, while the others are 0 (zero), that's all that's important.

Vlookup - Finding Additional Values From Duplicates Using Additional Column

Jan 29, 2014

I am using a spreadsheet as a score sheet for a competition. One of the columns is the student's GPA. After entering all the scores there are duplicate final scores. I need a way to have it look at the final score and then use the GPA so that it will not put a duplicate value in the final column.

al Column N is the Total Column, Column O has the Names that correspond to the Total Column. Currently I am taking this total and putting it into Column Q (High Scores) in high to low order. Column R should have the names that match the scores. But with duplicate scores, it is only putting the first name associated with the score. I would like to use the GPA as a final determining factor for the duplicate scores. The higher GPA would come before a lower GPA. I have tried to put an additional column to bring the GPA over to correspond with the High Scores Column, but could not get it to work.There are actually more names for the competition and the top 10 will be moved to a different sheet and further judged. I have attached a sample with the exact formulas that I am using.

Delete Duplicates (18k Rows)

Dec 24, 2009

I have a list of 18k rows, and about 7.5k are known duplicates. The delete duplicates button will not delete the duplicates (except it keeps returning 41 duplicates for an unknown reason, but there definitely thousands more it is missing). I tried the remove duplicates button, advance sort, coloring cells, and some macros. The list is the combination of two lists, one older one just compiled, I was able to seamlessly delete dups in another list.

Find And Hide Rows With Duplicates

Aug 28, 2009

I want to search a worksheet for rows that share the same value in two columns (columns C and E). See the attached excel file.

I have highlighted in yellow some rows that have duplicate values in row C and E.
So in this case rows 14 and 19 will be hidden but rows 13 and 17 will still be visible.

Note that this must work properly reguardless of how the data is sorted.

In other words, there can never be more than one row that has the exact same value for both column C and E.

Deleting Duplicates In Range Of Rows?

Mar 22, 2013

I have the following problem within Excel. I have a dataset which contains duplicate values within a column(lets say A). I need to delete these duplicates in column A for a range of rows, where the range of the rows is based on column B. So for a given value in column B, lets say 5 which is 6 rows long all beneath each other, I need to delete the duplicates in column A.

A B
1 2234
4 2234
5 2234
4 2234
2 2234
3 2234
5 2234
5 2657
8 2657
9 2657
10 2657
8 2657
9 2657
2 2657

So above the red numbers need to be removed, automatically, since we have about 8000 rows in our dataset.

Delete Duplicates (3705 Rows)

I have a sheet of Data containing 3705 rows. It has plenty of duplicates. Column A is where is located the identification. I need to delete the rows that are duplicated, in order to have only one row for each identification number. I tried to create my own VBA macro to do so, but it seems it doesn't delete all the duplicated rows and it seems to even delete unique rows.

Sub Duplicates()
Dim lstRw As Long
Dim i As Long
Dim j As Long
Dim m As Long
m = 1
Dim Compteur As Long
Compteur = 0
Application. ScreenUpdating = False
Let lstRw = Sheets("UE"). Range("A65536").End(xlUp).Row
For i = 2 To lstRw
'With Worksheets("UE")
SumNumber = Range("A" & i).Value.....................
