Finding Duplicates (sort Of)

Jan 28, 2010

I have a spreadsheet with 7000 lines exported from a database. I'm looking for lines that exist with an @@2 that don't have a corresponding @@1. Let me explain.

SV10000000@@1
SV10000000@@2
SV10101000@@2

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 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.

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.

Count Duplicates In A Cell Then Rank Them And Sort Them

Sep 13, 2006

I would like to have the duplicate numbers in position one ( cell D9:D18), position two (cell E9:E18) and position three (cell F9:18) all counted and then ranked based upon date range in column A.

The number order of precendence is 0-9 with zero being the lowest.

Column (I9:I18) counts the duplicates, draws and no draws of digits 0-9. Column (J9:J18) converts results from column I9:18 into a percent.

I need to add a sort button at the bottom of position 1 (columns H & I 22), position 2 (columns L & M 22) and position 3 (columns P & Q 22)

When the sort button is selected it will sort the data by # of repeats, draws, and no draws as illustrated in (columns I, M & Q) or sort data by Position number from 0-9 as illustrated in (columns H) which will then show data of repeats and percentages out of rank order, because it is in order of number precedence.

Last but not least a graphic bar chart that shows the results ranked highest to lowest from when the sort button is selected with the number at the top of the bar colored black. Bar graph colors to be: top 3 red, middle 4 yellow and bottom 3 blue. This should show a vertical cascade effect.

Merge, Sort & Eliminate Close Duplicates

Jul 20, 2007

I am attaching a file with an example of a spreadsheet that I am trying to sort out. In this example I have 3 samples (I could have many more). Each sample has 8 columns associated with it (N, M, I, F, S, MS, KM and KD). The length of the dataset is different for each sample. The MS column is the same as M but contains a few zeroes. What I am trying to do is:

1) generate one column (MSA) containing only unique values (no zeroes) from columns MS1, MS2 and MS3. The unique values should be selected within a specified tolerance (for example, 0.001, which makes 52.00706 from MS1 and 52.00701 from MS2 duplicate values although they are not exactly the same)

2) generate 3 columns ( named SS1, SS2 and SS3) with sorted columns S1, S2, and S3 so that for each value of MS in column MSA each of the three columns will list the corresponding value of S1, S2 and S3 (zero if there is no corresponding value)

Finding Auto-Sort Macro From MIN Calculation

Apr 21, 2014

What I want to do is place a lap time into 2 columns (representing each lap), then excel chooses the lowest number in the two columns on the same row, paste it into another column, and then automatically sort, while keeping the first column static for 1, 2, 3, 4, 5 etc

So what I want is

Column A | Column B | Column C | Column D | Column E
1 | Driver Name | 14.004 | 14.102 | 14.004

I want Column A to remain in tact, never changing, 1-50. I want Column E to hold the fastest lap time calculated from C and D. Then I want excel to automatically sort Column E from lowest to highest, while keeping Column B with a specific driver name in line with their respective lap times. Column A is not a 100% solid requirement, but auto sorting Column E after it's calculated the minimum value of C and D is.

Sort SCADA Data And Finding MAX And MIN Values?

Apr 27, 2013

I have a small challenge with the following parameter

2 columns of data, the first A contains sets of calendar dates:
A1 27-4-2013
A2 27-4-2013
A3 27-4-2013
A4 28-4-2013
A5 28-4-2013
Op to 5000 lines but normally around 140 of them for each date in April 2013
Colum B contains wind speed data from a met tower
B1 15.0
B2 5.3
B3 7.9
B4 3.2
B5 32.4

What I need to find are the Highest, Lowest and Average wind speed for a specific date.

I have a NOW -1 function in field C1 I would like to use as the parameter to search for in column A so I get the last full calendar days full data set (10min values), so writing it up it sounds something like this: Look in column A line 1:5000 and if you find any date the same as in C1 then move the content of B to a new separate column D line 1:140 and when all 140 lines are extracted for the specific date then find the Highest, Lowest and Average wind speed between those extracted data.

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.

Duplicates Finding Entries In Column A Which Match Any Of Column C Entries

May 7, 2014

What I need to do is sort certain entries in longer list (column A, it is in .csv format and needs to be in it so coordinates and names and ID, all sorted with commas) and I have another list (column C) which is shorter list of certain IDs. I googled and tried and got some results for the basic structure but the fuction seems to fail. It doesn't matter how I get that third list done, but there is only one criteria: since the list in column A is really long and those entries need to keep the .csv formatting, the function should copy that info what is in the matching cells.

Let me try to put it simple: .csv cells from column A that have matching ID from column C should be copied to column B (or N).

the function I'm working with right now is

=IF(ISERROR(FIND($C:$C; A1))=TRUE;"0";A1)

Pivot Table To Not Count Duplicates - But Show Duplicates When Click Into It

Aug 24, 2011

In short, I would like a pivot table to only count unique values, but when I click into the pivot I would like to show all instances of that value. For example:

I have a table of data that I am creating a pivot table from. There are fields for Customer ID, Task Name, Age, and Notes. There will be multiple records for a single Customer ID each time it has new notes.

I would like to create a pivot table that has Task Name in the Row Labels, Age in the Column Labels, and count of Customer ID in the Values, so that, for example, I can see how many accounts have been in the Design task for 2 days. However, when I do this it counts each record, but I would like it to count each unique Customer ID. Also, when I click into the pivot, instead of pulling up one line per Customer ID, I would like it to pull up each instance of Customer IDs in that Task Name/Age combination (similar to doing a DISTINCT in SQL).

Count Duplicates And Duplicates With Suffix As One Instance

Mar 23, 2014

I have a list of isometric drawing numbers ending with a [underscore]weld number e.g. 1692-SG-0040-04_05.

Some welds are repaired--in that scenario the amended weld number will be 1692-SG-0040-04_05R1, and even 1692-SG-0040-04_05R2 if repaired for a second time.

On occasion a weld may be cut out entirely and a new weld done. The weld number for that will be 6317-FG-1690-02_06C1.

And here's a wrinkle I've just verified...a cut weld may also be repaired so the weld number will look like 1698-SG-0077-01_04C1R1.

Is there a formula to count these as one weld:
1692-SG-0040-04_05
1692-SG-0040-04_05R1
1692-SG-0040-04_05R2

This as one weld:
6317-FG-1690-02_06
6317-FG-1690-02_06C1
6317-FG-1690-02_06C2

...and this as one weld:
1698-SG-0077-01_04
1698-SG-0077-01_04C1
1698-SG-0077-01_04C1R1
