Subsequent Duplicate Records

Mar 30, 2009

I have a single-column list. The column header is 'ID'... records within this column repeat sometimes (this is ok). I need a worksheet function that will allow me to mark the second, third, or fourth duplicate, but leave the first duplicate alone or unmarked. I have searched the Web and this forum, and came up empty. If this cannot be done with a worksheet function, then VBA is welcome. No ColorIndex.

Removal Of Subsequent Duplicate Values In Time Series Of Data?

May 22, 2014

I'm having some problems with the removal of duplicate values in a time series. The time series consist of stock data for about 10000 firms, but about 3000 of these firms died(delisted) before the end of the sample. The database I used to extract these data, however, does not remove the firm values from the sample, but keeps the last known value of the firm for the remainder of the time. Therefore, I need to remove these duplicate values, but only if they are sequential. Furthermore, normally if you remove duplicate values, excel will delete the cell and shift the data upwards, since it's a time-series I would rather have excel just blanking out the cell instead of removing it.

I've looked at normal solutions, like using the countif functionallity in excel, but this is not feasible because of the size of the worksheet, also, it does remove non-sequential duplicate values as well.

summary:

- Want to remove duplicate values, but only sequential values.( It's possible firm value is the same somewhere in the time period)

- The cells should be blanked out instead of deleted.

Find Duplicate Records Based On Multiple Columns But Keep Records

Aug 10, 2014

I have a range of columns i.e. 23 columns (i.e. B through X). Someone can write records in these columns (starting from B21).

Duplicates are considered the rows with similar data in columns 3 and 11. I know about the removeduplicate method and works really well but i want the duplicates not to be removed. Instead another column shall be checked for date of entry (user will entry date in format dd/mm/yyyy). The newest entry will change the value of the cell in column 4 (islatest column)to TRUE while all other records will be FALSE. This will work with the filtering of data on a pivot table on another worksheet.

Sumif Without Duplicate Records

May 8, 2008

In Column A, is gender: male/female
In Column B, is name: Bob, Jon, Mary, etc
In Column C, is salary: $40, $30, $20, etc.

In column B, there will be instances where a name might appear more than once. I want to be able to do a sumif formula of Column A and Column C, but not include any records where a name in column B is listed more than once. Is there a way to do this?

1 Male Bob $50
2 Female Jane $30
3 Female Kate $20
4 Male Mike $30
5 Male Bob $50

So if I wanted to sum all male salaries above, it would be $80, not $130.

Keep Only Duplicate Records And Remove The Rest

Dec 12, 2012

My spreadsheet has more than 200 columns and 5000 rows of data and blanks. When I select all columns and rows and remove the duplicates, 6 records are removed. I need to only keep and be able to identify those 6 records. I could use something like =IF(COUNTIF($A$2:A2,A2)=1,1,0) if I had only few columns that would identify dups but since there are so many columns it would be prodigious job to create one formula for each column and filter through 200.

Duplicate Check On Export Of Records

Dec 20, 2008

I have a spreadsheet that will export records when I "click" a button, to a spreadsheet on a network drive.

I would like to attach some code that will check to see if a duplicate record is going to be written to the network drive, and if so, alert the user that they are about to create a duplicate . If it is a duplicate, give the user the option to overwrite the existing record.

Ex. I export the results for account 12345.....Account 12345 is now written to an outside sheet.

User2 logs in and works with customer 12345, w/out knowing that someone has already worked with this account, presses the export button.....This is the trigger point for what I want to happen. At this point when it locates a dupe in the outside spreadsheet it will prompt the user too make some chouces .

find attached the code I would like to attach this to...

Consolidate Duplicate Fields / Records?

Apr 12, 2013

I have spent the last couple hours compiling a large amount of data. I have a list of websites, each have a number of visits and transactions. The list is many thousands strong so i have a huge amount of data to work with but there are a lot of duplicate sites. See below, I have taken a snapshot of some of it:

I've highlighted a duplicate example.

Would it be possible across the entire data set to sum all of the duplicate rows into one. So, for the 3 shown, to be reduced to one row with 228 visits and 2 transactions?

And to do it quickly? As I could go through them manually but I don't have to time to go through 10,000 rows.

Finding Duplicate Records With Condition

Aug 20, 2008

Wondering if there is a way, script-wise or formula-wise that will look through a table and find duplicates but not just any duplicates, it has to match a certain criteria.

For example, I have a column for UPC and Vendor#. I have my table sorted by vendor (all 159 of them in one table) I want to find out whether a UPC appears more than once for a vendor.

UPC --- Vendor
11254 135
11251 135
11251 135
11254 9345
11251 9345

Here, as you can see, UPC 11251 appeared more than once for vendor 135. Can this be done through conditional formatting ? or a script?

Concatenating Data From Multiple Duplicate Records

Sep 15, 2006

I have an excel spreadsheet that should have one record for each artifact in a museum collection. The problem is that the museum has consolidated this information from several different sources into one spreadsheet and now there are many duplicate records. They want all the duplicate records removed so that there is just one record for each artifact, BUT there may be different pieces of information in each of the duplicate records. So I want to do the following:

- sort records based on Accession Number (column A)
- find duplicate Accession Number records
- determine which fields (columns) within a duplicate record are unique and concatenate those entries into one master record for each Accession Number
- delete the duplicate Accession Number records

In the attached sample sheet, for Accession Number 66-1-100, we have 6 duplicate records. In the columns, we have information which in some of the records is duplicated, in some it is unique and in some it is missing completely. The museum wants just one master record for each Accession Number and they want all the data from the duplicate records concatenated into one and all the duplicates and blanks discarded.

What I've done so far:............

How To Prevent Duplicate Records From Being Entered On Recording Sheet

Feb 9, 2013

I have a created recording sheet (attached) for the purpose of recording moths. I send this sheet out to those recorders who live in my county and at the end of the year they send the filled in sheet back to me. Over time I have put safeguards onto the sheet to ensure that I get the cleanest data returned to me. However, there is still one area which is giving me problems - users entering duplicate records.

Some formula which will stop recorders from entering those duplicate records. There are many columns on the sheet which recorders have to fill in with information, but as far as the duplicate records are concerned it is where the same information is entered into columns C, F and J that I'm having a problem with. It would be great if, when the same information was entered in these columns that the affected cells were highlighted in some way and if an error message appeared saying 'Duplicate record, either delete or alter grid reference'

I have entered two test duplicate record on the 'macro moths' sheet of the attached file : Test Recording sheet.xls‎

Unique Row Headers / Values To Subsequent Columns

Mar 9, 2014

I have a table similar to the table on the left, and I need to convert it to something like what is on the right. Ultimately I will concatenate the numbers in the table on the right too with commas between, so if for some reason it's easier to go straight to that, that's an option.

So in the example below, states will be listed multiple times with a unique number next to it each time. The state may be listed up to say ten times or as little as one. Each time it is listed, it will have a different number next to it. I need to reformat this into one where each state is only listed once, and each possible number is next to it in one row.

Make Cell Result Copy Itself Into Subsequent Cells X Number Of Times?

May 9, 2013

Say I have (cell A1) 10 salespeople and they each sell a (A2) $100/month membership, so I have (A3) $1,000 monthly revenue.

(A4) is an assumption about how many months the average person will stay a member.

So if A4 = 6, (6 month membership assumption) how would I get Excel to output $1,000 (the result from A3) into cells B3 through B8

but then for instance if A4 = 3 (3 month membership assumption) it would only output the the $1,000 result from A3 into cells B3 through B5

So like A1 through A4 of...

10
$100
$1,000
6

would output $1,000 into B3 through B8

but

10
$100
$1,000
3

would output $1,000 only to B3 to B5
