Removing Duplicates From List Based On Latest Date?
Jan 6, 2014
I am working on a large data file (leasing file), that has many duplicates. The names on the file are duplicated due to the various variable costs associated with leasing. I need to remove the duplicates names based on the latest contract end date.
I am importing some data from a source which every time I just want to have latest revision of documents and I want it to be dynamic so that every time I import data the deletion would be automatic the data I import is something like this
DOC NO. DOC DEScription status
and as you see I have duplicate documents with different revisions and I want to have the latest last revision only.
I am working with a large spread sheet of people names and the courses that they have attended and what date they attended. The Sheet Identifies : ID No. Names, Courses, Date Attended, Due Date How can i remove all entries execpt for the last date for each qualification entered on each person?
I have data in the form of a table. For example a list of duplicate names, each of these names have a corresponding date (lease expiry date). The problem is that the duplicate names have varying dates. So the remove duplicates function does not work because i need to remove the duplicate names with the older dates. I want the latest dates to remain behind.
Data Currently: Solution should be: Sue1/3/2014Mike8/8/2014 Jay25/4/2013Sue1/3/2014 Jay25/4/2013Jay25/4/2013 Mike8/8/2014 Mike8/8/2014 Sue1/3/2014 Sue25/6/2012 Sue1/3/2014 Sue5/7/2012 Jay2/2/2011 Mike5/5/2010

I am using Excel 2013 on Windows 7. In the above example columns A & B is the given list to process, and Columns C & D contain the result I am trying to achieve. The major part of this that I am having trouble on combining, separating them with commas in another cell, and ignoring a duplicate value. You can see bill has two red values, but I only need it displayed once in column D.
I need a formula to do a partial text match on column B to find all rows that contain "825-CL-A", then sum column C for all applicable rows with the latest date. In this example the result should be "4.25 + 6.50 = 10.75". I'm using Excel 2003 for this project.
A B C 7/1/2012 0:00825-CL-A-41091-REG4.00 7/1/2012 0:00825-CL-A-41091-REG6.25 7/1/2013 0:00825-CL-A-41456-REG4.25 7/1/2013 0:00825-CL-A-41456-REG6.50 1/1/2014 0:00825-CL-A-41640-REG4.25 1/1/2014 0:00825-CL-A-41640-REG6.50 3/1/2014 0:00825-CL-E-41699-REG3.00 3/1/2014 0:00825-CL-E-41699-REG4.00
I am having rows of data, that i will be updating from time to time. I want excel to move the latest updated rows, in any column if updated, to move to the top, to easiy know that i updated those records. It should be that when i updated more rows than one, then the first updated cell would be in lower, in order, than the latest updated cells. I do not want any cumbersome vba. I want in formula or in conditional formatting. The row no may be total not limited to some rows.
Because, you naturally would have updated the 200 th record and would have saved. It saved as it is, so when you next opens it it is there, but how can i know that that is the last row of data i edited.
I'm on excel 2010 and I have a small group excel files I open everyday. Most of the files are static in name and location. I've got a macro created to open those files, which works fine with workbooks.open and the file path.
There are two report files I want to incorporate into my macro of workbooks to open. The files are created weekly and the files names have the following format: "Report Name (YYYY-MM-DD).xlsm". I don't want to use the file's last modified date because older files may get edited after the more recent ones are created. The files are also not always created on the same day, so the solution needs to be flexible enough to not refer to a specific day of the week or anything.
Macro open an excel file based on the latest date found in filename.
The attached file (a copy of my main one) has a list of our engineers, and what stock they carry. The stock parts are the 64, 65, 66... numbers.
I need to create a list from this (as underneath the main table), for all instances where there is a 'Y' in the columns next to each engineer. So if an engineer has 3x pieces of stock, they need to appear in the list 3x times. If they have 1x piece of stock, they appear in the list once.
I have a list of Dates in Col. A Column B contains both numerical and text values.
I need to define a value in column B, and create a list of the dates that these occured on, on another sheet. Auto filter doesn't work because there are several different columns. If I try to use it I also get the values in the other columns.
I am trying to organize some meteorological data for a project and I ran into a wall, basically I have 3 columns in one there is the date, in one the hour and in the third one the temperature the issue is that in the hour section i have the hour 12:00 that repeats its self , and this goes for the hole year , pretty much every day i have the hour 12:00 that repeats twice , so select for every Monday , Tuesday etc only certain hours.
I have list of data references about 60000 of them but some are duplicated. I have used advanced filted then unique records only. So now i have just the unique records showing now. How do i copy the accounts that is just unique into a new worksheet? I tried copying it but its copying everything. I even tried using paste value but still copying everything?
I want to retain the row with maximum elements(row 2 in above eg.).
Result should be:
Name Col-1 Col-2 Col-3 Col-4 abc 1 2 3 4
Currently I am doing this manually, by adding countA at the end of each row, then arranging them in descending order. That will make sure that the row with more data comes first n hence gets retained, while other rows gets deleted. Can this be done using Macro?
Below macro just deletes the rows,
Public Sub DeleteDuplicateRows() Dim R As Long Dim N As Long Dim V As Variant Dim Rng As Range
On Error GoTo EndMacro Application.ScreenUpdating = False
I'm adding data from a report into a spread sheet and some of it will be duplicated. I want to remove the duplicate data, but is there a way to differentiate between the older (and more complete) data and the newer data? In other words, how do I get rid of the duplicate while keeping the one I want to keep?
I was considering the advanced filter, but if I create too many columns of criteria will it be seen as unique?
I'm trying to find out the rule for de-duplicating data. I am removing duplicates based on an identification number in a data set of about 6000 records, including the duplicates (some records appear about 4 times). Due to the nature of the data I'm working with, there are only a handful of records that are "true" duplicates, i.e. some of the records appear 4 times but there is a difference in terms of location, etc and some are true duplicates in that there is no difference.
I need to know how Excel removes duplicates - does it only keep the first line that it finds for that identification number? Also, is there a way that I could create a rule for it to keep the record with the highest rate for example?
i'm trying to remove duplicates from a worksheet containing customer contact info. the sheet has 9 columns with headings, and the duplicates appear in the last name and phone number column. (the sheet contains no outlines/groups/subtotals.)
i want to remove entries that contain the same last name AND phone number, however when i go to DATA>DATA TOOLS>REMOVE DUPLICATES, and specify the columns i want to remove duplicates from, it keeps deleting an entry that has the same last name, but not the same phone number.
i even tried removing duplicates from only the phone number column, and it still removes the phone number for the entry that has a duplicated last name, even though the phone numbers are different.
I have about 20k records with dealer codes and brands listed. I need to be able to see the duplicates from the dealer numbers and brands. Is there a formula that can be used to locate them and see them before removing them?
Can someone look at the sheet sample? I am trying to turn duplicates into a zero like Ive done in record 1 so that the same tax bill is not counted twice. The records are in rows and if I do a transpose and try to do it by hand it will take forever cause I have hundreds of records.
I incorporated more codes to the ones that were just solved from this board, but how can I make the active cell stay on A1 of sheet "hypo_tax_dropdown"? Also, I obtained the codes for removing the duplicates from macro recording, will these codes work on any machine? I noticed that it doesn't have worksheet.function
Sub Macro1() Dim X As Long Sheets("Hypo_tax").Select
I have several fields in a row that contain names of files e.g. 123.xlsx. Some fields will contain file names that will be duplicates of each other and some will be blank entries (although the blank entries can be changed to a value such as 'n/a' or 'no' etc if required).
I require only the non duplicate values to appear in the final cell, each separated with ';'.
My data is in row 2 of a spreadsheet and in every other column (A,C,E,G,I,K,M...for 45 instances in total).
I have used the following formula to identify the unique values (example below for the first four cells): =A2&IF(C2=A2,"",","&C2)&IF(OR(E2=A2,E2=C2),"",","&E2)&IF(OR(G2=A2,G2=C2,G2=E2),"",","&G2)
This works well and if there are several blank entries then I use a SUBSTITUTE function to change the multiple ',,,,' to a single ';'. So I only see the unique file names in the final cell, separated with ';'.
However, the above formula becomes longer and longer when each cell is added to it. I have over 40 cells that need to be added and I wondered if there was a better way of doing this?
