Formula For Extracting Duplicate Entries In A List
Apr 4, 2008
I need a formula (I'm not sure if its possible without using VB which I have found on another thread) that I can 'drag' down to the cell Bx (where x is variable) to extract unique entries in a list of values and then display them in a shorter, more concise list - like the 'Pick From List' function does but actually display these values in seperately in a column of cells.
Hope this is making sense.
So (hopefully) to elaborate:
A1:Ax = The list of values containing duplicates
B1:Bx = The list of only unique values from column A
I am trying to create a drop down list from a named range that has duplicate names listed. I cannot delete any of the duplicate rows. Is there an easy way to create the list with each name represented only once?
I have a name in Column A, and a number that goes with it in Column B. Some of the names on Column A are duplicates. I want to extract a new list that will add the values in Column B of all matching names on Column A, so that my list has only unique names and a total of the numbers in Column B.
I have a spreadsheet that needs to have a validation drop down list in three cells in every row (D, E, F). There are three items in the list, say, "One", "Two" and "Three".
My only problem is that there can only be one entry of "One" in each row.
I'm trying to remove duplicate entries from a list of names & addresses.
What I'm after is some VBA code which will examine row by row the 'post code' field and the 'Full name' field and highlight/delete duplicate entries.
Its best illustrated by an example
Full Name Address Postcode Mr C. Verougstraete 6 somone st, Leicester HY8 9YK Mrs R. Brazier 8 high st HY9 9LK Mr C. Verougstraete 6 somone st, HY8 9YK
The last record is obviously a duplicate of row 2 therefore will be removed.
I am trying to create a column to match duplicate information, primarily numbers, so I can delete the duplicate information. Using the Find option is too time consuming. I am pasteing the new info above the previous weeks info. Some years ago I used a formula that would "Match" a range and I believe it would copy the duplicate in the empty column but it's been so long I am not certain nor do I remeber the formula. I've tried using the filter feature and looked at previous post but I am not familiar enough to know how to decipher the info given.
How do I set up a custom validation formula to prevent duplicate enties?
For example I I've already enter the song name 19 and Paul Hardcastle (BandName), how do I set it up where I can not enter that combination again on a row?
I was wanting to use a custom CountIF function but I could not get it to work.
I have a long list of work items that is referenced by a unique 7 digit number. I need to create a formula to identify the specific work items that is being duplicated in the list and generate that number. Example is as follows
Work Item#
1234567 1234568 1234567 1234569 1234568
Based on the above list, I need to create a formula that generates all work items that is being duplicated.In the example above, the formula should generate the following work items:
I have been trying a number of different functions!
I have the following countif function that is searching a worksheet (Cases Closed) for the name John in Column O and excluding Solutions in column x. The problem I have is there are duplicates cases in Column C that are being counted two and three times.
Is there anyway to have the following function exclude duplicates records in Column C? Just count unique records in Column C?
I have sales rep data with column headings as Sales Rep, Sales Date, Sales Item Code and Customer ID. There are only 2 sales reps in the data, I'll call them Rep A and Rep B. I need to extract rows where Rep A and Rep B have made sales on the same day to the same customer (it doesn't matter what type of sales). I don't want to extract sales by only one rep, it must be both reps on the same day to the same customer. I have tried a pivot table but it identifies all sales. Can this be done?
I have 2 huge lists. One is " the Master list" which I have to extract items that are not already listed on the second list . I don't want to remove duplicate entries,I want to remove the duplicates completely. in both lists, so that I only have items that are not in the second list...
Basically I've made this up myself because what ill be working with has 100s if not 1000s of rows with many different product numbers that's quantities are different. What I've been able to do up to now is sort the spreadsheet by the product number so all the same rows are next to each other. My problem is however I need a speedy way of making these duplicate rows become one but add the total quantity basically everything in the left screenshot into the one on the right. What I've tried up to now is sorting them so there together and manually adding them up and putting them into one of the rows quantity, then delete the rest. takes to long. Another was to make a row underneath the rows I need into one but that takes more time than manually adding and deleting the rest.
I'm working on a employee evaluation form. I'm using a Pass/Fail system. I have a cell designated for PASS & one for FAIL. In these cells, I would put "YES" if they passed, "YES" if they failed that section. How can I prevent someone from mistakingly entering Yes in both cells?
I am trying to find a macro that will clear duplicate entries in a column of data, and then move to the next column and repeat the process until it gets to a blank column.
There are blank cells between entries in a column. I need to keep the data unsorted as the cells are linked to others in the row, therefore I dont want to delete the cells, just clear the contents.
I would like to check column B and if any of these values match values in column J hightlight the cell on the same row as the match on column E green. I don't know much about excel but this would be a tremendous help because i'm looking through quite a bit of data. I've tried using conditional formatting and i can't seem to get that to work for my needs. Let me know if you need anymore information.
I've generated a sheet where, based on the total run hours of a generator set using a given fuel type, we can determine which engine to run on what fuel when. The problem I've run into is that if more than one engine has the same runtime, the chart returns just the lowest numbered engine and eliminates the remaining engine(s). What I'm trying to do is make it so that when this occurs, the suggested engines show up in numerical order. For example instead of 1, 1, and 1 showing up on the chart, something like 1, 2, and 5 will show when they all have 0 run hours. I've attached my chart below with some engines having the same runtimes. RunOrder.xlsx
New here, I wanna do a "Prevent Duplicate Entries" into my column i try the following: http://www.mrexcel.com/articles/prev...duplicates.php http://www.theexceladdict.com/_t/t040818.htm
They all work well but if I'm using copy and paste It doesn't work! why is tat so? Second issue will be i'm wanna do prevent duplication for the whole column not just one cell.
I have a spreadsheet that has account numbers listed multiple times. I need to eliminate all of the duplicate entries...Is there a formula for this...?
=COUNTIF($A$1:$D$100,A1)=1 however I don't know how to change that to suit my needs (or even if it is at all possible to change it to suit my needs)
I will try my best to explain how my spreadsheet is set up as unfortunately I am at work and I can not use the method to show you the spreadsheet.
My spreadsheet: I already have Data Validation in use from a list that I created. I use the same validation list in Columns C, E, G, I, K-BA
I also use validation list in other cells, and it is OK if these are duplicated throughout the row.
The only cells that should not contain duplicate information are the ones from C, E, G, I, K-BA
Basically I want to stop someone accidentally chosing the same option from the list within the same ROW.
Just in case it makes any difference I should let you know that I have already had help from the forum regarding macros for this same spreadsheet, here is the macro that is currently running just in case it makes a difference if there is an answer to my current problem.
Option Compare Text 'A=a, B=b, ... Z=z Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Cell As Range Dim Rng1 As Range
On Error Resume Next Set Rng1 = ActiveSheet.Cells.SpecialCells(xlCellTypeFormulas, 1) On Error GoTo 0 If Rng1 Is Nothing Then Set Rng1 = Range(Target.Address).........................
there are unique entries like AU0896 etc. that are repeated in my list. my job is to find how many unique entries there are and add the count at the end so, basically if there are 6 AU0896 entries, then I must create a AU08966 value.
In my spreadsheet, on ( sheet A) I pick up a value to a range (O2:O22) from other worksheet (sheet B), the value is validated when a cell in the same range but other column (A2:A10) reach a specific criteria.
But in the same column if the criteria is typed again I gone a have the same value on range( O ), and I dont want that, because this value represents a total for a day, and is to be added to other cell.
I'm using this, to pick up the data Ex: (A2:A10) Criteria (O2:O10) value picked up
on SheetA, Sumif(sheetBA10:A40,A2,SheetBK10:K40)
How can I count only one of the values picked up from sheet B?
Got a workbook with 4 worksheets and sometimes we need to cut and paste a row from one worksheet to another, now thats easy now as we are all human and sometimes it gets copied and we have duplicate logs.
Now each sheet has usually not got that many rows in it, but that spreadsheet is getting sent to the highest people in the company and any mistakes look poor.
What i'm looking for is a way that i can highligh any rows that a duplicated in each worksheet. I can do it in each worksheet using conditional formatting with something like = COUNTIF($A8:$A$20,A8)>1. but don't know how to check that is not on any other worksheet. On every worksheet only need to check Col A for the duplicate information
Wihitn a large SS I have a column which has a number of entries that may include an amount of duplicate entries. Till now I have been using Sort and them manually deleting the duplicates is anyway that I can select just the Column and then without sorting go down and if a duplicate is found, then the duplicate would be deleted. Meant to say the dta is numeric.
I have a spreadsheet which has data in column A & B. I trying to do an if statement to state "YES" if data in both A and B has been duplicated. EG 111 in (A) & 222 in (B) are a PAIR, im need an if statemnet in Column (C) to say if this PAIR are duplicated in these two columns return "YES". I have tried THREE different methods to do acheive this which are in the attached document. The main issue I am having is the iff statement is returning yes for some of the number when thye are completely different. I have used concatenate, & and tried to multiply the two values to try to make it unique. I have an example of each in the separate tabs.
I'm trying to get data totals for multiple entries and haven't been able to figure out how to do this using a pivot table.
For example:
A B Ben 2 Bill 1 Jane 3 Bill 4 Dave 7 Jane 4
Would make it
Ben 2 Bill 5 Jane 7 etc.
this list is 3700 cells long.
Is there an easy macro or another way of doing this? I want to generate a list that gives all data totals but just lists each persons name once. I treid attaching the file but it wont let me! here is the link... [URL]
Now I want to create list C, a modified version of list B, which is made up of everybody in list B, EXCEPT for those people who are also present in list A (in this case, Jeff and Cindy).
So basically list C should look like this:
C:
fred@fred.com angus@angus.com chuck@chuck.com
What would be the fastest and most efficient way to create list C?
