Find And Remove Identical Entries In A List
Feb 13, 2007
I regularly have to add a few new lines to what is in fact a very simple data base I've had running for a long time in Excel. About 1200 lines now, one line per person. I add a dozen or so lines (i.e. people) at a time in a different colour.
When I re-sort the whole thing I run my eye down the list to spot partial double (i.e. duplicate) entries (the new ones in their own colour helps). Then I delete the double entries one by one. Pretty stoooopid, in'it?
How can I do this better, faster and more accurately with Excel to find just two duplicated data ( NAME and ID NUMBER) in a person's line (there are 15 columns altogether)? Or: Where and what can I search for (I've just spent nearly an hour trying to find an answer by myself, but don't really know what to search for)?

I have over 2000 rows with 20 columns and i need to find and remove identical rows. I can do a match with MATCH() by concatenating the columns and comparing them as a whole but i need to apply this to the whole table and i need it to remove all the duplicate rows it finds.

Ok, so lets say i have one list of names (cell:value)
A1:Value 1
A2:Value 2
....
An:Value n
and create a new list
F1:Value 1
F2:Value 2
....
Fn:Value n
I want to have a list nearby and i'd like somehow for a function that will remove entries that already exist on the first list.

I have a list in Row A that has duplicates. I want to be able to delete both entries (itself and the duplicate). When done I want the list to display only be entries that are unique or better said any entries that never had a duplicate.

I have a large data set which contains four coloumns: Supplier, Supplier number, order number, and date/time of delivery. The date/time coloumn is formatted as YYYY-MM-DD HH:MM with a 24h time notation. What i want to do is to find deliveries that occurs within 1 hour and that are from the same supplier. So i basically want to group (?) the data with regards to the suppliers and then, within these subsets, check for date/time entries that occurs within 1 hour from each others by "reading" each date entry and compare it to the following one(s) (and maybe stop comparing when the 1 hour interval is passed)?
Furthermore, even if this one might be very hard, it would be good if i could make sure that the entries that are "tagged" as within a 1 hour interval, wont be used as basis for a new interval or be included in other intervals.
The result i am after would be number of 1 hour intervals for each supplier and the number of entries in each interval.
Below is an example from the date/time coloumn:
12-03-08 15:32
12-03-08 15:33 ... Interval with 2 entries
12-03-12 14:54
12-03-28 11:57
12-04-16 09:10
12-05-07 13:41
12-05-07 13:46 ... Interval with 2 entries
12-05-28 11:55
12-05-28 12:00
12-06-04 12:01 ... Interval with 2 entries
12-06-04 12:09
12-06-11 08:30
12-06-11 08:31
12-06-11 08:59 ... Interval with 3 entries
12-07-02 11:10

I have scoured the net for the following and have not been able to find a solution. I have found variations but not something specific for the use needed here.
I have attached a file with sample data which has the following format.
Column 1 = vehicle model (in this example golf, jetta, but there will be over 100 choices)
Column 2 = vehicle package option for specified vehicle model (automatic transmission, manual transmission, automatic transmission with air conditioning, etc...)
Column 3 = vehicle colour available for vehicle package option
Please note that Column 2 values for 'golf' are different than values available for 'jetta' (in the sample data I have blocked out common values with the same colour for quick and easy identification)
Also please note that Column 3 values of colour options vary for each 'vehicle package option'.
The behaviour that would be ideal is to have 3 drop down menus. The first drop down menu will allow selection from column 1 and will show each model only one time and repeated values will not be shown. The second drop down menu will only show the options available based on the selection in the first drop down menu. Likewise, the third drop down menu will show the colour options available based on the selection in the second drop down menu.
Since my data will involve hundreds of unique values in column 1 with plenty more added over time, it seems that the format of the data and the way it is laid out in the attached sample is the easiest way to organize it. It is perhaps also the easiest way to include new data without a lot of reprogramming.

I have an input sheet with 3 columns: Currency pair, Tenors, and Value.
Like this:
EURUSD 1m 3
EURUSD 3m 0
EURUSD 1y 5
GBPUSD 1w 2
GBPUSD 1m 9
GBPUSD 2m 1
etc etc for about 100+ rows.
This input is exported from a system we have and may vary in length and values from time to time.
What I want to do is pull all the data for specific currency pairs (probably for 5 of the 10+ currency pairs it displays) onto another worksheet. And for each tenor for that currency pair, i want to perform 10-20 lines of analysis on the next sheet.
So, if GBPUSD was a currency pair I was interested in, I would need 10-20 lines for GBPUSD 1w, 10-20 lines for GBPUSD 1m, 10-20 lines for GBPUSD 2m, etc.
How can I pull this? While maintaining flexibility so if the tenors, currencies, and # of lines change?

I’m putting together a blackjack odds calculator. I could use some help with a formula. If I have an A,7 (ace low) it needs to return a 0 (or false) for a “Possible Hand” because further down the column A,7 (ace hi) has a true “End Hand Total”
I was going to use an IF and a VLOOKUP (looking lower on the column), but then I cannot sort the column. Is there a formula that will find the hand and check for true 2 columns over from identical hand. There are 169 starting hand combinations. The attached worksheet only has 31 – for simplification.

Is it possible to find duplicate rows that are not EXACT identical. Conditional formatting can find duplicate rows but they must be identical exactly(ofcourse)(even extra SPACE,COMMA,DOT wont find duplicates)
I have name and address(street address) columns. I don not want my invitation cards or mails go to same address twice.
As you can see in the file ..all 5 records belong to same address.(address entered in diff styles,some comma,space extra..etc) 4 and 5 are Son and Wife of 1st person. Row 5 and 6 have same text but one extra space in 5th row makes it unique so i need to eliminate such records with same address So can i set some formula so that duplicate rows will be highlighted if any 3-4 words match ?

I have several sheets with tables that need to contain one identical common column called "product name" while all the other columns are different on each table. The issue is that this list in the "product name" column changes by adding, removing and even name edits and currently I need to edit each every table for each change. How can I only have one uniform list to modify that is represented on all these tables that updates.
I have tried a master list with links but causes issues when a product name row is deleted in the master it does not delete the row in the others as well as adding a new name to the master list requires me to recreate a link in every table which defeats the purpose of it trying to save me time having to modify something different on every table. Also each of these lists are sorted or filtered often which I want to avoid being reflected across all of the other tables and lists.

Hello all, I was wondering if anyone would be able to help with a macro or even formula that would remove the entries in Col A that appear in Col C. Attached is an example with dummy data, Col D is how the list should be. If a number appears in A but not C then all instances of it should be kept, conversely if it is in C but not A then it does not need to be kept. Most importantly I need to be able to delete those that appear in both by the same number of times they appear in C.
Hope this all makes sense. Please feel free to ask if it is not clear.

I have a worksheet as shown in sheet 1
With I click on the Macro Button I want to display the contents as shown in sheet 2
That means
In sheet 1 there are number of items purchased shown with different rates.
After clicking on the Macro button in Sheet2 I want the following
1. All the single entries purchase should not be displayed
2. All the items purchased 2 or more times but same amount should not be displayed.
3. Only items purchased two or more times should be displayed and that also with different values. Here if the item is purchased 4 times but only once the amount is different then also it should be displayed.
I have given only few items but actual items are more.
The serial numbers should also be arranged automatically starting from 1,2,3, etc.
What is the code if I do not want to change the serial numbers. with a suitable macro.

I have a spreadsheet of over 4000 rows. Column 1 is the part, column 2 is the order #, column 3 is the line # from the purchase order, column 4 is cost. I.E. Part- M12053235, Order #- 580001, Line #- 2, Cost- $563.00
Our software duplicated some of the entries and I need to find a way to remove the redundant entries.
I tried using this formula =if(and(b1=b1:b3909,c1=c1:c3909),"redundant","no")
That formula doesn't work because if it does have matching values in column 2(order #) then it looks to see if column 3(line #) matches anywhere in the spreadsheet. Since the data in this column ranges from 1-30, there is always multiple matches. So, my formula shows a redundant entry even when it is not.
I need to find a way so to check if column 3 has matching values in column 3, but only for the range of cells that corresponds to the purchase order in column 2.

After copying certain data into an excel worksheet, all entries in a column begin at 2nd space of each cell which I don't want.
I can manually backspace each entry to the first space of each cell. But I cannot backspace all entries at once even if I try Find then put in a space for find and then in replace leave blank.

I need to consolidate these two lists of data into one list.
First set is just a basic list of individuals with their data.
Second set is multiple entries for those same individuals. Each entry shows a subscription to a programme. The final single sheet should have one row per individual which shows all of the programmes they are subscribed to.
See attached, example sheet.
The real list is 3000 IDs, so need some kind of formula to do this.

I have two lists of product data, one for buyers and one for sellers (these are listed as A, B, C). The product names are not exactly the same (Eg Playstation and playstation three should be matched), I would have thought using the FuzzyLogic add in to match these would be the way forward! I need to rank the sellers by how many of their items appear on the buyers list

I have a list of email aliases for my company, approx 10,000 entries, mapping the alias to an email address. Two columns, one the alias firstname.surname, second column being the full email address. I have a second list, a subset of these aliases, approx 1200 of them, that are users of a particular web app. All i have in this list though, is the firstname.surname bit.
What I need to do is compare the lists, and where the aliases match I need to pull out the corresponding full email address from the long list, so I have 1200 aliases in the shorter list, with the full email address mapped to it. Is this possible in excel? i've tried all sorts of LOOKUP functions, and MATCH functions, but none seem to work. MATCH will give me the corresponding row number in the long list, but then it seems to offset itself every row it goes down, so the values are 1 out for every row. First row is good, second row -1, third row -3, fourth row -4 etc.
I don't want to have to manually go through 1200 entries and match them against a 10,000-entry list. Hopefully there's a quick way in excel to filter the long list down to the entries specified in the short list?

It's a quarterly schedule for utility meter readers, divided up into days across the top, and routes/areas down the side.
There's a space with each route for the employee ID to go, depending on who's doing it.
Down the bottom of the sheet, there's a few empty lines for all the available employees who haven't been allocated to a route.
On the second sheet labelled EMP LIST, is all the employee IDs. It's also got the areas they work- it's for something I want to implement later.
I can put all the employees into a single column list, then use basic DV to give a dropdown menu by each route, to assign an employee to it. This is pretty straight forward. I've also been playing with this in combination with a countif, so that employees already assigned do not appear in the list.
This is about as far as I've managed to get with it.
I need to get the employees who aren't assigned to anything to appear in a list below the routes. I'm fairly sure this is just another countif, but I'm not 100% on the exact formulas.
I also need the list in the dropdown menu to reset for each day of the quarter, i.e. if I assign an employee to a route on the 30th day of the quarter, their ID will disappear from the list for any other route for that day, but will still be there for the other days of the quarter.
So far the only way I've managed to do this is by duplicating the employee list for every day of the quarter, which is going to get very cluttered, and also makes staffing changes difficult. I'm hoping there's an easier way to do this using one data set.
I've added an example of the sheet. It's one week and it's only got about 1/3 of the routes we would actually have on any given day.

I have two lists in the same workbook:
List 1) Contains customer contact information, including an account number. These account numbers may be duplicated in the list.
List 2) Contains account numbers of customers who wish to be removed from the first list.
I need to remove the rows from the customers list (List 2) where the account numbers match, and also copy those to another list for review. So far, I can manually choose and run some code to remove one particular account number only (eg 123):
Set FoundCell = Range("A:A"). Find(What:="123")
'Locate information to remove
Do Until FoundCell Is Nothing
FoundCell.EntireRow.Copy
Sheets(" Deleted List").Select
'ActiveSheet.Next.Select
Range("A1").Select
Selection.End(xlDown).Select
Selection.End(xlDown).Select
Selection.End(xlUp).Select
ActiveCell.Offset(1, 0).Select..................

I want to remove all workstation numbers and their information which are not present on the first list from the second list.
In the first w.orksheet each workstation number is in a seperate row, and in column one (seperate cells).
In the second worksheet, each workstation number and its corresponding information is on the same row, and each different workstation is on a seperate row with its information.

I have a sheet (attached, Excel 2003) that I need an assist on. What I want to do is search the 'All Games' worksheet for the ten latest games a specific player has played.
That by its self might not be so hard, but I want to take those 10 rows (once identified) and take the sum of column G and divide by the sum of column F for those rows only.
I already have a concatenate cell in the 'All Games' sheet for each row that I use to as a link of sorts to get data from column F and G onto the 'Spring 2009' sheet. The way I have the concatenate set up, I can manually sort by it and get the 'latest 10' values I need, but I need to get it all into a formula to place on the 'Spring 2009' sheet without the manual sort.

I have a list of new payments received (sheet 2) along with their agreement numbers which I want to match to the list I had last month (sheet 1) to see which agreements are still paying, which have stopped and if there are any new ones.
The problem is that the the list of new payments received shows the agreement numbers with random prefixes and suffixes so my lookup returns #N/A
Sheet 1 - 24020130
Sheet 2 = 24020130FLE
My basic thinking (and I mean basic) is to do an edit/replace on sheet 2 entries and replace the FLE's with with nothing thus removing them completely then running the lookup but that doesn't tell me which are new payments received.
Then I could make sheet 1 text blue, sheet 2 text red, combine them, re-sort and manually go through the list but I'm hoping there's a sexy formula just waiting to be unleashed.
