I have a column where i have to put document numbers, Column A, i want to avoid accidently capturing something twice, so the only thing thats unique is the document number. Can i get an error if i try to enter the same number twice?

I have a userform that has a control button that opens another userform that contains a listbox with a range of data. I want to click on an item and press a control button to add it to a textbox on my first userform. I do this via:

I managed to find this great bit of code some time ago and would now like to add to it. The code basically identifies any duplicates in column A and then lists the results in a message box,e.g.:

Duplicate Name: REF12345 Rows: 2,3

Works great for 1 or 2 duplicates but if there are many it becomes quite difficult to keep track. I'd like keep the code as is but add highlighting to the identified cells.

I have three cells in a column. A1, A2 and A3. There are only 4 possible numbers that these can have in them, 0,1,2,and 3. Here is the catch. None of them can repeat, although they can be in any order. And the column may only have data in the first cell or the first two or all three. Is there a simple macro that will alert me to when a number is repeated? It needs to be a macro rather than a apreadsheet function.

I have a list of buses numbered something like this 320-360, 700-750, 800-899, 900-990. (but not always consecutive ie... 325 may be deleted). each day I want to enter them into a worksheet call "Shed" ( cells B3:E46) which is how they are parked ie.. bus 320 in B3, 321, in B4, .... bus 700 in E3, 701 in E5 etc....

I only want to be able to enter the bus number once so it won't be allocated in the shed more than once. (the code below provides this, but it also allows entries between the lowest and highest numbers which is not suitable.) The numbers are listed in column M to R

The numbers will also change after time, numbers will be added to and numbers will be removed. I hope I haven't waffled on too much. but that is basicly what I was wanting to do.

I have to type a an ID in column D of a worksheet called “restricted funds”, I have 13 sheets in that workbook and each sheet has in column D some IDs, I can not type a duplicate ID, in the that sheet. What is the best way to avoid no duplications. IDs are simply numbers.

With exception to Duplicate numbers on a single row, or column. I am hoping I can check an entire row against other rows, to see idf the same number are repeated.

Unlike the Lotto, this is about Safety boxes, where I have sequential numbering such as the following:

I have data and i would like to number duplicates next to the data so that i can append the cells that are duplicates easily. The data i have is in the following cell format -

Red Red Red Green Green Green Green Blue Yellow Yellow

What i would like is to output serial next to the cells based on the cell uniqueness as in -

Red 1 Red 2 Red 3 Green 1 Green 2 Green 3 Green 4 Blue 1 Yellow 1 Yellow 2

I realise there are a few threads on similar topics but I can't seem to get any of them to work for my scenario. I have two columns with a list of numbers in each. I'm after a function that will scan column A and identify any numbers that also appear in column B. If possible I would like it to then generate a list of these in say, column C.

I got some functions from some of you to spot duplicate bar codes

the first function was this =IF(ISERROR(MATCH(D5;$D6:D$65536;0));"";D5) the second next to it this =COUNTIF($D:$D;$D5) and the third: =IF(COUNTIF(D:D;D5)>1;"DUPLICATE";"")

well fine but now I dlike to add the numbers of the 2 cells of those duplicate codes. In some cases I have more than 2 identical bar codes.

I have in my sheet from C13 to C350 many serial numbers which I manually type them in. These serials are 5 digit numbers, and I was just wondering if there's a function or formula that will not allow duplicate numbers in that column.

I have 2 columns I need to compare, in column A a list of ref numbers aprrox 62000 rows, with some duplicates. In column C a list of ref numbers 38000 rows again with some duplicates.

I need to be able to compare Column C to Column A. I need to identify the first instance of a ref number that matches from C to A so that I can delete it. The second instance of this ref number I would like keep. I have tried the following with no luck.

I need to remove duplicate Part Numbers where other information in the cells will not match. In the following two examples, the only difference is that the COMP_ID: number is different, but for my purposes, the second example is a duplicate and needs to be removed. I have hundreds of rows of this type of information with various part numbers: ...

I have unit measures that are converted across four columns (FT, SQFT, SQM and SQY).

THere are three units in rows (BOX, Skid and Roll). I am trying to identify in a column labeled "Duplicate Volume" with a formula stating "YES" if there are duplicate numbers (volumes) in any of the four conversion columns listed above. I tried to attach an excel file here but the system will not accept it. Hopefully the diagram i make below will be enough to understand the concept:

Attempting to do a spreadsheet for my golf club, to record scores, etc...

Managed to get it to pretty much what I want despite some very extreme looking formulae! So for some scores such as 56,56,57,57,54,54, Rank would just give me 3,3,5,5,1,1, so I have put a second column next to 56,56,57,57,54,54 where I input scores to seperate ties (better back nine scores), so in the above I would have for example 30,29 next to the two 56s, 27,29 next to the two 57s, and 27,28 next to the two 54s, so the rank would return 4,3,5,6,1,2. I have gone three stages further, so if, the back nine score was also tied, I have a column for the last 6 hole score, the last 3 hole score and even the last hole score. This is some serious formulae at this point. However, I now want the OPTION to rank the original data as 2,2,3,3,1,1 if I don't put any data in the back nine column.

This is so that I can input doubles scores on the same spreadsheet as singles scores, so if two people shoot the same score in singles I can input the back 9 scores etc to decide who comes out ahead, but in doubles I would just leave the back nine score blank, and then two people would share 1st in the rank, but then I need two 2nd ranks NOT 3rd ranks as it currently is.

Just so you can see how complex it is the current forumlae in the rank is here is an example:

My boss gave me a project and need to be done as soon as possible. Basically, i just need to join all of database and then identify duplicates and put them in another sheet in order to investigate if there are any double payments.

Duplicates can be:

- invoices with same vendor name having same or comparable amounts - invoices with Invoice No. which match or closely match (in case we're mis-keying)

I've tried so many ways to find duplicates that fulfill the 2 conditions above, but still cannot make it done.

I must determine out of 52 radom numbers the average of the 48 highest even if one or more of the lowest numbers is repeated 7 times without exempting the 3 out of the 7 that must be included in the 48 to extract the average.

I am trying to find duplicate numbers in sets but so far I can only highlight the ones that are in exact order. I need to find each set that has the same numbers, in any order. Example..

I will provide an example of sets of 3. But I get 3, 4 usually but sometimes 5 or 6.

I get them from different people.

Person A- 234, 569, 498, 849, 848,343,567,347 etc...

Person B- 432, 596, 677, 566, 565,433, 455 etc..

Now I need to find each set that has the same numbers, any order. Like 234 from A and 432 from B would be the same, so I would need to highlight them 2 sets. But I can not figure out how to do this. For Excel to highlight it they have to be 234 and 234. Does not recognize same numbers, different order.

my spreadsheet has duplicate serial numbers in column A and the corresponding row in column B has mutliple descriptions for the same serial number. I need to combine those descriptions into 1 cell rather than having multiple rows for the same serial number. is there an IF formula that I can combine with a concatenate that will capture what I need?

I have a table that is 94 columns *12 rows each cell has a different number I need to find a way to duplicate the table but with the numbers in each of the cells doubled.

I have a sheet where i want to delete duplicate rows where column A and column B combined are equal, i.e. range(Ax:Bx) where x is the current row. I am using the macro below but cant seem to get it working as I keep getting a type mismatch error and Im not sure why.

I have a mass of data which look something like this:

table removed

and I require the ranges of reference numbers to be listed in a column one above the other, which requires inserting new rows. I also need the date & description columns copied down into the newly inserted rows.

So basically for example I would want the top row to now read:

table removed

and then apply the same procedure to the other ranges below this.
