I am looking for either vba or excel method to prevent duplicate entries across multiple columns. The data validation only works when it is input manually by the user and not when it is generated by the formula
What i am trying to do ( assuming " | " are column dividers and each new line is a row)
abc | 2 | bac | 3 | cab | 4
bac | 3 | abc | 2 | cab | 4
abc | 2 | bac | 3 | cab | 4
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.
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.
A
B
Song
BandName
19
Paul Hardcastle

how i can set 'Data Validation' to stop me from entering duplicate values across multiple columns, i can set it for a single column i.e. A1 to A100 but i am after this but for something like A1 to H100.....?
I am currently using this formula in Data Validation:
=COUNTIF($A$1:$A$100,A1)=1
I need something to do this but for multiple columns.
I have a userform that I use for data entry with lots of combo boxes, list boxes and text boxes
One thing i haven't cracked yet is to check for duplicates against two matching fields
If a user (for example) enters 'SAB' (which will be stored in column A) and then 'UK' (which will be stored in column B) and there is already an exact match for both, then I need to inform the user that a matching record already exists
The following is OK: (the dots below are meant to illustrate spaces between the columns!!)
Col(A).....Col(B)
SAB........UK
SAB........USA
SAB........Italy
BUT, if a user then tries to enter:
Col(A).....Col(B)
SAB........UK
I need my userform to register a duplicate entry.
My sub routine is detailed below : .....
I have data (e.g. PPL0106AU) in columns A (Rows 2 to 104) & C (Rows 2 to 303) and need to identify which entries are in BOTH columns.
I've entered in column B: =IF(MATCH(A2,C$2:C$303),A2,"No")
This formula is resulting in a duplicate of column A in column B.
I have attached a before and after image of what I am looking to accomplish.
In the before image, you can see that there are 3 rows of data
- a header
- a repeating model number (in column F) with accompanying data (values in columns G - J are the items of interest)
In the after image, you can see that I took the 3 rows of data and turned it into simply two rows of data
- a header
- the repeating model number
What I did however in the after image, as can be seen, is I took the data that appeared on the repeating row (Row 3 from the Before image), and included the PRICE, COST, BEGIN, and END values in new columns on row 2.
The model number is the same of course, which is why I did it that way.
If the model numbers were different, I would have simply left it alone, as-is.
Is there a way to accomplish this via some functions or maybe even a VBA script?
By the way, if we have to dump all of this onto a new sheet, then so be it.
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?
=(COUNTIF('Cases Closed'!O:O,"John"))-(COUNTIFS('Cases Closed'!O:O, "John", 'Cases Closed'!X:X, "*Solution*"))

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.

A , 1 , 1

I need to eliminate duplicate entries WITHIN a row. So, I need the table to become:

Is there an easy way to do this for a large sample? Also, there are actually more like 8 columns of this data, if thats important.
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

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).........................
I want to use (VBA) data vaildation to restrict duplicate entries.
Worksheet Name = "Metal Type"
NoDupe Cell = B15 (allowing text and numbers)
Range to check = (Sheet)="Metal Type" (Range)=A21:A100
Error = Message box "Enter Unique Name in Cell B15"
Then Exit Sub
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.
View 2 Replies View RelatedI 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]

I have a userform created to enter clients information which by submitting goes to sheet1 ..
Now the challenge is i want to make sure that no duplicate entries are entered thru userform.
And if duplicate company name is entered then all the client details of the other fields of the userform shall display the values of previous entry so that i can edit the latest changes to the sheet.
I currently have a sheet of 20,000+ items and 2 columns. My first column is an part number and the second is a date. Each part number can be show multiple times but will have a different date each time. What I want to do is that the first occurrence of each part number (and corresponding date) and put it in sheet 1, the second occurrence of each part number and date into cell 2, third in cell 3 and so on... not all part numbers are showing multiple times, only certain ones.
