How To Prevent Duplicate Entry In Column

May 25, 2009

I have a huge worksheet with 26 columns and 1200 rows. This worksheet is updated by 4 people everyday. Column C, H, N & R are updated daily by these 4 people so these are dynamic columns so to speak. I would like to have a VBA that informs that particular individual when he enters a duplicate data, maybe a popup saying duplicate entry.

Macro To Delete An Entire Row If A Duplicate Entry Appears Only In A Certain Column.

Feb 20, 2009

Is there a macro to delete an entire row if a duplicate entry appears only in a certain column.

1. Look for the column header with the name "File Number"
2. Anytime the same number under the "File Number" column appears more than once in that column, keep the row that contains first occurrence of that number buy delete the entire row anytime that number is repeated in another row in that same column.

This is regardless of what is contained in the other columns. For example..let's say these cells contained this data...

B1 - UTE00225
B2 - UTE00546
B3 - UTE65513
B4 - UTE00225
B5 - UTE00225

In this case, I would want to keep rows 1, 2, and 3. But, I would want to delete rows 4 & 5 because the number "UTE00225" has already appeared first in B1. I'm using Excel 2003.

User Box Options If Cell Entry Is A Duplicate Found In A Table Column

Aug 23, 2009

I have a table that i use for a customer database. and the end user adds new customers to this table, what i would like is for a message box to pop up whenever cell B2 matches an entry in a column in the customers table. the table starts on row 25, and the column i would like to check for duplicates is column B. I would like the message box to give the user the message "A customer by this name already exists, Would you like to load this customers file?" If the answer is yes, then the row that the match was found on would be copied and pasted onto row 1. if the answer is no, then nothing else happens. I hope this makes sense, i am posting this sheet of my workbook for reference.

Testing For Duplicate Entry

Oct 18, 2013

I have a form that information is entered in. At the end the user can then save the information in a spreadsheet by pressing a command button. The updating to the spreadsheet works, it is the part where the last entry is tested against the info on the form to prevent a duplicate entry that do not work.

I have tested that the program reads the info from the spreadsheet (see the commented lines).

I can attach the whole spreadsheet, but some of the entries on the form are linked to another spreadsheet that make it a bit cumbersome to attach two files.

VB:
Private Sub cmdUpdate_Click()
Dim lRow As Long
Dim ws As Worksheet
Set ws = Worksheets("TonnageInput")

[Code] .....

Restrict Duplicate Value Entry In Textboxes

Nov 24, 2008

I have a userform with 8 text boxes and users have to enter different numbers separated by commas like 1,5,6,15,28 and so on.

I want to put a validation that if a number is entered in any of the textboxes than the same shall not be allowed in any other textboxes. Even in the same text box, no duplicate number shall be allowed. ie if in a textbox 1,2,15 is entered , then in the same textbox also, user cannot enter 1 or 2 or 15 again.

Prevent Duplicate Entry From Textbox Into Different Worksheet

Jun 12, 2009

I have a entry form in which i want to register customers. the first field is the customer number (which is unique(created by me) for every customer). This is TextBox 1 in the document. I would like to search for duplicates in worksheet 2, collumn A, when pressing "enter" to move from TextBox 1 to TextBox 2. A search for duplicates should start and a message should appear " duplicate found" if found, otherwise continue to TextBox 2 for further entry of information.

Please see my attached document for clarification.

Automatically Check Each Worksheet For Duplicate Entry

Apr 17, 2008

I have multiple worksheets of computer equipment, each worksheet is a group/department. Column H is the serial number column and the entries have to be unique. I have managed to create the code below which does find duplicates across worksheets.

When error message pops up about which sheet the duplicate already exists on, the duplicate entry is deleted and the cell is blank but the error checks again and reports the blank existing on another worksheet and then it is stuck in a loop. How can I ignore the blank or null.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim I As Integer
I = Sheets.Count
If Not Intersect(Target, Range("H2:H200")) Is Nothing Then
Do Until I = 0
If Application.IsError(Application.Match(Target, Sheets(I).Range("H2:H200"), 0)) Then
Else
MsgBox "That entry already exists in the " + Sheets(I).Name + " sheet"
Target.ClearContents
End If
I = I - 1
Loop
End If
End Sub

Macro For Data Entry That Checks For Duplicate Record

Dec 31, 2013

I have a spreadsheet that uses a Form for Data entry. Each record has ID, Name, State, and about 20 more columns of information for each ID.

The data entry is working well.

What I need now is to add a check for a UNIQUE ID. If they are adding a new record I need my form to return a message if the ID they use is already in the database. So if they enter XXXXX and that is in the file already - they should get a message that XXXXX is already in the database and to please enter a new ID.

And once they fix XXXXX to XXXXY then the record is added.

I should add that the ID is stored in column A.

Data Entry By Textboxes On Userform - How To Prevent Duplicate Record Being Entered

Jan 3, 2013

I have created a userform with 3 text boxes. It also has three buttons - clear, Cancel and Generate record button.

User form takes entries in the three text boxes and on clicking the Generate Record button, the values of the three Text Boxes are inserted in Column A, B and C of sheet1. The columns keep on populating with new data on each submit in the row below the last record.

Now it is required to enter data only if the value entered in TextBox1 is new and has not been entered previously in column A. If textbox entry is already aviailable in column A, a message box of 'Record available' shoud be prompted and the text entry must not be allowed until the data entered in TextBox1 is not unique.

making a macro that will scan for duplicates, length & empty cells.

I have the sample file below that does conditional formatting but it doesnt help as much because I want to show the reason for the highlight's on a comment instead.

sample file : [url]

file that might help out: [url]

checks would be:
column A - duplicates and/or length should not be over 100 characters
column B - duplicates

Remove Duplicate Addresses

Jul 6, 2009

I have 2 issues i am trying to work through, i have a spreadsheet with 3 data sheet tabs, the first issue i have is in Data sheet 1 I have a lot of duplicate addresses, I was wondering if there is a way to filter out the duplicate addresses so that only one of each address is showing.

Issue 2 that i have is a lot more complicated, In data sheet 1 i have a list of medical providers that reimburst at 110% or more, each address on that list needs to get 1 letter mailed to them, but i have to keep track of how many are going to each region, i.e. Columbus, OH region, Cincinnati, OH Region, Toledo, OH Region, and Cleveland, OH region. So what i want to do is create a 3rd data sheet that keeps track of total letters sent by region, but was wondering if it was possible for this info to be automatically transfered from data sheet 1 to data sheet 3. I don't need all the information in data sheet 1 to tranfer to data sheet 3. All i need is for data sheet 3 to read off the City field in data sheet 1, and calculate 1 letter sent to that region.

I dont even know if this is possible, but it is way beyond my realm of excel knowledge which isn't much.

Any help would be appreciated. I am trying to attach the spreadsheet, however it isn't allowing me to attach it, i keep getting a database error, when i upload it. It is under the max size limit too. Not sure what's going on.

Remove Duplicate In List

Sep 4, 2013

I used to have a macro that did this for me, but the layout of the exported data has changed and now the whole macro has had to be rebuilt.

I've got a list of two pieces of data: Material (Column A) and Order (Column B). I'm putting a spreadsheet together and populating it with VLookUps. This spreadsheet will list the materials and the Orders after each, but then I also want to list the second Order in the next cell if there is a second order.

For instance, in the below, Material 10880873 has two different Orders. The first VLookUp grabs Order 513792568. I need the second VLookUp to grab the next Order 513792569.

MaterialOrder
12012223513571068
12149080513739571
10880873513792568
10880873513792569
12215347513792570

How Do I Remove Duplicate Cells

Jan 25, 2010

I have two columns each of 5000 cells. Some cells of column A are duplicated in column B. The duplicates are not necessarily on the same rows. How do I delete the duplicates?

I've spent hours researching for an answer and I've tried Data>Filter>Advanced Filter many many times and it does not work. The two columns just sit there. Shouldn't this be a very easy thing to do in Excel?

Prevent Duplicate Data Entry Via Userform Based On Exact Match In 2 Columns

Jul 16, 2012

I have a userform with several textboxes and 2 comboboxes. The data that I need protected from duplication is based in the comboboxes. If I ignore the other fields and presume the following it may be easier to understand:

The comboboxes are populated by the data stored in sheet1 and when the userform is complete, the OK button populates all the data into sheet2

Combobox1 contains names eg, John, Julie, Bob etc
Combobox2 contains colours eg, Red, Blue, Green etc

I want the userform to allow the data to be entered into sheet2 only if it is not an exact duplicate of the choices in BOTH of the comboboxes

For Example
John Red
Julie Red
Bob Blue
John Blue

These are all ok, however, to try and enter John Red again would bring up a message box indicating a duplicate entry and prevent the data from being entered.

How To Remove Duplicate Values Of Last Name List

Apr 24, 2014

So for a project I need to put together a list of Portuguese-speaking last names. So I have various sources where I copied from, so I have one column in excel where I put all that data. I sorted the data to be in the correct alphabetical order. But when I try to remove the duplicate values in that column is says it removed them but it didn't and when it does it leaves many behind. I have tried the trim function, and even formatting but nothing works. I attached the non-formatted and non-trimmed list, because it doesn't seem to be making a difference.

Macro To Remove Duplicate Data?

Aug 17, 2014

I am trying to create a summary sheet that updates when input data is added.

I'm still learning many parts of excel and I'm unsure why the SUMIF function on occasion leaves duplicate data in.

I can live with the fact that I will need to correct the input data and am willing to just paste in corrected data when it has been validated via the data validation tab.

Once this has been done, all I am seeking is for a subsequent process to start which updates a summary sheet with the sums correctly adding via the sumif function.

I have left some instructions on the actual spreadsheet to clarify my intended results.

Keep Only Duplicate Records And Remove The Rest

Dec 12, 2012

My spreadsheet has more than 200 columns and 5000 rows of data and blanks. When I select all columns and rows and remove the duplicates, 6 records are removed. I need to only keep and be able to identify those 6 records. I could use something like =IF(COUNTIF($A$2:A2,A2)=1,1,0) if I had only few columns that would identify dups but since there are so many columns it would be prodigious job to create one formula for each column and filter through 200.

Remove Duplicate Values From Listbox?

May 14, 2014

Column A has values increasing by 1 but not necessarily each row, i.e.

1 1 1 2 2 2 3 3 3 4 4 4 4 5 5 5 5 7 7 7 8 8 9 10 10 11 11 11 11 12 13 13 14 14 14

I have a listbox which I want to Initialize by listing these values but not duplicating them (so in this case it would contain 1-14). Here is the mindblowingly complicated code I currently have:

[Code].....

This gives me the list as it appears on the sheet but doesn't get rid of the duplicates for me.
