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

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.

I am having a sheet where I keep track of when online surveys have been sent to users. The users enail address (column K) may be on the list for several times, but I need to make sure that there is at least a 7 days pause between sending the first mail and the second, depending on the visit date (column G).If there are less than 7 days between two entries with the same email address, the user is not qualified for taking another survey.
I was thinking to write an IF formula which returns either 1 or 0 and then let conditional formatting highlight and HIDE the row via a VBA loop.

Is there a formula that will allow me to look for the existence of any number value in a row of one worksheet and then return a specific number value in a cell on another worksheet? For example, if the formula finds any number value it will always return the number 15 to a cell on another worksheet.

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] .....

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.

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.

I have a huge database consisting of zipped file names which i created by importing the directory listing into excel. The zipped files contain two files each an mp3 and a correspondent cdg file (karaoke files).
I continue to add new disks (as I acquire them) to my collection. the trouble is that new disks have some songs already in my collection and I do not want to waste space in hard drive with duplicates. The existing data is arranged in a worksheet by columns as follows:
Discnumber | track number| artist | song name | path | complete file name
what I would like to do is to check the ** listing after import it to excel in the same format (i can do this part ) and then check it against the 10,000 plus entries that i have if the artist-song name combination already exists in the data. If so return the row in a separate worksheet or pivot table so that i can check it. this way I would only save the songs I do not have in my hard drive thus avoiding duplicates and saving precious space.

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.

If I enter into a textbox1 the following 09/31/2009 the result is that its not a date (because there is only 30 days in September - not 31). OR if I put in "13/25/2009"
Can I have a macro that checks whether or not its a valid date and if so a message box appears that says:
"Invalid date"

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.

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.

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.

I have a worksheet in which i am asking a user to enter manually a number in cell E3. Suppose the user starts with 100, then the next time he is entering in E3 he shoudnt be able to enter 100 nor any number less than 100. I dont have a range for the numbers that the user is going to enter.Therefore countif function does not work. Is there any way that i an store the number taht the user enters first in cell E3 and then use that database to avoid the user from entering the same or a number lesser than that number.????

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
column F - should only contain 2 comma's(or 3 keywords)
all columns - check if no entries are found(empty cells)

I have a workbook with a list of new contacts in one sheet, and a list of old contacts on another sheet.
I want to run a duplicate check throughout the workbook to highlight and delete any contacts on my new list, that have already been contacted on my old list.
Also, I need the the duplicate checker to check for non specific names, regardless of punctuation, upper/lower case, etc.
I need to to highlight all of the following variations as possible duplicates which i can then review & delete manually;
Apple Corp,
Apple Ltd
APPLE LTD
Apple.com
etc...
What I can use to do this?

I have an order form created in excel with a list of about 1600 products. I have a column set up for the customer to place the ordered amount of each product. What I need now is a way to transfer only the rows that have a value in the "ordered" column to a new sheet. I have seen it before , but don't know how it was accomplished.

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.

I have a spreadsheet that will export records when I "click" a button, to a spreadsheet on a network drive.
I would like to attach some code that will check to see if a duplicate record is going to be written to the network drive, and if so, alert the user that they are about to create a duplicate . If it is a duplicate, give the user the option to overwrite the existing record.
Ex. I export the results for account 12345.....Account 12345 is now written to an outside sheet.
User2 logs in and works with customer 12345, w/out knowing that someone has already worked with this account, presses the export button.....This is the trigger point for what I want to happen. At this point when it locates a dupe in the outside spreadsheet it will prompt the user too make some chouces .
find attached the code I would like to attach this to...

I have written some code which asks the using for a name, selcet's a sheet, copy's the sheet, rename's the copied sheet then hide's the original sheet and makes the copied sheet with new name active.
My problem is that I need some sort of code to check for sheets with duplicate names and if true ask the user to rename the sheet or maybe delete the sheet.

I've been assigned to develop a workbook that autopopulates a different workbook but they wanted it so the second macro is never messed with and the information is only entered once. Here is the macro i developed
Code:
Sub Monthly()
Dim wbthis As Workbook
Dim wsthis As Worksheet, wsm As Worksheet
[Code]....
Now The area in red is where the macro writes into the form. My thing is that I want to set up a check so there isn't duplicated entries. This is how the check would work. First it would match up any excisiting entries with JobNo and then check to see if the JobDate was the same. If both are the same then it would check Waste or CutTime, either one would work. If they didn't match, then those cells would be overwritten. If nothing matched then it would put in the new entry.
