How To Prevent Duplicate Records From Being Entered On Recording Sheet
Feb 9, 2013
I have a created recording sheet (attached) for the purpose of recording moths. I send this sheet out to those recorders who live in my county and at the end of the year they send the filled in sheet back to me. Over time I have put safeguards onto the sheet to ensure that I get the cleanest data returned to me. However, there is still one area which is giving me problems - users entering duplicate records.
Some formula which will stop recorders from entering those duplicate records. There are many columns on the sheet which recorders have to fill in with information, but as far as the duplicate records are concerned it is where the same information is entered into columns C, F and J that I'm having a problem with. It would be great if, when the same information was entered in these columns that the affected cells were highlighted in some way and if an error message appeared saying 'Duplicate record, either delete or alter grid reference'
I have entered two test duplicate record on the 'macro moths' sheet of the attached file : Test Recording sheet.xls

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 am using the following code to remove duplicate records from a sheet:
[Code] ....
It successfully removes the duplicates (based on Columns A and B), however it is changing the formatting of the cells and messing with the conditional formatting I have on the sheet.

I have a range of columns i.e. 23 columns (i.e. B through X). Someone can write records in these columns (starting from B21).
Duplicates are considered the rows with similar data in columns 3 and 11. I know about the removeduplicate method and works really well but i want the duplicates not to be removed. Instead another column shall be checked for date of entry (user will entry date in format dd/mm/yyyy). The newest entry will change the value of the cell in column 4 (islatest column)to TRUE while all other records will be FALSE. This will work with the filtering of data on a pivot table on another worksheet.

I am trying to collect data from a server. The data comes through as .csv (seperated data), and I am able to get all the useless info/columns out of the way - but I would like to keep a record of how many times these "alarms" come in. form a spreadsheet, or tell me how to go abouts using a tool to simplify my process.

example of a database user form that will allow me to list records in a sheet as well as search for records in a sheet. I know excel has a built in feature for this but it is menu driven and I need something that is button driven and will allow me to resize the form layout. I was not able to figure out how to do that with the built in form.

Is there any neat little way of preventing a character say '=' from been entered in a cell, kinda similar to the validation but for a 'dont allow' function.

What formula can I use to accomplish the following, if it can be done.
If B9 is 100% all the rest of the % cell inputs would be 0%
If B9 is less 100% ,lets say 50% all the rest of the % cell inputs would be less than or equal to 50% until any sum of those cells equal to 100%
in which case if I enter 50% on B9 and 25% on D9 and 25% on F9 their total sum would be 100%.
If I try to enter a % on H9 it should not allow me to do it
because then the total sum on O9 would be more the the original amount on A9

I currently have a monitoring spreadsheet which my staff enter data into each month. There have been some problems with staff entering data wrong so I have decided to build a userform to prevent errors. I have 2 combo boxes one for selecting a month of the year and another for a particular call the user must enter data for. I want the userform to enter the data from the userform into specific cells in a specific area. e.g. If a member of staff entered data into the userform for February, Call 2 then it would appear in the relevant boxes.

Should be simple but I can't get this to work,
I have used =value(a1) that prevents any formula, but it also prevents a zero being entered.
I have amended trying and/or statements in the validation but then it allows zeros and formulas!

I have 2 columns A and B.
There are 1000 records in column A and 500 records in column B.
I would like to compare both columns for duplicate entries and deleting all instances of those record in both columns, leaving behind records that were not duplicated to begin with in their respective columns.

I have a single-column list. The column header is 'ID'... records within this column repeat sometimes (this is ok). I need a worksheet function that will allow me to mark the second, third, or fourth duplicate, but leave the first duplicate alone or unmarked. I have searched the Web and this forum, and came up empty. If this cannot be done with a worksheet function, then VBA is welcome. No ColorIndex.

In Column A, is gender: male/female
In Column B, is name: Bob, Jon, Mary, etc
In Column C, is salary: $40, $30, $20, etc.
In column B, there will be instances where a name might appear more than once. I want to be able to do a sumif formula of Column A and Column C, but not include any records where a name in column B is listed more than once. Is there a way to do this?
1 Male Bob $50
2 Female Jane $30
3 Female Kate $20
4 Male Mike $30
5 Male Bob $50
So if I wanted to sum all male salaries above, it would be $80, not $130.

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.

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 spent the last couple hours compiling a large amount of data. I have a list of websites, each have a number of visits and transactions. The list is many thousands strong so i have a huge amount of data to work with but there are a lot of duplicate sites. See below, I have taken a snapshot of some of it:
I've highlighted a duplicate example.
Would it be possible across the entire data set to sum all of the duplicate rows into one. So, for the 3 shown, to be reduced to one row with 228 visits and 2 transactions?
And to do it quickly? As I could go through them manually but I don't have to time to go through 10,000 rows.

Wondering if there is a way, script-wise or formula-wise that will look through a table and find duplicates but not just any duplicates, it has to match a certain criteria.
For example, I have a column for UPC and Vendor#. I have my table sorted by vendor (all 159 of them in one table) I want to find out whether a UPC appears more than once for a vendor.
UPC --- Vendor
11254 135
11251 135
11251 135
11254 9345
11251 9345
Here, as you can see, UPC 11251 appeared more than once for vendor 135. Can this be done through conditional formatting ? or a script?

In my sheet I have it search for duplicate records and give those records the same id. Is there anyway to combine data into one record. For example, I have a person with a value in column Points1, on another row a value in column Points2, and another row a value in column Points3. I want take those values from the duplicate records and put them all in one record. I've attached a sample.

I have one main tab which I pull data from other various tabs. To match data the data, I create a "common unique ID", in other words I create a column on each tab and connect various cells with the ampersand.
So in each of the various tabs (and the main tab), I'll have a column with something like =A2&B2&C3
If the "unique ID" matches between the tabs it will pull back the desired phrase, or it will be left blank. (Just using an =IF(ISNA) formula)
If you have followed so far, on my main tab, I have a column for each of the various tabs. The information I am trying to match could be on any of the tabs, so I need a column using an =IF(ISNA) formula to attempt to match each tab. So, on the main tab, there are several columns which might have the phrase I am looking for. I use another ampersand function to add those columns. My problem is that occaisionally, what I am looking for is on multiple tabs. So, if I am normally pulling the phrase "Pending Loans Report" when a match is made, if it is on two tabs, the cell will add it twice "Pending Loans ReportPending Loans Report"
I realize this is confusing, so I attached a spreadsheet. The "main" tab I was referring to is sheet1. I really simplified it down to post here, but I think the main idea of my problem is still evident. The problem is line 15. Note how column M has "Pending Loans ReportPending Loans Report" - I'd like it to only say this phrase once. The macro pastes special values at the end, but I've highlighted some cells in red which show the formulas I used for that column. Columns N, O, P, Q, etc. all have virtually the same formula.

I've got this code for prevent duplicate entries, But I wondering if it's possible to add a copy rows to it? For Example
Columns C
ItemID ItemName
11 QWE
22 ASD
33 ZXC
So now I enter 22 in ItemID for this working code it will pop up a MsgBox saying Aready exist, Is it possible to add a code so that it will copy the existing copy and paste into the active row?
Private Sub Worksheet_Change(ByVal Target As Range)
Dim r As Range
Dim ans As String
Const myCol As Long = 3
If Intersect(Target, Columns(myCol)) Is Nothing Then Exit Sub
Application.EnableEvents = False.........
