Count Duplicate Records

I want to be able to count the total number of unique records for my analysis.

However.... I cannot do this by simply highlighting the column and seeing what the cell count is because there are duplicates in my data.

column A has a list of id's eg below: There are 5 unique records not 10.

I want to be able to get this unique record count for my long list of data.


Is there a simple formula I can use for this???

Many thanks in advance.

I have looked over the forums for information on how to do this, and can not find anything. I have used conditional formatting to identify duplicates in my spreadsheet. I have a unique user ID, which combines the first and last name fields into one. However, in 10,000 there are a number of John Smiths, Joe Adams, etc. With smaller lists, we search manually, and then add a 1, 2, 3, etc to each duplicate to create a unique value for the User ID.

My question is:

Is there a way to check for duplicates, and then automatically add numbers to the duplicate values to make them unique? If so, how can this be done?

I think I have done a good job in illustrating what I would like to be able to do, but if there is still something that is unclear, I will post whatever clarification is needed.

I am trying to filter a list of records by the value in a cell and then (for the filtered result(s)) change the value in column Y just for the filtered results. This is the code I have at present which filters the records OK but I can't fathom what I need to do to ensure I only chnage the value of the cell(s) in column Y?

[CODE]ActiveSheet.Range("$A$1:$DC$5000").AutoFilter Field:=1, Criteria1:="GI255"
'After filtering I want to change the value in column Y for only the filtered entries CODE]

I just worked with a data set where I needed to create a unique key based on existing information where no unique key was set up as a field. I accomplished it by concatenating (using the & [concatenation] operator) several fields based on what I hypothesized and observed about their content.

I'm thinking there has to be a more automated way to discover the best unique key of existing fields and their data. I thought I'd post this as a challenge because I don't know the "right" (or better) answer.

Anyone have any ideas?

Hello, I'm trying to count the number of times a name appears across multiple worksheets but I can't seem to figure it out.

I have 6 sheets to count and all the names are in column A (from A1:A100) on each sheet. The names are not in a particular order.

On sheet 7 I want to have a cell beside each persons name that counts the number of times their name appeared on the other 6 sheets.

For example Sheet 7 (called total) would have

Joe 5 (where 5 is the outcome of the formula I'm looking for to count all the times "Joe" appears on sheets 1-6).

I have it counting per sheet with =COUNTIF(A1:A130,"name") but this is not quite what I am looking for.

Thanks in advance for any advice.

Edit: I am using Excel 2007 w/ windows XP

Hello Everybody,

I am hoping for some assistance. Here is what I have....

I am trying to get counts of certain values.

This is in the same workbook but different sheets.
On sheet 1 is where my formula lies. In a cell, I want it to look at sheet 2 column B and look for instances of "A", then I want it to look in the same row it found "A" and look at the value in column "N" and evaluate if there is an amount. If there isn't skip it and don't count it, if there is a value count it if it falls within a given range.

An example of the formula is below...what am I missing?


Thank you in advance for your assistance.

Sorry for the question. Normally I find answers to my excel questions by going through the help tab or by searching on Google. However, I don't even know what question to ask on this one!?!

Basically I have created a spreadsheet with several columns, but I have one column that lists the shirt size (YS, YM, YL, AS, AM, AL, XL, 2X, 3X) of each person. Is there a formula that I can create that will tabulate the number of sizes (i.e. AS=2, AM=7, etc.)?

In previous years I made a column for each size, and simply placed a "1" in the correct column, and had excel just add the 1's from each column. However, that takes more time and space. I was hoping to streamline it this time around.

Thanks for taking the time to read this post. Any help would be appreciated! Thanks, doug

I need the necessity do delete a sequence of sheets in my workbook.
If I use this code:

With ActiveWorkbook
If .Worksheets.Count >= 5 Then
For n = 5 To .Worksheets.Count
Next n
End If
End With

I receive a confirmation message box with this message:

"Data may exist in the sheet(s) selected for deletion. To permanently delete the data, press Delete" [DELETE] [CANCEL]

I wish to delete all sheets without receiving any message.

Is it possible?

Many thanks in advance for your kind support.




I would like a formula that would list all the items in row B that match the criteria in row A. the first cell with formula would list the first item, the second cell with the formula would list the next item, and so forth. Also, column B might have a duplicates that should be listed. Is this possible? I cannot manipulate the order of the original items (ie, filters) because this data is being used to derive other formulas.

This is probably an easy question for most of you, but it's killing me. I tried searching before I posted this, but the suggestions given didn't seem to work for me.

I need to look up data from a cell on one Excel sheet, compare it to a list on a 2nd sheet and when they equal, take a value from a different column on the 2nd sheet and drop it back on the 1st sheet. Since that's a horrible explanation, let me try explaining it this way:

Sheet 1
Column A has a long list of code type 1s
Column E has a long list of code type 2s

Sheet 2
Cell C2 has code 1
Cell E2 needs code 2

I know it should take an index/match function, but nothing I try is working. What I'm trying is the following formula in Cell E2 of sheet 2:

=INDEX('Sheet 1'!A:A,MATCH(C2,'Sheet 1"!E:E,0),5)

But all I get is no result. What's driving me bonkers is that if I copy everything over to a single sheet, that formula works fine.


I have a column with a set of duplicate values. I need to remove the duplicates while leaving the original data and keeping the blanks. The Remove Duplicates function comprises the data and this does not work for me. Help!

Hello all,

Until now I have been able to find all my answers through searches. As a VBA novice, it has been very helpful. I am stumped on this one, however. I am trying to autofill from the selected cell in Column C down. I would like it to stop at the last cell with data in Column B. This is the code I have so far:

Selection.AutoFill Destination:=Range(Selection, Selection.End(xlDown))

This does the autofill, but doesn't stop at the last cell with data in Column B.

In the past I have use this code to acheive similar results:

Dim endRow As Long
endRow = Cells(Rows.Count, "B").End(xlUp).Row
Range("C2").AutoFill Destination:=Range("C2:C" & endRow)

The problem with this code is that I will not always be starting in "C2". I need code that uses whatever the selected cell is.

All help is appreciated. Thanks!

Hello everyone, I am new to this forum and have been using excel for about 3 years. I have learned alot but still can not figure out how to make numbers add up in one box like a running total. Meaning, If I have a list and in the list is one cell for each item say like cell a1 is for a can of coke and cell a2 is for a car tire and so on,and i want to keep a running total by adding a number to cell a1 or a2 like say "3 i.e. 3 tires or cans of coke" and later that day i come back and need to add 2 more i want to be able to just click on the cell a1 or a2 and enter the number 2 and the cell would add the number in it to the number im adding to it to show a result of 5 tires or whatever. I am sorry If i am not asking the question in an understandable manor but its the best way I can think to ask anyways, any help would be appreciated, Thanks in advance.


Hi there,

I have a spreadsheet with some cells setup with a drop-down list containing
Y, N or N/A

This is being used on a TabletPC but if I make a mistake or need to change
back to a blank field I have to invoke the soft keyboard, activate the cell
and hit backspace then close the soft keyboard - quite a long-winded
procedure just to change an incorrect choice!

What I would like to do is add a blank to the list so if I have to revert
back to a blank I can just use the stylus to choose a blank from the chooser

How do I add the option of inputting a blank from the Data Validation List
bearing in mind I am using the Data Validation Source box for entering my
choices directly and not specifying a range of cells?

I have tried adding "" and even a space to no avail.

Although not a betting man I would wager there is a simple 'fix' for this
but things are only simple if you know how in the first instance! ;^)

Thanks & regards,

Dear Sir,

If any one could give me a solution for this its will be a great help for me.

I am working in a bank and on every day we receive Month to date data of Loans and advances made by every branch with Region wise total and manager wise total. With Sum of loan and count of loan. In our MIS format the in A coulum branches are sorted and listed in a sequence with sub total Region. I have data where if if do the pivot and change the data the out put should be displayed accordingly in the MIS format. Can any one help me how can we do this or is there any other office addins/softwares are available if so the data is changed on a daily basis and if we do the pivot it will automatically copy the data to the MIS format.


How do I calculate the number of batches per hour? Here's what I have so far:

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")

as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.

I'm trying to format a worksheet to show how many days overdue certain tasks are, and running into a couple of issues. The sheet is set up with Due Dates in Column A, Days Overdue in Column B, and Date Completed in Column C. My first thought was just to use as simple a formula as possible in Column B =Today()-A2. This worked alright for tasks that already had Due Dates assigned, but if Column A was blank I'd get a high number in Column B. I also realized that tasks will continue to show as overdue even after I enter the completed-on date in Column C. Is there a relatively simple way to tackle this formula? Thanks in advance for suggestions. (I've attached an example with the column headings I want to use.)

Hi, this is something so simple that I have forgotten how to do it.
I want F3 to turn yellow if someone selects "Yes" from a drop down list in cell E3, then F3 has no fill once data is entered into it. And F3 turns Black if E3= no selected from the list. Or F3 turns red if E3 contains "TBC"

so in summary,

if E3="Yes", then F3 conditional format to Yellow until data is entered in it.
if E3="No", then F3 conditional format to Black
if E3="TBC", then E3 & F3 conditional format to Red until E3 is changed to
"Yes" or "No" at a later time.

Thanks in Advance for the help


I found this solution for "drop down list with hyperlink" but it did not work.

Perhaps a better solution is to use a workaround that relies on the HYPERLINK function to refer to whatever is selected in the drop-down list. For instance, if you have your data validation drop-down list in cell A1, then you might put the following formula in cell B1:

=HYPERLINK(A1, "Goto Link")

The solution directly above provides exactly what I am looking for
in the field where I write the formula, but it fails to hyperlink.
I have created a drop down list and linked each one of them to a
specific worksheet. When I select them individually they link to
appropriate worksheet. But when I select them in the drop down
list I receive the following error when I select the Hyperlink in
cell B1 as directed above.

"Cannot open the specified file"

Any thoughts?


I use Excel 2000
I have sheet muster for my clients of January, 2005 like :
( P = Present, A=Absent )
Days Sun Mon Tue Wed
Date 1 2 3 4

2 Lucy A P P A
Now I want to calculate the total Sundays, Mondays, Tuesdays etc. present in
that month. How can I do this?
Knowldege is Power

I am setting up a PivotTable and only want to show the actual raw data values in the PivotTable field and NOT any sum, count, average, max, min, etc etc.

How can I do this? I only seem to have the options for sums, counts, etc. There are no options for just presenting the data.

So for example, rather than a PivotTable that results in counts of 1, 1, 1 in each cell, I want it to show Compay1, Company2, Company3, etc.

Hi folks,

Hoping someone can help me quickly as I'm pulling my hair out and have a deadline getting too close.

Been trailing the net and this board but can't work out how to do a simple variance.

How do I work out the difference between two numbers - including negatives.

If the numbers are all positive, it's fine as it's simply a case of A - B = C which is your difference. However, that doesn't work if B is negative.

I need a formula that would give the following:

First Number / Second Number / Difference
1 / 5 / 4
1 / -5 / -6
-1 / 5 / 6
-1 / -5 / -4
-5 / -1 / 4

Hopefully there's a simple function I've been missing.

Thanks in advance, R


I have a long list of data validation. I was wondering if there is a way when I clik on the drop down menu and type the first letter, automatically Excel shows all list with that letter.

Right now, I have to click on the drop down menu and scroll manually until I reach that desired list.


Hi everyone....this is my first post here ....and not my last I believe!

My question I believe is easily solvable for you cracks of excel.
I have a worksheet with a list of rows (item#, date, price, etc). In the last column of this list I can put an x for some of the items.
On another worksheet or sheet, I need to autoamtically have a list of the items in the first list above, that have an X in the last columns.
I created an example on a worksheet attached just for you to understand.
I apreciate all the help I can get.
Thank you so much.

I am trying to automatically capture and record the date of a cell's last change in value (date stamp). I have an item price list and if a particular cell gets updated I want to automatically record the date of change of that cell. I realize that after I change cell A1 I could tab to cell B1 and enter Ctrl+; but if I have a hundred new prices to enter I don't want to do that (plus me or the data entry person might forget).

For instance,

1 $32.17 8/17/08
2 $43.20 9/12/09

If I go in and update cell A1 to $33.98 today I would like cell B1 to read 2/16/10. But I don't want cell B2 to change.
