Count Duplicate Rows And Produce Count #

Jul 21, 2008

I have a spreadsheet of over 15,000 lines of student information, sorted by student number. I want to count the number of rows which have a duplicate student number, up to 15 duplicates in a row, and show the total number of duplicates in a Separate Column. I.e.

Column 1 Column 2
Row 1 - 200101 3
Row 2 - 200101
Row 3 - 200101
Row 4 - 200102 2
Row 5 - 200102
Row 6 - 200103 1

I've been trying to use a Countif formula, but I found I had to use so many ANDs and ORs that the formula became too long. I don't know how to use programming code, only formulas in Excel. Is there an easier solution using some type of SUMPRODUCT code?

Count Duplicate Rows Then Delete Duplicates

Mar 15, 2009

I have two columns of data, and I need to create a third column to count the number of times that same line appears in the document (and then remove all but the first copy of that line). my data looks as follows (and it is sorted so all duplicate rows appear directly next to each other):

Adam1998 | Jan
Adam1998 | John
Adam1998 | John
Adam1998 | Paul
Adam1998 | Peter
Adam1998 | Peter
Adam1998 | Peter
Adam1999 |John
Adam1999 | Paul

I need this to look as follows:
Adam1998 | Jan | 1
Adam1998 | John | 2
Adam1998 | Paul | 1
Adam1998 | Peter | 3
Adam1999 |John | 1
Adam1999 | Paul | 1

Duplicate Rows Based On Cell Count?

Nov 3, 2011

a quick macro/VBA project that would allow my to duplicate existing rows based on the count in one of the cells. For example, my data currently looks like this:

Cells.Rows.End(xlUp).Count - Insted Of - UsedRange.Rows.Count

Mar 24, 2008

I used Sheets(1).Cells(1, 1).Rows.End(xlUp).Count instead of UsedRange.Rows.Count in this code , but it didn't succed with me. Why and how to do that

Dim i As Long, j As Long
j = 1
For i = 1 To UsedRange.Rows.Count
Sheets(2).Cells(j, "a").Value = Sheets(1).Cells(i, "a").Value
Sheets(2).Cells(j, "b").Value = Sheets(1).Cells(i, "b").Value
Sheets(2).Cells(j, "c").Value = Sheets(1).Cells(i, "c").Value
j = j + 1
Next i

Count Duplicate Cells Only Once

Aug 16, 2006

I have attached a spreadsheet where I need the cells B2 to B8 to return the number of Y/P's (in column D) by Unit (in column E). There are duplicate entries in column D, however, if entry is duplicated, it is only to be counted once. Is there a formula to be able to do this? I don't know anything about VBA so would prefer a formula if possible.

Count & Delete Duplicate Data

May 30, 2007

macro that takes the number data and if it is the same number as in the previous row(s) just delete the extra number(s). It also needs to put in a factor in the next column of how many times the number was the same. For example:

Number Factor
5.67 1
5.70 1
5.77 1
5.77 1
5.77 1
5.77 1

Would become

Number Factor
5.67 1
5.70 1
5.77 4

I tried to make this question as clear as possible.

Merge Duplicate Entries For Count Or Sum

Jan 16, 2008

I often need to merge multiple occurences of data (such as account numbers or names) and to sum or count the values associated with each invividual instance (eg cost or number of entries). Data can often be thousands of rows and varies every time. For example:

Col A Col B
Ken 5.9
Ken 12.6
Brian 5.5
John 6.4
Fred 9.9
Fred 11.6
Fred 2.0

I need to be left with either a sum

Ken 18.5

Combo Box Listing W/ Duplicate Count And Search

May 20, 2009

I'm trying to make a combo box that lists only unique entries in 2 columns but also has a count in brackets beside the entry. For example:

Apples (8)
Bananas (13)
Grapes (2)

The code I have to populate the box is:

Sub RemoveDuplicates()
Dim AllCells As Range, Cell As Range
Dim NoDupes As New Collection
Dim i As Integer, j As Integer
Dim Swap1, Swap2, Item

Set AllCells = Range("e3:f370")

What can I add to count how many times an entry is listed in my range? Also, the filter works off text from the combo box, how can I remove the counts prior to filtering? Here's what I'm using now to filter:

Private Sub SrchBtn_Click()
Worksheets("sheet1").Range("b1") = ComboBox1.Value
Range("A2:J1000").AdvancedFilter Action:=xlFilterInPlace, CriteriaRange:= _
Range("L1:M3"), Unique:=False
ActiveWindow.SmallScroll Down:=-5
Unload Me
End Sub

Count Highest Number Of Duplicate Text Entries In Range

Nov 2, 2011

I have a column that is filled with different names. Some names appear more than once. There is one name in fact that appears four times.

I am looking for a formula, or VBA if that's necessary, that will look through the range Y2:Y50, and return a value of 4, because the person that has the most duplicates, her name appears 4 times.

If everyone's name appeared only once, except for a person whose name was in that range twice, then the formula would return a 2.

Count Unique Values Based On Duplicate Status In Another Column On Filtered Data

Mar 5, 2014

I am able to quite easily count the number of specific values in a cell after the table has been filtered. However, the problem I have run into is that some times the data needs to be placed into the spreadsheet twice (or to be more specific the same subject is associated with several unique data points).

What I need: some way to count the instance of some give value in column D only once based on the presence of a duplicate (unique) identifier in column C. However, when I filter the entire database, it must count *only* the filtered cells and not the hidden cells as well.

Column C Column D
111111 M
111111 M
111111 M


Currently calculates: M=9, F=2

Right now it incorrectly states there are 9 "M" from column D when it really should be 5 since 3 are duplicate values. My main difficulty is making sure this continues to work after I filter the entire sheet (say column ZZ) and have a bunch of hidden cells.

Equation currently using to count only filtered values (in this case "males" and "females"):
="M = " & SUMPRODUCT(SUBTOTAL(3,OFFSET(D3:D13,ROW(D3:D13)-MIN(ROW(D3:D13)),,1))*(D3:D13="M"))

Count Number Of Equal Cells With A Prefix In Col D And Insert Count In Col A?

Aug 7, 2013

I need to count the number of equal cells in col D beginning at the top of the column. The counted cells must begin with a text prefix of "Category:" without the quotes.

Some but not all of the cells in col D begin with a prefix of "Category:" without the quotes, followed by a word or words following the word "Category:" See examples below. All of the terms prefixed with "Category:" in col D are in alphabetical order. I need to count the number of identical cells in col D with the "Category:" prefix.

Examples of the contents of cells in col D with the "Category:" prefix are as follows:

Category: Adversity
Category: Answers
Category: Assurance
Category: Blessings
Category: Build
Category: Change
Category: Children
Category: Choices

Cells above and below cells with a prefix of "Category:" in col D are not adjacent.Cells above and below cells with a prefix of "Category:" in col D are separated by 3 to an undermined number of rows.

I need to count the number of equal cells in col D and insert the count in col A at the last equal term. For example, col A above would have 93, 1, 1, 5, 10, 8, 3, and 12 inserted into col A.

Formula That Adds Count But Saves Count So Can Clear Field

Jan 20, 2008

I want is a field (e.g Large Parts Used) where I can enter in a number, then basically this number is subtracted from current stock field for Large Parts so I get an updated field of current stock on hand.

But what I want to do is once I've entered the number in the Large Parts used field, I can then clear that field but have the corresponding Current stock field to maintain what was last enetered.


Large Parts Current Stock = 50

(enter in) Large Parts Used = 2

Large Parts Current Stock = 48

(Clear field where 2 was entered into Large Parts used)
(Field still stays at Large Parts Current Stock = 48 although field where 2 was entered was cleared, so need it to save the information so can continually clear and re-enter amounts and have the stock continue to reduce)

The attached example explains things a lot better.

I am going to have 2 formulas. 1 for the "Big" group and one for the "Small" The formula needs to look first at the column that has the group in it. Then it needs to count everything is column A excluding "Snake" And return the value.

Count Function To Count From A Set Point On Recurring Basis

Jun 22, 2009

I want to count from each cell that doesn't contain "0". So if cell C2=100, I want to be able to count the number g1*2 from that cell and return a value. But then I want to start another count from c5 to the number of g1*2 and then another count from c8 etc basically any cell that contains a value other than "0", I want to start a count from.

The point of this is that the half life will expire after that count, so I want to be able to add the drug levels on an ongoing basis until the count of the half life has been reached. But there will be further dosing along the way before this half life is reached and these values need to be added to the existing value until the half life expires.

Count Intervals Of 2 Numeric Values In Same Row And Return Count Across Row

Sep 23, 2005

I require a Formula to calculate the INTERVALS (the number of Rows between
the LAST instance and the PREVIOUS instance in a column) between each
individual occurrence of any designated PAIR of Numeric values (single-digit
/ double-digit) in the same Row of the Named Range "Results" and return each
calculated INTERVAL result to a separate Column on the same Row of a New
Sheet - starting with the most recent ( the LAST) occurrence.

For instance, each time 80 and 87 appear together in the same Row, return the
INTERVAL by calculating the number of Rows between the LAST instance and the
PREVIOUS instance in a column - locate when both Numeric values LAST appeared
together and Count back to their PREVIOUS appearance together to get the
required Count; i.e. count from the Row ABOVE LAST appearance to the Row

The results are returned to a chart / matrix layout: I have the criterion
vertically and horizontally and they are referenced using the horizontal and
vertical cell address that houses each criterion, and the results are
returned across the Row of the intercept of the vertical and horizontal
criterion. At some point both criterion values being referenced will be the
same, can the Formula return empty text "" when this occurs?

Example Chart / Matrix Layout:
Cell Ref. A2 and B1 criterion 80 and 80
Cell Ref. A3 and B1 criterion 81 and 80
Cell Ref. A4 and B1 criterion 82 and 80

Criteria B1 houses 80
A2 houses 80
A3 houses 81
A4 houses 82
A5 houses 83

I believe I need a loop code to do what I need, because none of the functions I've tried have worked. I want to start at B2 and go down the column until I come to a YES. When I find a YES, I want to know the number of NOs that preceded it. Then I want to go from that YES(#1) to the next YES(#2) and count the number of NOs between YES(#1) and YES(#2) and so forth, until I run out of rows. For example, in C5, the answer is 2, because there are 2 NOs between YES#1 and YES#2 in coulmn B, and a 1 in C7, because there is 1 NO between YES(#2) and YES(#3) in column B.
