Display Number Of Occurrences For Each Unique Date In Column?

Mar 26, 2013

I have a column of dates (Column A) with intermittent blanks and I need to display the number of occurrences for each unique date.

This is what I am starting with: (Note= The number of rows varies by project so I need the whole Column A referenced)

Dates
02-24-2013

12-15-2012

Count Unique Occurrences In Column A If Column B Equals Value?

Jul 25, 2014

how to count the unique occurrences in column A based on the value in column B. In the example below, I am trying to count the number of unique names in each state (Illinois=1, Colorado=2, New York=2). I would like the formula to count unique occurrences for the entire column A because I will be adding to the list.

..A.............B............C
John......Illinois
John.....Illinois
John.....Colorado
Alex.....Colorado
Alex.....New York
Steve...New York
Steve...New York

Count Occurrences Based On Unique Values In Another Column

Mar 18, 2013

I've got two columns, one with policy numbers, the other with error codes.

A policy could be in the list more than once, so I'm counting the number of unique policy numbers with the function

=SUM(IF(FREQUENCY(A10:F10000,A10:A10000)>0,1))

I want to count the number of errors that are NOT code 00 or code 21. Because the error codes are saved as text, I'm counting the number of errors with

=SUMPRODUCT((B10:B10000"21")*(B10:B10000"00")*(B10:B10000""))

The problem is that since a policy number could be listed twice, when I count the errors, I might be counting the same policy as an error twice. This means that I could feasibly end up with more errors than I have unique policies, which doesn't work.

What I'd like to do is only count the number of errors that have unique policy numbers. That is, I only want to count an error the first time it is in the list, based off it's policy number. Is that possible?

Here's my sample data: [URL]

Counting Number Of Occurrences Of A Date

Jan 10, 2008

I am running Excel 2007 at work in compatibility mode. My company is in the process of switching to Excel 2007, but not everyone has it, so I save my files in Excel 97-2003 format, so they can be viewed by everyone.

Problem:
I am trying to count the number of occurrences of "dates" between a starting date and an ending date. (e.g., cells B16:B1000 contain dates when a test at work was performed. I want to count all tests that occurred between 12/30/2007 and 1/9/2007.) Please note that the dates cross the new year

More Info:
I have searched this board, found a similar post, and tried the different formulas listed but get a result of "0" (zero). If I try the same formulas at home using Excel 2000, they work. The formula types I've tried include regular and array styles I am led to believe that this is either an Excel 2007 bug (bug??? - Nah, not from Microsoft!), or one of the cute changes between the new and old versions that I keep running across. The last possibility is that I am doing something wrong, which a smart betting man wouldn't rule out either!

Counting Number Of Date Occurrences In Range Of Cells

Aug 13, 2012

I have an excel sheet which is currently 1,100 lines long and expected to increase and has a number of dates in columns W-AO representing the dates in which someone has had an onsite assessment. I wish to report in column AQ if there has been any visit activity in the month, i.e August for this month’s report. Is there an Excel function which will allow for this? Im thinking something like having a drop down list to select the month at the top of the column and then the sheet returns a value of 1 for all lines where a there is a date equal to the month selected?

I guess it is also worth mentioning that the sheet is setup as a table.

Count Number Occurrences Based On Criteria Column

Feb 5, 2013

I get this work a lot and am looking for a much more effective way of working the dataset,

I have numbers like 1.1, 1.2, 1.3 and so on.......
These come under criteria like (1) = 1.1, 1.2, 1.3 and so on.....

I am look for an automated way of doing a count of any number that falls under this criteria, so I want to count based on criteria (1) it would count all 1.1,1.2,1.3 and so on as one count.

I am attaching a sample document to see how it is laid out. [URL] .....

VBA To Find Cell Value In Column And Count Occurrences In Same Row Within Date Range?

Feb 3, 2014

I would like to design a macro that can find a value within a cell in a colunm and copy a value in the row then count occurances of that value next time a match in the colunm is found on a different row, but also do this only if the date range in the row is within a specified range. So a multi-critieria search and copy operation.

To explain a little better here is a simplified example of my spread sheet that is in input for the macro.

A
B
C
D
E

1
PART NO.
date in
date out
comp1
comp2[code]......

Column A lists the coponents found on the same row as the seach critria, in this example "12-3".

Column B lists the number of occurances of the components. This search is limited to a date range input by the user.

So what I can see is the components replaced and the amount of times replaced on a specific item over a fixed time.

*It is difficult to describe this problem without showing the macro output, but this is just an example for the purpose of explanation.

I know a bit of VBA programming and initially I started with an input box that asks for the part number and limit dates.

Display Unique Items That Occur More Than X Times In Column?

Jan 25, 2012

I have a long column of 9-digit numbers which represent the swipe-card-ID's of patrons accessing a parking facility. Most of them occur more than once, some of them many times. There is an operational rule that bars them from using the facility more than x times. (I can't implement this limitation in the parking software/hardware, or I would happily do so.)

So my question is, is there a way to process through that column, identifying each unique ID, and reporting any that occur more than x times?

Count Unique Instances Of Date While Filtering Based Upon Date And ID Number

Aug 14, 2014

I have a list of ID# (Col A) and dates (Col B). The ID # of reference is Col (F) and today's date (Col G). I need to count how many future dates there are in the list (Col B) that are unique and in the future from today's date.

I'm still fairly new to all these formulas and functions which is why I'm not attempting this in VBA.

I've attached an example work book and I would like the result in H2.

Counting Unique Occurrences

Mar 27, 2008

We've got a column of names. A single name might appear once or two hundred times. The column is over 25,000 lines long, so we don't want to have to count how many different users there are (besides the likelihood of doing it wrong!). Is there some way to make Excel count the number of unique entries in the list, ignoring multiple repetitions of the same name?

Counting Unique / Distinct Occurrences With Wildcard

Aug 5, 2014

I'm working with a set of text values. The sets of text can be either 2 or 3 chars long (in this example 2), and are separated with a pipe. The end char for each set of chars in fixed. In this case a Z.

I'm looking for a formula which counts the unique / distict number of sets of chars. I have been trying to use COUNTIF with a wildcard (?Z), but unfortunately I haven't been able to find the correct formula yet.

For example.

|AZ|AZ|AZ|BZ|AZ|AZ|BZ|AZ|BZ|AZ| -> 2 (AZ, BZ)
|AZ|AZ|AZ|BZ|CZ|AZ|CZ|AZ|BZ|AZ| -> 3 (AZ, BZ, CZ)
|CZ|BZ|AZ|BZ|CZ|AZ|EZ|AZ|FZ|AZ| -> 5 (AZ, BZ, CZ, EZ, FZ)
|BZ|BZ|AZ|BZ|CZ|AZ|EZ|AZ|GZ|AZ| -> 5 (AZ, BZ, CZ, EZ, GZ)

List Unique Values In Excel And Count Occurrences Of Each?

May 25, 2014

I realise this is beyond me and wonder if it is possible to list uniqure values in excel and place a count occurrences of each. I have a hugh list of over 400 alpha code i.e ABCD, ABCD, ABCE, BDCE, BDCF ZXYE etc etc. What I'd like to do is pick out all the unique values so I can see what alpha codes are on the list. But then I would also like to count the occurrences of each value/name so I know how many times they appeared on the list.

Col A
ABCD
ABCD
ABCE
BDCE
BDCF
ZXYE
ZXYE
YEZY
CDEF

Col B is where i would like to list all the unquie vaules with a count e.g.
ABCD 2
ABCE 1
BDCE 1
BDCF 1
ZXYE 2
YEZY 1
CDEF 1

Loop Through Log / Extract Unique Name And Populate Table With Occurrences

Feb 25, 2014

Working on data presentation. I have a log that is populated from elsewhere in the workbook. I would like to be able to have a table update itself as the log changes. In the table I need to capture each unique name and all dates associated with the name. I have a sample attached of what I hoped it would look like when working. Basically I have a place for the name and to the right, cells that represent the months of the year. The data captured has the date in mm/dd/yyyy format and I just need each monthly instance to land in the proper month column in the table. No need for date specific, just the month of the occurrence.

Extract All Occurrences Of One Name And Display Data On New Sheet

Mar 26, 2014

I would like to extract from a massive list of names, all occurrences of one name and display the data on a new sheet.

For example;

Name Date Location
James 23/04 edinburgh
Jimmy 28/04 london
David 03/05 Belfast
Sarah 08/07 Glasgow
David 12/09 Birmingham
James 13/01 Manchester

So the output on the new sheet would be;

Name Date Location
James 23/04 edinburgh
James 13/01 Machester

I basically want to find where James has been and on which dates without having to scroll through 1000's of names.

Count Unique Occurrences Based On Multiple Conditions In Another Cells

Sep 19, 2013

I am trying to count the number of unique entries in a sheet, that also satisfy 2 other conditions.

I've attached an example sheet : Example email report.xlsx

The result I need is: The number of unique values in column E, that also have NULL in column G and NULL in column I.

So, in the example, the result would be 7.

I know I can do this by conditional formatting and filtering, but would prefer a formula, and perhaps also a macro that I could apply as the number of rows in each sheet is up to 20000, and each month's sheet will be a different size.

Display Number Of Years Based On A Date

Mar 28, 2009

Right now, in a column I would like to display an number (length of employment) based on the hire date.

In one cell the employee's hire date is entered. In a column of other cells the pay period ending date is displayed and in another column the length of employment is displayed.

Example:

03/17/2000

03/01/2009 8
03/15/2009 8
03/29/2009 9
04/12/2009 9
04/26/2009 9

How would I create a formula in the length of employment cells that would indicate the correct number of years based on the hire date and adjusts when the pay period date passes this hire date?

Compare General Number To Date - Display Based On Criteria

Apr 29, 2007

I would like to create a formula that compares a number in one cell to the dates I have displayed in two different cells. If true, then I want it to display the Currency value from another cell.

______A________B________C________D_____
|1| Due Date | Amount | 1/01/2007 | 1/15/2007
|2|___4________$98_______________________

A2 is the DAY it's due
B2 is the AMT that is due

I can create an IF...THEN statement where if A2 is >= C1 BUT less than D1 then the value is B2, BUT it only works if I change A2 to an actual date which means i have to change it every month...which would not help with forecasting future transactions. So in the example above, the value would be in C2 and not D2.

Count The Number Of Unique Numbers In A Column

May 4, 2006

i'm currently trying to count the number of unique numbers in a Column using this formula:

=SUMPRODUCT((A3:A3002<>"")/COUNTIF(A3:A4002;A3:A3002&""))

So far so good.....But I want to add some conditions like only count the numbers that meet the condition say N1:N3000="SE*"

=SUMPRODUCT((A1:A3000<>"");(AND(OR(N1:N3000="SE*";N1:N3000="INC*")/COUNTIF(A1:A3000;A1:A3000&""))))

On this one I get #VALUE! and i can't figure out why.

I have also tried to put the AND/OR condition before the actual starting of the array of the SUMPRODUCT but nothing.

Counting The Number Of Occurrences Before The Current Week Number?

Jul 10, 2014

I have a spreadsheet for tracking jobs. Most everything is based off of week # rather than date. I am trying to get the stats page of the workbook to tally the total number of late jobs per week.The current week is taken care of because there is a function that automatically displays on time yes or no and I just set it to count the yeses or nos.The problem I am having is for past weeks.

I tried- =COUNTIF(Table2[On-time],"No"+(CountIF(Table2[Week # Hidden],"<Weeknum(Now())" but that doesn't work. I also tried isolating the < like this. =COUNTIF(Table2[On-time],"No"+(CountIF(Table2[Week # Hidden],"<"Weeknum(Now()) and that did not work either.

------ UPDATE

In response to using CountIFS I have also tried-

=COUNTIFS(Table2[On-time],"NO",Table2[Due Week '# Hidden],"<Weeknum(Now())") this just returns a zero value even when I have a late job listed three weeks ago.
