Creating Unique IDs For Repeat Occurrences
Jun 2, 2014
I need to create unique numbers for the below info
ID. Date
349-006 02/06/14
349-006 02/06/14
349-006 02/06/14
349-006 04/06/14
349-006 04/06/14
The first 3 rows would have the ID of 1 because they share the same date but the other 2 rows would be ID of 2. And so on..

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?

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)

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

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.

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]

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.

I'm trying to write a formula that will count the number of unique occurrences in a column, if a specified value is found in a different column.
So I want to count the number of unique values in the "ID" column if let's say the text "NameA" appears in the "Name" column.
ID Name 12345
NameA
NameB
NameA 12346

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.

I have to create ranges of unique numbers that follows the below rules.
1) Have to start with 3 standard digits (ie 101 or 102 etc)
2) The total length of the is has to be 10 digits (ie 1010123456)
3) The second part (the last 7 numbers) must be unique!
4) Can create a lot of numbers (more that 5000 rows)
5) thats all with the unique numbers
Continue,
Somewhere in the sheet has to be a search function to find where a specific id is located, make it red and copy/cut in to another sheet.

I need to create unique IDs for all of my stock. I would like to use the concatenate function so that the first letter of each products type is taken and then joined onto a unique number. Im not sure how I will do this I was thinking that the formula looks at the largest value and adds 1 so that there are no duplicate numbers added to the first letter of the product type. E.g. the first mother board added will be "M1" the next will be "M2" as the formula has found that M1 exists and has added 1.

I am attempting to create a unique list on column B of tab "1" from columns B of tabs "2" through "5" for which i have the following array formula thus far,
=IFERROR(INDEX(??3Dreference??, MATCH(0,COUNTIF($B$3:$B3,??3Dreference??),0)),"")
I've attempted to list my tab names somewhere on the sheet and inserting this into the previous formula,
INDIRECT("'"&$P$4:$P$7&"'!B3:B300")
However this will only return the first value from column B on each tab and I'm assuming its because INDEX and COUNTIF do not accept 3d references.

What I'm trying to achieve is the following;
I have a big keyword list saved in Excel.
Something like the following,
These are all keyword phrases;
car rent
car hire
cars for rent uk
etc etc etc
All listed in Column A
All phrases in Column A, and in separate rows.(1 phrase per row.)about 2000 lines (Rows) in total.
What I want to know is there any way of selecting the whole list and exporting it (To save it as another list. A list of just unique keywords?
So, It would create a list like;
car
rent
uk
hire
for
etc etc etc.
So basically I want excell to look at all the words and export them to another list showing just unique keywords, 1 per line.
This is so I can see from a huge list what all the unique keywords are.
Is there a way of doing this within Excel Now?? or has someone made a plugin ( Macro) to achieve this?
I've looked at the sort & filter options, but it doesn't appear to have this function?

I currently have a list of companies. I want to create a unique list of these companies which I can use for some irrelevant purpose. What i did was I started recording a macro in which I first deleted everything in the spreadsheet. Afterwards I copied the whole company list from another spreadsheet and pasted it as values into the new spreadsheet. Afterwards I made an advanced filter; list range being the companies and copied it into a new location after making sure I had said yes to unique only.
Here is the code itself:

I am creating an excel worksheet. Every time a user opens the worksheet (from a template), I want to get the next numeric sequence number as a reference, showing it in the sheet. The template is available to multiple users but the sequence number should be unique, ie if user Tom has sequence 1, Jerry will get 2, then Anne will get 3 and Tom's next one will be 4. I considered an ASCII text file with a number in, eg 1. Upon opening get OPEN text file, READ text file, Convert to numeric.. add 1.. use this. Convert to string.. WRITE text file. It seems clumsy and since I can only open with READ or WRITE (append no good, since I want only 1 value held), the READ allows multiple users to access simulataneously, and potentially get the same sequence.
Is it possinle to:
LOCK file
OPEN file for read
READ file
CLOSE file
OPEN file for write
WRITE file
CLOSE file
UNCLOCK file
There are likely to be several users accessing the template and the chance of them opening it at the same time is limited, but possible.

I need to count the unique for a customer. The areas to be counted are separated by blank lines. At present, I am using sumproduct(1/countif(range1,range1), to count the unique items. This formula works perfectly except that it takes me almost an hour to do this for all the measurements. Is there a macro that can provide me with the same results -- putting the same values where I am presently have the formulas (the cells that before the blank lines)?

I have a spreadsheet with some calculations and the part i am interested in is data in R4 : V58
In this R4:R58, S4:S58 and T4:T58 have some rows that have False because of IF calculations that put False in some rows of R and hence in S and Hence in T.
For example, R15="FALSE" so will S15 and T15 be. Col U is based on whether the corresponding row in R is False or a number. If a Rown in R is false, the row in U= 0 else the row in U is the same as in the same row of a different column - Col I
Col R, T and U are numbers. Col S is text
For example:"
R S T U
False False False 0
False False False 0
False False False 0
55 DEF 3 15
46 XYZ 2 67
False False False 0
False False False 0
23 GEF 4 43
I want a table in another worksheet that will sort through this using a formula and print
Col1 Col2 Col3 Col4
55 DEF 3 15
46 XYZ 2 67
23 GEF 4 43
If I can define things like where the table will be placed in the new worksheet etc, that will be a bonus..But It appears I cannot understand how to do this at all..

I have 6 worksheets in my file. In sheets 1-5, column A2:A26 list people's names. Some people's names appears on more than one sheet. Not all cells are populated with a value.
ex.
SHEET1
COLUMNA
Bill
[Code]....
My attempt was... =INDEX('Week1:Week5-!$A$2:$A$26,MATCH(0,COUNTIF($A$1:A1,"Week1:Week5"!$A$2:$A$26),0))
where the sheets were Week1-Week5 and the values on each sheet was A2:A26. But I think there's an issue with Excel being able to 3D reference for these types of functions.

I know how to use array formulae to create a unique list, i.e.{=INDEX($G$1:$G$760,SMALL(IF(ROW($G$1:$G$760)=MATCH($G$1:$G$760,$G$1:$G$760,0),ROW($G$1:$G$760)),ROW()))}
however this is giving all the unique items from column G and I only want the unique items that have a non-zero value in column H as well. This would be the sumif of all instances that would have to be zero. I've tried to crack it and I've tried to search for solutions but so far no joy.

I'm trying to think of a way to do this. I need a unique ID number per company, so I would want it to look something like this:
0001: Apple
0001: Apple
0002: Google
0003: Sony
0003: Sony
0003: Sony
0003: Sony
0004: Ford
0004: Ford
0004: Ford
.....and on and on for about 400+ rows. I think I know how to state the condition. IF B15 =/= B14 then....assign unique ID, else A15 = A14....or something to that effect.

Each product is represented by a serial number (column A).
The can be sorted on column A from smallest to largest prior to calculating results if that helps.
The repair list contains 1 entry per spare part used, so the same serial number may occur several times.
Furthermore, a product may have been repaired on several instances - so the serial numbers can span several dates (column B).
The solution i am looking for should return the number of unique repair dates per serial number. That way i can see, how many times each product has been repaired. Results can be displayed in an individual column.
Sample list:
Serial........Repair date
207742052008-09-04
207755082008-12-17
207755212008-12-31
