List Unique Values Of Multiple Columns

Mar 12, 2008

I need a UDF to make live easier. I have a huge excel file and I need a final function (I suppose a UDF) that lists all values from a range spanning over multiple columns and rows. I would not really like a macro, since it does not update when certain values are changed.

It's part of a bigger functionality, but I need this one, really bad, since it spans over 6000 rows as the search range, and 7000 as the search values. In short:
I got to list all the unique values. They are in specific cells on worksheet 1 (A1:C5 and A25:C31) and should be listed on worksheet2 starting in field A2. As 'simple' as that. Nothing more, nothing less, just list all unique values of a certain range, which I specify. If it can not be done, by selecting the two fields separately, it's no problem at all to list all values in eg A1:C6000. Do note that some of the cells will be blank, and I don't need blanks. I only need the actual data sets. I added a sample excel file, that shows a representation of the data. I can not upload the actual file, since it's way too big (60 MB). So a sample file should give you the idea.

Three sheets:
Data 1: some value lists multiple columns
Data 2: some value lists, again multiple columns
Desired result: the result as it should be listed.

Make A List Of Unique Values Using 3 Different Columns?

Feb 26, 2014

See attached file with a smaller sample of the 1667 row table of data I am working with. What I am looking to do is make a list on another sheet of each every line with a county and have the corresponding Township and range with it. So if I have a cell and I select Audubon county, I would like a list to populate that has the 12 lines of Audubon county in column A, and the Township in column B and the Range in column C.

Create 1 List Of Unique Values From 12 Columns Of Data

Apr 28, 2014

I have a spreadsheet of 12 columns (A to L), with a list of student names under each down to row 31. Each column represents an after-school club that the child can attend.

However, a child can sign up to multiple clubs, so their name can appear in several places across the spreadsheet.

What I would like to do is have a 13th column which is an overall list of students who have signed up to at least 1 club, i.e. their name appears at least once in columns A to L.

How do I achieve this so that only unique entries are listed and duplicates are removed in this 13th column?

Getting Unique Values In Multiple Columns Using Formulas

May 13, 2014

I need to list only the unique values in a range found in multiple columns. Some cells are blank. I need to list all the unique values in numeric and/or alphanumeric order in another column within the same worksheet. I would prefer non-array formulas, if possible. See the attached file.

In the attached table, I have 5 columns and 5 rows of values in the range B2:F6. The unique values, in order, are 0, 1, 2, 3, 4, 5. This looks simple and can be done manually if the file is small but I have 150 columns and 150 rows, thus the need for automation.

Collecting Unique Values Of Multiple Ranges Into One Master List

Dec 20, 2012

I gather two lists of serial numbers (i.e.) from two different sources; one populated in sheet1, A:A (with variable row numbers) and the other in sheet2 B:B (again with varying number of rows)

I am trying to gather a master list of unique serial numbers in sheet3, C:C.

So far I have tried advanced filter, union.range, etc. but couldn't figure work it. I guess some of these columns need to have names assigned to it and have a header.

Creating Unique List Of Values From Column Of Data Across Multiple Sheets No Blanks

Jul 8, 2014

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.

Excel 2010 :: Produce Unique List Of Key Values With Second Values Concatenated Together

Sep 15, 2013

I have some data with recurring key values and differing values in the second column, I need to produce a unique list of key values with the second values concatenated together.(See below)

The data can be 10 rows to 5000 and I can have anything from 5 to 150 sheets (Separate data sets), a macro would go a long way to keeping me sane.

Sample data Required Output
A | B Z
1| 10 | a 10,a,b,c
2| 10 | b 11,a
3| 10 | c 12,a,b
4| 11 | a

Formula For Obtaining List Of Unique Values But Not Including Values Which Contain IC

Aug 14, 2014

1. Using a formula, I am trying to to obtain a list of unique values (string) (caveat: see #2) from the range E2:E10000 (arbitrarily chose 10000 - the row number is variable)(see #3).

I currently have a formula that seems to work for this purpose but I don't know how to add the condition in #2 (below)

2. To include all unique string values except those starting with the letters "IC"

3. Is there a way to make this formula so that it can only seek values up to the last row, and not go to the 10000th row if not necessary? The E column has no empty cells until after the last row that contains data.

Here is the formula I currently use which serves #1 (above):

[Code] .....

Any way to improve/simplfy this formula for the purpose describbed in #1? How can I add the condition in #2? Can you see a way to include #3? The most important issue here is #2.

Example of desired results:

Column A | Column B
AA | AA
DD | CC
AA | DD
CC |
DD |
DD |
IC |
IC |

Count Unique Values In Column Based On Values In Other Columns

Mar 14, 2014

I'm running into an issue trying to calculate unique values in a Data column based on a few variables in other columns.

My current formula in Summary tab D4:D19 is
{=SUM(IF(FREQUENCY(IF(Data!$I$3:$I$66<$E$1,IF(Data!$A$3:$A$66=$H$1,
IF(Data!$C$3:$C$66=A4,ROW(Data!$I$3:$I$66)))),ROW(Data!$I$3:$I$66)),1))
+
SUM(IF(FREQUENCY(IF(Data!$I$3:$I$66<$E$1,IF(Data!$A$3:$A$66=$I$1,
IF(Data!$C$3:$C$66=A4,ROW(Data!$I$3:$I$66)))),ROW(Data!$I$3:$I$66)),1))}

This is currently counting the number of times a date value (data column I) appears for that name (A4:A19) in the data when meeting all of the conditions. I need it to instead count the number of times a unique date appears for that name with the additional conditions met (which all appear to work fine).

The results in the pink highlighted cells (Summary column D) should be:

Names starting with A - 3
All others - 2

I've left some other columns in the data with X's so that I can easily convert this back to my working spreadsheet.

Look Across Values In 12 Columns, Return The Number Of Unique Values

Apr 17, 2009

I have 12 columns of data. In those 12 columns of data I have 3 digit numeric IDs. I want to count the unique number of IDs for each row. I have about 14K rows.

What would be the best way to do so?

Some rules about how the data is stored. I have 12 columns of data with anywhere from 1 to 12 columns having data for each respondent. Data always fills left to right and never skips columns.

I have attached an example file that represents how the data is stored and the output I would like (Unique Count).

Excel 2007 :: Copy Multiple Unique Values To Multiple Worksheets

I have an Excel Spreadsheet (2007) that contains over 500,000 records that shows Electric meter usage per month over a 24 month period per meter. What I want to be able to do is to select a meter row per number and copy is to it's own worksheet. At the end - I want to be able to have a seperate worksheet per electric meter number - that I can create a graph. If I go through all 9000 meters and copy and paste into a different worksheet - it will take me weeks to do manually. How can I do this automatically?

Create List Of Unique Entries Based On Several Columns

Jul 27, 2013

[URL] ......

In that file, you can see there is a list of somewhat similar data across 5 columns. Some of the entries are duplicates, some are different by only one character. What I want to be able to do is generate a list of all the unique rows of data, taking into account the data from ALL 5 columns. The list can be on another sheet or simply just further down on the same sheet, that doesn't matter too much.

I could do it if it were just one column of data, but struggling trying to do it with several columns.

How To Produce List Of Unique Values

Jan 21, 2012

I was trying to produce a list of unique values from a much larger list. I'm using this array function -

{=IFERROR(INDEX(Sheet2!$B$2:$B$100,MATCH(0,COUNTIF($B$1:B1,Sheet2!$B$2:$B$100))), "")}

- which is marvellous and gives me exactly what I want. However my test book only has this dragged down 10 rows and already it takes 20-30 seconds to calculate. The real workbook is likely to stretch to several hundred rows, and to make matters that little more complex where I have Sheet2!$B$2:$B$100 this will relate to a completely separate book on a company network.

Is there any more efficient method of creating this list or will I just have to bear with the calculation speed?

Get Unique Values In A List Of Duplicates

Feb 28, 2007

I am confident the answer is no, but is there any formula / combination of formulae that will seek out unique values in a list of duplicates (just like filtering unique records only)?

I have a list of many duplicating sales people and I want to just create a column on another sheet that automatically sorts out the unique values (then I will sum their sales numbers with the SUMIF formula).

(By the way, the reason I just don't use the filter function is because the list always changes so I would need to keep applying it.)

Create List Of Unique Values

In column A I have values starting at row 4, ranging up to row 1004.

in coulumn Q (starting at row 3) I'd like a list of unique entries from column A

I know this line is my problem

If Range("A" & I) Range("Q4:Q30") Then
but i'm not sure how to compare against all values in a range

Sub FilterSymbol()
Dim I As Integer
Dim X As Integer
X = Range("O2")
I = 4

Do
If Range("A" & I) Range("Q4:Q30") Then
Range("Q" & I) = Range("A" & I)
I = I + 1
Else: I = I + 1

7sleep F red

I need to output 4 unique Status before the event sleep. When I say unique it is compared to its previous status. So that would be [yellow,pink,red,yellow]. Notice that I could repeat yellow but not a sequential yellow. I cant use previous formula on listing unique values because I have reference point which is sleep, that i need to lookup from a huge pile of data, and i need a counter to move up. I tried vlookup with countif but i still have to define the max range. The data is huge and my menial skills are limited to excel.

Unique Values In A List That Appear At Least 3 Times (2007)

Jan 16, 2010

=COUNT(

1/FREQUENCY(

MATCH($A$1:$A$50,$A$1:$A$50,0)

),

ROW($A$1:$A$50)-ROW(OFFSET($A$1:$A$50,0,0,1,1))

+1))

I'm looking to tweak this formula to count the number of unique values that occur at least 3 times.

So, imagine that A1:A50 contain 50 last names from the phone book, 27 of which are unique according to the formula above.

Now, further imagine that only 5 of these unique 27 last names appear at least 3 times.

I'm looking for the formula that returns 5.

And (like always), for simplicity and sharing reasons, I'm hoping to find a single formula that occupies a single cell, and does not rely on additional columns of intermediate information.
