Randomly Sorting List Of Numbers Into Different Permutations

Mar 1, 2014

with this problem (which I've been trying for weeks to solve).

I have a column ("C") of 640 numbers, which I need to randomly sort and place into the adjoining (ten thousand) columns. I then need to correlate each of these 10k columns with column "B".

The problem I have with the attached (which works for small numbers), is that when I increase the table size to 640 rows and anything more than a dozen or so columns, it takes forever to calculate and Excel often crashes.

Sorting A List Randomly, And Fairly.

Jul 17, 2007

I have a list of potential competitors in an event, and am using both RAND and ROUND to sort them into a list of 1's and zeros. My formula is as follows: =ROUND(RAND()*1,0). My problem is that I get an uneven distribution of players, out of a list of forty, I may have 38 people that are 1's and 2 people that are 2's. I'd really like the list to be randomized, but evenly to allow for fair competition.

List Permutations Of FOUR Groups From SEVEN Numbers

May 21, 2013

I have SEVEN numbers and FOUR groups.

What I would like to do is list ALL the PERMUTATIONS of those SEVEN numbers in FOUR groups.

So basically, the groups would look like...



...and EACH group would add up to SEVEN etc.

I think there are a total of 840 different PERMUTATIONS available, from anything from 0 numbers in a group to 7 numbers in a group.

I need ALL these groups listed individually .Is there some code that will do this?

Sorting List Of Numbers - Some Are Larger Than Others

Jun 7, 2013

I'm having some problems sorting a list of numbers that some are larger than others, but it would sort it by how large the number is in regards to 123 or 45... 45 would go first instead of 123... I tried to change the column to numbers but it still won't work. as well as in the custom sort section. I'll try to upload a sample...

Sorting A List Of Numbers By Multiple Columns

Oct 13, 2008

I want to sort the list like this:

1) If there is a zero (null) value in all 3 months, these records should be at the bottom sorted by record name (I did not show this field in my file).
2) If there is a non-zero (non-null) value in any of the 3 months, the records will be sorted with each other by total change.

Is there a way to do this without me doing sorts multiple times and manually moving rows of data around (which is what I have done to arrive at the list I have attached)? I am not experienced with VBA or Macros, and would prefer a detailed explanation if a solution is using either method.

Excel 2007 :: List Of Numbers Not Sorting Correctly?

Oct 29, 2013

Using Excel 2007, I have a very simple spreadsheet made up of only two worksheets that I am using to track the songs played by a band during a current tour.

One worksheet is called "Summary" and the other is called "Setlists". In the Setlists worksheet I list every show played (10 shows so far), and every song played from each show. In the Summary worksheet I have very song listed that has been played during the tour in one column (A), then the number of times that song has been played in another column (B). Column B, the number of times each song has been played, is populated by a COUNTIF function that looks at the Setlists worksheet and counts each instance of each song.

What I want to do, very simply, is to sort on column B in order to display the list of songs from the most played to least played. That is where I run into a problem. When I sort my list of numbers, I end up with a seemingly random list that certainly isn't from most to least and I can't figure out why.

Is it possible that the COUNTIF function which populates that column of numbers is somehow throwing off the sort?

Permutations Or Combinations Of A Set Of Numbers

Mar 11, 2009

I want to output every combination of a set of numbers. These permutations must include combinations that use only a few of the numbers as well as all eight...ie.

as well as 1,2,3,4,5,6,7,8

The macro below is from
This only produces combinations using every number. I'm not sure how this macro works but hopefully someone with better know how could run with it or break it down for me!

I only need to achieve this once but am pretty sure doing it manually will cause error and or madness

Dim CurrentRowSub GetString() Dim InString As String InString = InputBox("Enter text to permute:") If Len(InString) < 2 Then Exit Sub If Len(InString) >= 8 Then MsgBox "Too many permutations!" Exit Sub Else ActiveSheet.Columns(1).Clear CurrentRow = 1 Call GetPermutation("", InString) End IfEnd SubSub GetPermutation(x As String, y As String)' The source of this algorithm is unknown Dim i As Integer, j As Integer j = Len(y) If j < 2 Then Cells(CurrentRow, 1) = x & y CurrentRow = CurrentRow + 1 Else For i = 1 To j Call GetPermutation(x + Mid(y, i, 1), _ Left(y, i - 1) + Right(y, j - i)) Next End IfEnd Sub

Permutations For Defined Numbers

Dec 13, 2007

I have a set of numbers 1-24, what I would like to have is to list every 4 set combination of 24 numbers. I believe this is 10626 combinations. I would like the combinations to display in seperate cells.

For example: Rows 1, column 1, 2, 3, and 4 would look like 1 2 3 4. No two numbers can be the same within that row. Row 2 would have 1 2 3 5 and so on untill all possible combinations are exhausted.

How does one do something like this within excel?

Also, I would like to be able to change the value of 24, so instead of entering 24 I could say I have a set of 32 and want a list of 4 or 3 permutable combinations. I want to be to make this as custom as possible.

Permutations Of A List (groups Of 3)

Aug 31, 2007

Is there any way to determine all possible unique combinations (or sets) of any 3 strings in a table? I need to make a master set list from a list of strings which could be over 100 elements long.

Once I have a result set, I need to get rid of any groups which have a value contained in another group.

cells A1 through B100 contain:
Item1 45
Item2 50
Item3 98
Item100 75

Result set would contain groups of any 3 item combinations where the corresponding "B" value is within a certain range (between 40 and 80), while also trying to create sets with the lowest possible sum (placed in the 4th column) of the 3 numbers.

One possible combination would be:
Item1 Item2 Item100 170


I need to list all possible combinations, without re-using an element from a previous (lower sum) combination that matched the criteria.

Randomly Pairing Wrestlers In A List?

I want to be able to input wrestlers names and pair them up for 2 matches randomly. Is there any way to do this? I am not advanced in excel, but not a novice either. I need to make sure they don't wrestle the same people in each round. Also there will be wrestlers from the same team, so is there any way to try and not pair them together unless it is necessary?

Randomly Select Varied Amounts Of Data From A List

Sep 10, 2008

I have a list of people in column A and a list of Cities that they have visited in column B.

I need to check some of the cities they have visited monthly but don't want to check them all.

I have attached a sheet as an example (this has been scaled down).

The number of cities i want to check for each person varies each month depending on how many cities they have visited.

For example, John has visited 16 cities and i want to check 5 of them. I therefore want 5 random cities that he has visited to appear next to his name at the top. The real list of data is massive so this would be really useful if it is possible.

I have looked at rand but i can't get it to randomly give me more than one city, and i don't understand how to get it to give me say 5 cities one month and say 8 cities the next month purely based on a formula from another cell.

Sorting A Range Of Numbers?

May 28, 2014

I'm attempting to create a formula that'll sort a range of numbers and then return the corresponding values based on a specific place within the sorted range.

In this case, I'd like the following numbers sorted smallest to largest:

15, 9, 11, 19, 22, 17, 24, 19, 17, 24

The result would return something like:

9, 11, 15, 17, 17, 19, 19, 22, 24, 24

Then I'd like it to return the value based off of the formula in cell U13 & U14. In this case, it'd return the value in the 2nd and the 9th position (bolded above). I tried to use INDEX(), but it's returning the values in the unsorted list. I'd like it to return values from a sorted list. Also, I'm trying to solve this using a formula (not Sort & Filter) or VBA.

Sorting A Table By Numbers

Oct 15, 2008

I have managed to produce a table which uses formulas to calculate the amount of 'points' someone/a team has accumulated over a period of time however it seems that for some reason or another I cannot sort the table into order of 'who has the most points'


above is the final standings but as you can see the 'sort' function isnt working, and if i do any other sort the name of the person and the points no longer correspond... i.e. it ends up putting the names in alphabetical order and leaving all other columns as they currently are, or it changes the points column, leaving the names in the same place...

Numbers Not Sorting Correctly

Jul 31, 2013

I have three columns expressing death dates (date, month, year). The months and dates are finally sorting correctly within the same year, but I have it set to sort by year first.

The column starts off fine with 1860, goes up to 2013, then starts back at 1884 and goes back up to 2009. I can't find any difference between the two groups: there are some of the same years represented, there are blank month and date cells in both. I have a worksheet with birth dates that sorted fine; the only difference I can find is that birth dates only go up to 1997, but the column is formatted as General, so the turn of the century shouldn't be a problem.

I've tried highlighting the whole thing before sorting as well as selecting one cell as usual. I've also tried formatting the column as Text. I can't think of anything else.
