Random Numbers With No Duplicates

Jan 30, 2010

I want to set up a column of numbers that will be random without any repeating numbers.

Example: If I set up for 1,000 rows, I would like the random numbers to be 1 to 1,000, but the catch would be to have no duplicates in the column.

It has been several years since I worked with Excel and I am sure this can be done with a macro, but I am not sure how to go about it right now.

Generate Random Numbers In Random Cells

Sep 18, 2009

I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

Random Generator With No Duplicates

Apr 18, 2013

In Column A I have a list of 8 team names.

In column AB I have a list of 28 weeks written in date format.

In column B I'd like to chose one week from the 28 weeks listed in AB at random. But B2 - B9 can not have the same date (ie could not have two dates for the 19th of April).

How exactly is that done?

Alternatively - is it possible to have in Column AA the 8 team names. In Column AB the 28 weeks. In Column A a random team picked from column AA and in Column B a random date picked from Column AB. Both column A and Column B can not have duplicates... There's 28 weeks with 8 teams - therefore I only need 8 unique weeks.

Prevent Duplicates In Random Generations

Oct 3, 2006

How do I keep the same names from coming up on the same column when randomly generated there (I hit f9 and names randomly generate on my sheet)? I'm trying to integrate this fix into =IF(Override!G5>0, Override!G5, Shuffle!A34) formula. That formula is the formula that recieves the randomly generated names into the cells I have chosen. The override is so I can do just that if I dont like the generation of names.

example:

name 1
name 2
name 3
name 1 <---if that happens I want this cell to respond by reshuffling until it equals a name that is not in its column, but just that one cell, not the others.

Generate Random Number With No Duplicates Between 1 And 8 In A Column

Mar 21, 2014

I need the easiest way to randomize or generate team numbers in a league. Using COL A assign numbers between 1 & 8 without duplicates. Then repeat 5 more times. This has to be done on the spot and has time constraints as the players will be waiting for their team assignments.

EXAMPLE: I have 48 players which will be assigned to 8 teams of 6. I want to randomize the drawing so the same players don't play on the same teams each week. Also to be able to adjust number of teams determined by how many players are present. either 6 , 8, or 10 teams.

How Do You Create A Unique Random Number W/o Duplicates

Feb 5, 2008

I'm needing to generate a unique random value for a database with 3546 cases. The unique random values cannot be duplicates of each other. I tried the =RANDLOTTO function that I learned of in an old post on this board, but that results in "#NAME?" appearing in the first cell. I tried to install the Add-Ins (both the Analysis ToolPak and the Analysis ToolPak - VBA, but nothing seems to happen. Is there another way to generate these numbers?

Optimize Select Random Cell Value Without Duplicates Code

Apr 6, 2013

I have two worksheets. ws1 contains a large number of dates on column 3. ws3 contains around 20 dates on column 3.

I want to pick two dates randomly in ws1 that does not already exist in ws3.

Here is my working code, but it is really slow to process. How to optimize this code? Also I would like to add a function where if the macro is not able to find two random dates that aren't already in ws3 then exit loop.

VB:
Set ws1 = thisworkbook.sheets(1)
Set ws3 = thisworkbook.sheets(3)

lr = ws2.Cells.Find(What:="*", After:=[A1], SearchDirection:=xlPrevious).Row
Set rvis = ws2.Range("c2:c" & lr).SpecialCells(xlCellTypeVisible)
mynodate = 0

[Code] .....

VBA For Random Numbers?

Apr 6, 2014

How can I use a macro on a button in SHEET 1 to generate random numbers on SHEET 2 as follows?

Cell A1: (1-10)
Cell A2: (1-6)
Cell A3: (1-100)

I've got it working with formulas, but every time I press "DELETE" the random numbers jump to new values.

Random Number Between Two Numbers VBA

Jan 3, 2014

I have build a system that needs a lot of random numbers generated to work.

I have used what I thought would work to generate me these numbers like this example:

VB:
Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row
RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)

This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.

However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.

Any way to make say cells A1 thru A10 produce random numbers from 0 to 9.

I would like to do it without a macro if possible. I also need a button to generate those random numbers. I know this button may make it impossible to not use a macro. If it has to be done with a macro then so be it.

Summing Random Numbers?

Feb 23, 2014

I have a process that generates the value X in cell A1 randomly. So I can change the value of X in A1 by clicking on F9. I want to sum a sequence of X values. I can do this by manually copying each X to a row of cells and then summing the row values. But that is tedious. Can the summation be done automatically without being regarded as being circuler?

Random Numbers And 2007

Nov 9, 2008

I am using excel 2007 with XP pro.

I want to include some random numbers in a large multi-tabbed spreadsheet, but I do not want the number to recalculate every time I make another entry on the tab or elsewhere in the workbook. I would like each tab to have one or two random number options, but each should calcualte independently based on their own inputs.

The "randbetween()" function recalcs with every/any change in the workbook.

Specifically, I want to begin with a random percent between 0 and 50% and then add three fixed values (percents) and one different random percent between 0and 30%. then I want to total all of them.

Random % (0-50) + X% + Y% + Z% + random % (0-30) = total %

Random Numbers Not Divisible By 3

Feb 16, 2009

With a formula, how could I generate random numbers between 1 and 100 that are not divisible by 3?

I made this part of a formula that generates the numbers not divisible by 3:

MOD(ROW(INDIRECT("1:100")),3)0

But I am unsure how to use it to help to generate random numbers between 1 and 100 not divisible by 3.
