Unique Code Generator
With a QR Code Generator a QR Code can be created within seconds and in three simple steps. At first, choose the function for your Code. Secondly, enter the content that you want to provide your customers and optionally give it a unique look by adjusting the colors and uploading a logo into it. UNIQUE VOUCHERS. Let’s start with the most obvious - you clearly don’t want your vouchers to be easily forgeable. The key to generating hard-to-guess coupon codes is a large set of possible codes where only a small fraction of them are actually valid.
How can I auto generate number if 1 of the column is fixed with the number that I want and another column randomly generate the number that is not in first column? I do not want any duplicate.
For example: I need to auto generate 1-10 into 2 columns. Column A (fixed number)
Column B (random number)
Dil dil pakistan mp3 download. to generate that didn't appear in column A?
Column B should have 2,7,8,9,10.
With this formula, I am able to generate unique number for 2 columns from 1 - 10 but now if I want to fix the first column, how should I code to make sure that number in the 2nd column do not have duplicate from Column A?
The purpose of the 2 columns is for me to do comparison between current session & next session. I was thinking to generate the random number and use INDEX to retrieve the name but first I will need to get the number in the separate rows and not getting any duplicate.
Col B/C/D are like the information of the personnel.
Col A, I am able to manually key in the total of personnel which will affect Col L/M/N. If I have 10 personnel, the column L will change according to 5 groups and Col M and N will change according.
For now with my formulas, I am able to auto shuffle the number for Col M and N based on what I have insert on column A which is 20. This can be change.
What I have problem to have shuffle on the number on M without having duplicate on number that appeared in Col N.
Random/ Shuffle thru 10 number are just an example. The list can go down to more than 50. Possible to auto generate the remaining number instead of manually key in?

First you need to write the random numbers of column B in a new column H for example (H1=2, H3=9..H5=7), leave Column A with your choice and B for the generated numbers.
In I1 write =Rand() and drag it down to have 5 rows with random numbers <0
in J1 write the following formula to Rank the Rand() numbers of column I:=RANK(I1,$I$1:$I$5,0)
drag it till J5 you will have 5 numbers between 1 and 5
In B1 write:=OFFSET($H$1,J1-1,0)
and drag it down till B5, you will have the remaining 5 unique numbers randomly.
Update
You can combine the formulas Rank and Offset together and write in B1:
`=OFFSET($H$1,RANK(I1,$I$1:$I$5,0)-1,0)'
Notice that Rank works on Rand() in column I and not on H where the numbers are.
