The two columns, then, will be filtered and we will see that the 1 st column where the numbers are in serial order will be distributed randomly. So there is no randomness whatsoever.
If we use it directly it generates random numbers between zero and one. Note that cell A1 has changed. If you are looking for true random data, you can probably use a third-party random number generator such as whose randomness comes from atmospheric noise. I don't think I would have been able to solve my problem. See screenshots: The Insert Sequence Number utility makes it easy to insert unique sequence numbers into contiguous cells and non-contiguous ranges in Excel.

The second column would still contain 2,7,8,9,10. I thought it was cool that it may be that simple.
To fill in decreasing order, drag up or to the left. But then there is no randomness at all. Remember, by default, Excel uses a linear growth pattern to determine these values. I have already tried the vba that references the first cell in column K then adds +1 down, but that does not work because it either produced a duplicate number already used, or every time the macro ran, it would recalculate every cell in column k which would change an order invoice because an order can be deleted from the masterfile but that order still exist in other reports. It passed most of, though not all, TestU01 Crush randomness tests, which are even tougher. Left click on your mouse while hovering your cursor over the plus sign.
Meaning the first time I click the button I'll get the same 4 random numbers, the second time I push the button I'll get the same set of numbers I got the last time I opened the sheet and presssed it twice. Generating random numbers, passwords, custom lists in Excel Random Generator for Microsoft Excel 2016, 2013-2007 Task You need to fill a range in Excel worksheet with data like unique random numbers, integers, dates, passwords, codes, but have little time and no idea what to start with.

I notice Matt's code does not do that which means he assumed you preformatted the column with the required Custom Format. Okay, this quite lengthy technical introduction ends and we are getting to practical and more useful things.
