How can I create non-repeated numbers between 100 and 300 in Excel?
Hi, Ashkan. Thanks for the great question.
What you’re talking about here is creating a “unique series” – and there’s actually a pretty easy way to do it. You didn’t specify any parameters in your query, so I’m guessing that you’re just talking about a series by ones (100, 101, 102…298, 299, 300) right? So what you do is enter the numeral 100 at cell 1A. Then, in cell 2A enter “=a1+1″ without the quotes. This will give you the numeral 101 in cell A2.
Next, the black square in the lower right corner of cell A2, then hold your left-click down and drag to cell a201. Your cursor will probably change into a cross, but that’s okay.
This will give you the unique series that you’re looking for. This trick will also work in Open Office Calc.
I hope that this helps.
