Tips to get the most out of it
Highest to lowest
If the first number is greater than the last, the list counts down. The step is always positive: the direction is decided by the order of the numbers.
Codes and references
With zero padding and a prefix (“REF-” + 001, 002…) you can generate a series of references, order numbers or file names.
For spreadsheets
Separate with line breaks to paste into a column, or with tabs to paste into a row.
Decimals without errors
With a step of 0.1 the list comes out clean (0.1, 0.2, 0.3) without the typical leftover digits that decimals produce in computing.
Frequently asked questions
How do I generate a list of numbers from 1 to 100?
Enter 1 in “First number” and 100 in “Last number”, with a step of 1. The list appears instantly and you can copy it.
How do I make a list counting by 5s?
Set the step to 5. From 0 to 100 you will get 0, 5, 10, 15… 100.
How many numbers can it generate?
Up to 100,000 per list. If the range gives more, it is trimmed and we let you know.
Is it the same as the random number generator?
No. This one generates an ordered, predictable sequence; the random generator picks numbers at random.
