random list creator

world's simplest list tool

This is a super simple browser-based application that generates random lists of random lengths with random items. You can create lists with items made out of random numbers, random uppercase and lowercase letters, and/or custom characters. You can specify a variable-length item count for the list, as well as use random list item separator characters. Created by list geeks from team Browserling.

What is a random list creator?

This online utility creates a list that contains random items. The number of items in the list (its length) can be either a fixed value or a random value. In the options, you can specify the range for the number of items in the list. For example, if you enter the range from 9 to 12 items, then the randomly generated list will contain either 9, 10, 11, or 12 items. If you want to fix the length of the list, use the same number for the start and end values of the range. For example, the range "10 to 10" will generate a list with exactly 10 random items. You can also specify what items the list will be composed of. In particular, you can fill the list with random numbers (both negative and positive), random letters (both uppercase and lowercase), and individual random symbols (both ASCII and Unicode). Each of these choices has a checkbox that lets you enable it and a range that defines the length of the item. For the random numbers, you can enter the minimum range value and the maximum range value. For example, the range -50 to 50 will select random negative and positive numbers (from -50 to 50). For the letters, you can specify how many letters will go in an item. The item length can also be random, specified using a range. Also, you can enter a custom character set, which will be used to fill the list. To do this, enter all characters you want to use for the list items in the text box option and specify the range for the number of characters per item. You can generate only one of these list types or combine two, three, or all four item types together. By default, all list items are delimited by a comma symbol but you can also use any other delimiter character. Moreover, you can also randomize the item delimiter selection by entering several delimiter characters in the option (one per line). Listabulous!

Generate a Random List of Numbers

In this example, we generate a random list of numbers. We select the checkbox for filling the list with numbers and enter the range from -100 to 100. We set the fixed list length to 50 items and separate the generated random numbers with a semicolon.

-83; 83; 98; -98; 30; -33; -96; 80; 85; -94; 23; -52; 96; -46; 45; -61; -32; -26; 30; 20; -97; -45; 24; 12; 55; 5; -68; -46; -69; -35; -26; -87; 88; -68; 78; 17; 55; 60; 5; -34; 51; -30; -93; 67; 99; -36; 13; -44; 98; -71

Create a Random Letter List

In this example, we generate two types of items at once: random lowercase letters and random uppercase letters. For the small letters, we enter the range [10, 14], which instructs the program to create items with variable lengths from 10 to 14 symbols. For capital letters, we use the range [4, 6]. This range makes sure the capital letter items are no longer than 6 symbols and no shorter than 4 symbols. We also make the list itself to be of variable length with 16 to 18 items. We separate the generated items with a newline character so the output is a column.

Random List from Unicode Charset

In this example, we switch on the custom character mode and generate list items from a pre-defined set of characters. We use multiple Unicode clock glyphs and randomly select them individually or in pairs. The length of the random list varies from 8 to 12 items and the item separators are also selected at random from the set of wave symbols "∼, ≈, ≋".

A Hundred Zeros

This example shows an unusual use-case of this utility. Here we generate a string of one hundred zeros. To do it, we set the random number range to be from 0 to 0, which means only the zero can be selected and we set the random list length to be from 100 to 100, which means that the list length is exactly one hundred items. As a result, the output contains one hundred zeros all joined together (because we left the join character option empty).

Dash Separated Alphabet Letters

This example generates a list that contains individual alphabet letters and it uses the dash symbol as the item separator. In the random list, there are anywhere from 20 to 30 letters.

Generate a List of Random Passwords

This example generates a list of ten highly secure passwords with a length from 12 to 16 characters. To generate them, we selected the custom symbol item type, entered punctuation symbols and lowercase and uppercase letters in the custom character set field.
