custom list creator

world's simplest list tool

This is a super simple browser-based application that generates a list of any length and any content. In the options, you can select the type of items that will fill the list, how many items there will be, and the program will generate this exact list. Additionally, you can specify a custom separator character that will go between the items. Created by list geeks from team Browserling.

What is a custom list creator?

This online utility creates a custom list with any number of items in it. For example, you can create a list of increasing numbers "1, 2, 3, 4, 5", a list of decreasing numbers "5, 4, 3, 2, 1", an alphabetic list "a, b, c, d, e", and a reverse alphabetic list "e, d, c, b, a". When you generate an alphabetic list, it uses the alphabetic numbering system is used to generate the letters. It goes from "a" to "z", then "aa", "ab" to "az", then "ba", "bb" to "bz", and so on until "zz", and then it wraps to "aaa", followed by "aab", etc. You can also create a list from custom items you have specified. You can switch between the list type modes in the first block of options. If the custom items mode is selected, you can enter the items that will be used to create the list in the second block of options. Here, each item can be entered on a new line. For example, if you enter three items, such as "item1", "item2", and "item3", and you create a list that has five items, then the three items will be cyclically reused and you'll get a list "item1, item2, item3, item1, item2". In the third block of options, you can set the length of the list (the number of items in it) and indicate the delimiter symbol that will appear between the generated items. Listabulous!

List of Decreasing Numbers

In this example, we create a list of numbers from 100 to 1. To do this, we select the descending list generation mode and enter "100" in the length of the list option. As a result, we get a list of exactly 100 numbers, separated by a comma.

100, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90, 89, 88, 87, 86, 85, 84, 83, 82, 81, 80, 79, 78, 77, 76, 75, 74, 73, 72, 71, 70, 69, 68, 67, 66, 65, 64, 63, 62, 61, 60, 59, 58, 57, 56, 55, 54, 53, 52, 51, 50, 49, 48, 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

Create a Letter List

In this example, we activate the ascending letter list type and create an alphabetical list of 78 items. As you know, there are 26 letters in the English alphabet and to fill the list with 78 items, we use the alphabetical numbering scheme that starts a new counter "aa" after the last letter "z", and similarly after "az" it prints "ba", and so on until it reaches "bz". The delimiter symbol that is printed after each letter is the dot symbol.

a. b. c. d. e. f. g. h. i. j. k. l. m. n. o. p. q. r. s. t. u. v. w. x. y. z. aa. ab. ac. ad. ae. af. ag. ah. ai. aj. ak. al. am. an. ao. ap. aq. ar. as. at. au. av. aw. ax. ay. az. ba. bb. bc. bd. be. bf. bg. bh. bi. bj. bk. bl. bm. bn. bo. bp. bq. br. bs. bt. bu. bv. bw. bx. by. bz

Generate a List from Custom Items

In this example, we switch to the custom list mode and generate a list from our own items. We put 12 types of coffee drinks in the custom items option and generate a list of 24 items. As we only have 12 types of coffee, to generate 24 items, the coffee types are copied twice. The output list uses a vertical bar delimiter for the items.

Doppio|Ristretto|Macchiato|Affogato|Espresso|Latte|Cappuccino|Americano|Cortado|Flat White|Frappe|Long Black|Doppio|Ristretto|Macchiato|Affogato|Espresso|Latte|Cappuccino|Americano|Cortado|Flat White|Frappe|Long Black
