List item counter

World's simplest list tool

This is a super simple browser-based application that adds numbering to items in a list. You can switch between integer, symbolic, and Roman numbering systems, choose the numbering format (for example, a counter with a bracket or with a dot), or create a custom counter format. You can also reverse the numbering, skip empty items, and start counting from zero. Created by list geeks from team Browserling.

List item counter tool What is a list item counter?
This online program enumerates all list items and adds a counter before each item. For example, if you have a list of letters "a, b, c", you'll get a numbered list with each letter's ordinal position appended before it "1. a, 2. b, 3. c". Before adding the numbering, you need to properly separate the list items. Since a list can be of any format, you can delimit its items by a character or a regex delimiter. Select the mode you need in the first block of options and specify a character or regular expression in the textbox. Here you can also specify a separator character for the output numbered list. We have added a bunch of options that let you customize the numbering. First of all, you can choose which numerical system to use for the item numbers. They can be regular integers (i.e. "1, 2, 3, …"), lowercase alphabetic letters (i.e. "a , b, c, … "), uppercase alphabetic letters (i.e. "A, B, C, …"), lowercase Roman numerals (i.e."i, ii, iii, … "), or uppercase Roman numerals (i.e."I, II, III, … "). Additionally, you can choose the numbering format. For example, it can be a counter with a parenthesis (i.e. "1) 2) 3)"), with a square bracket (i.e. "1] 2] 3]"), or with a period (i.e. "1. 2. 3."). If you want to specify a custom numbering format, select the "custom" mode, and specify the numbering pattern using the special notation "%n" for the counter. For example, the pattern "%n: " will generate numbering with the counter followed by a colon, such as: "1: …, 2: …, 3: …", and the pattern "{%n} " will generate numbering with the counter wrapped in curly braces, such as: "{1} …, {2} …, {3} …". The program also has several quick and useful options for skipping counting the empty items, reversing numbering so that the item counter goes from the largest value to the smallest, and starting counting from zero, which is useful for programmers.

List item counter examples Click to use
Enumerate Bengali Numbers
In this example, we decided to learn the Bengali numeral system. To make it easier and to avoid getting confused about the meaning of Bengali numbers, we added regular Arabic/English numbers before each Bengali number. The counter has a parenthesis after each number and starts from zero, and it uses the semicolon character separator in the input and output lists.
০; ১; ২; ৩; ৪; ৫; ৬; ৭; ৮; ৯; ১০; ১১; ১২; ১৩; ১৪; ১৫; ১৬; ১৭; ১৮; ১৯; ২০; ২১; ২২; ২৩; ২৪; ২৫; ২৬; ২৭; ২৮; ২৯; ৩০; ৩১; ৩২; ৩৩; ৩৪; ৩৫; ৩৬; ৩৭; ৩৮; ৩৯; ৪০; ৪১; ৪২; ৪৩; ৪৪; ৪৫; ৪৬; ৪৭; ৪৮; ৪৯; ৫০
0) ০; 1) ১; 2) ২; 3) ৩; 4) ৪; 5) ৫; 6) ৬; 7) ৭; 8) ৮; 9) ৯; 10) ১০; 11) ১১; 12) ১২; 13) ১৩; 14) ১৪; 15) ১৫; 16) ১৬; 17) ১৭; 18) ১৮; 19) ১৯; 20) ২০; 21) ২১; 22) ২২; 23) ২৩; 24) ২৪; 25) ২৫; 26) ২৬; 27) ২৭; 28) ২৮; 29) ২৯; 30) ৩০; 31) ৩১; 32) ৩২; 33) ৩৩; 34) ৩৪; 35) ৩৫; 36) ৩৬; 37) ৩৭; 38) ৩৮; 39) ৩৯; 40) ৪০; 41) ৪১; 42) ৪২; 43) ৪৩; 44) ৪৪; 45) ৪৫; 46) ৪৬; 47) ৪৭; 48) ৪৮; 49) ৪৯; 50) ৫০

Add an Alphabetic Counter to a List
In this example, we add a lowercase alphabetic numbering to a list of shades of gray. THe alphabetic numbering is also known as symbolic numbering and in this counting system 1 is "a", 2 is "b", 3 is "c", …, 26 is "z", 27 is "aa", 28 is "ab", …, 52 is "az", 53 is "ba", and so on. We split the input colors by the regular expression "/;?\s+/" via the "Split Items by a Regexp" mode. We put the alphabet in square brackets and display the list items in a column.

Add a Reverse Numbering
This example adds reverse numbering to a list of people's names. We use the uppercase Roman numerals for the counter and enable a custom numbering format for them via the pattern "#%n: ", where "%n" is each Roman numeral and "#" is the hash/pound symbol.
