World's simplest list tool

This is a super simple browser-based application that analyses a list and displays interesting information about it. You can find out the number of items in the list, the number of characters, find the longest and shortest items, get the average length of the items, calculate the number of unique and empty items, and get a detailed composition of its items.

List analyzer tool What is a list analyzer?
This online utility analyzes the given list and prints a summary of its statistics. You can display the statistics of any list that you load as the input. It can be a comma-separated, space-separated, tab-separated, or a vertical list, or any other list. To analyze the list and its items, you need to specify the separator that is placed between the items. You can specify it in the options using a symbol (comma, space, tab, etc.) or using a regular expression (for mixed separators). As soon as the items are separated, the program will immediately count them and print the total count to the output. It will also count the number of characters in the list (including and excluding separators). In addition, you can find out which items are the longest and which are the shortest and find out their lengths. The program can also calculate the average length of the items, the number of unique items in the list and check if there are any empty (whitespace) items in it. If you need to print the unique items in your list, you can use our Find Unique List Items utility. Similarly, if you need to print the duplicate items in your list, you can use our Find Duplicate List Items utility. Finally, the program can also display the character composition of the list and show which letters, numbers, ASCII, and Unicode characters are present in the list. Each block of information can be selectively printed to the output. You can control the output using checkboxes in the options and get only the information that you really need. Listabulous!
List analyzer examples Click to use
Analyze a List of Beverages
In this example, we analyze a vertical list of beverages. After separating the input items with a newline character, we quickly find that the list contains 7 items and consists of 31 symbols (excluding separators) or 37 symbols (including newline separators). We also find the longest and shortest word in the list and calculate the average length of all items.
Beer Coffee Juice Milk Tea Water Wine
List Length ----------- items in the list: 7 list length in symbols: 37 (with separators) list length in symbols: 31 (without separators) Longest Item ------------ maximum length: 6 longest item: • "Coffee" Shortest Item ------------- minimum length: 3 shortest item: • "Tea" Average Item Length ------------------- length: 4.43

Statistics about Car Brands
In this example, we find the statistics of a list of car brands. As there are different separators between the brands, we split the items using a regular expression "/[,;] ?/", which matches commas or semicolons, followed by an optional space. We display the information about the length of the list (find out the number of items and characters); print the information about unique items (the number of items if the copies are discarded); and output the information about empty items (the number of items with zero-length or consisting only of whitespace characters).
Toyota, Honda; BMW, Chevrolet; Ford, Mercedes-Benz; Jeep, Toyota; ; ; BMW, Porsche; Subaru, , Nissan; Cadillac, Ford; ; ; ; Volkswagen, Lexus; Audi, Ferrari; ; ; Volvo, , , Ford
List Length ----------- items in the list: 30 list length in symbols: 184 (with separators) list length in symbols: 126 (without separators) Unique Items ------------ total: 19 Empty Items ----------- total (zero-length): 7 total (whitespace): 3

Composition of a Constants List
In this example, we load and parse a list of math constants. We print the general information about the length of the list as well as detailed information about the composition of the list. Namely, we find out which uppercase and lowercase letters are used in the list, which digits are used in it, as well as which other ASCII and Unicode symbols are present in the mathematical constants.
Archimedes' constant π Imaginary unit i Euler's number e Pythagoras' constant √2 Theodorus' constant √3 Feigenbaum constants α and δ Apéry's constant ζ(3) Golden ratio φ Euler-Mascheroni constant γ Khinchin's constant K Glaisher-Kinkelin constant A
List Length ----------- items in the list: 11 list length in symbols: 248 (with separators) list length in symbols: 238 (without separators) List Composition ---------------- 9 uppercase letters: "AIEPTFGMK" 19 lowercase letters: "rchimedsontagyulbpk" 2 digits: "23" 5 other ASCII characters: "' ()-" 8 other Unicode characters: "π√αδéζφγ"
