This is a super simple browser-based application that finds the length of a list. It can count the number of all list items, only the unique items, or only the duplicate items. It can also include or exclude empty items and items consisting of only whitespace characters. Created by list geeks from team Browserling.

With this utility, you can get the total count of items in a list. By default, it counts the number of all items, including empty items and invisible items (invisible items are those that contain only whitespaces). You can also adjust the counting mode and count just the unique items or just the duplicate items. Before the program can count the items, it has to parse the input data and find the list items. To do that, you need to tell the program how the items are separated and the separator can be configured in the options. By default, the program uses the split-by-character mode. It's suitable for cases when the delimiter matches a constant character or a group of constant characters. For example, in the list "1 2 3", the delimiter is the space character and in the list "1/\2/\3", the delimiter is a slash and a backslash symbol "/\". In the case when the separator changes between items, you can use the split-by-regex mode. For example, the list "1, 2; 3" uses a comma and a semicolon to separate items and the regular expression /[, ;]+/ will work in this case. If you don't want to count empty items, then deselect the "Count Empty Items" option. Similarly, to avoid counting items made out of just spaces, tabs, and newlines, deselect the "Count Invisible Items" option. Listabulous!

In this example, we count elements in a list and calculate how many hexadecimal numbers there are in this list. Since the input list uses the same symbol as a delimiter for all items, we use the symbol-delimiter match mode and enter the comma symbol in the option below. With these options, we quickly find the total number of hexadecimal values in the list, including blank and whitespace items.
In this example, the input list of month names is neatly formatted and uses several different separator characters, such as tabs, spaces, and newlines to evenly align all the months in nice columns. To properly separate the months in this multi-column list, we select the mode where a regular expression matches all separator characters and enter /\s+/ in the regular expression field. As some months repeat more than once, we choose to count only the unique items and get the value 12 in the output, which confirms that no months were missed or mistyped.
In this example, we're using the first three English letters to demonstrate how counting duplicate items works. There are multiple ways to count duplicate items and we're using the formula "total = unique + duplicate" to find the duplicate items count. If we rearrange the terms, we get "duplicate = total - unique". The first three letters in the example are unique and all the others are their copies. Therefore, the counting starts after the third items and the program finds that there are 6 duplicate copies.
