This is a super simple browser-based application that duplicates a list and makes multiple copies of its items. When you duplicate the input list, all its items are copied and appended at the end of the original list. For example, you can create two copies of a list, three copies of a list, or even a fractional amount of copies of the original input list, such as 5.5 copies or 7.75 copies. It works with any list format as you can adjust the input item separator and also you create a new output list format by setting a new output list item separator.

This online tool creates copies of items of textual, symbolic, and numeric lists. Once you load a list in the input, you'll instantly get as many copies of the same list as you requested in the output. The number of copies is defined in the options and can be either an integer or a fraction. If the quantity is an integer, then you will get exactly that number of lists with all the items in the output. For example, if the input list is "a, b, c", and the copy count is 3, then you will get "a, b, c, a, b, c, a, b, c" in the output. If the quantity is a fraction, then you will get the number of copies equal to the integer part of the quantity plus the sliced part of the list with the number of items equal to the fractional part of the quantity. For example, if the input list is "w, x, y, z", and the copy count is 2.5, then the output list will be two copies of "w, x, y, z" plus a half which is "w, x", so the final output list will be "w, x, y, z, w, x, y z, w, x". By default, the program uses the concatenation mode. This means that duplicated list items will appear at the end of the original list. There is also the interweave mode. In this mode, each duplicated item will appear next to the original item. For example, if you interweave the list "a, b, c" twice, then it will become "a, a, b, b, c, c". Also, you can add a reverse copy to the list using the "Reverse Duplication" mode. In this case, the list "a, b, c" will become "a, b, c, c, b, a" in concatenation mode and it will become "a, c, b, b, c, a" in interweave mode. The interweave mode is also known as the zip mode or the zip operation as it acts as a zipper. To make the tool correctly recognize items in a list, you need to specify the separator that goes between the items. If it's the same character (such as a comma or a space) or string (such as a pattern), use the "Symbol Delimiter" split mode. If it's a changing/dynamic character or string (such as a mix of various symbols), use the "RegExp Delimiter" split mode. After duplicating the list, the items of the new list will be concatenated via the output list item separator symbol that you can also change in the options. Listabulous!

In this example, we duplicate a price list from a clothing store. We specify the input item delimiter to be the newline symbol, create two copies of the list, and join them also with a newline symbol.
In this example, we make 3.33 (three and one-third) copies of the Greek Gods list. As the elements of the input list are separated by commas, spaces, tabs, and newlines, we use the regex "/,\s+|\n+/g" to match all possible separators. As a result, we get three whole lists and another 33% of the original list.
In this example, we create 10 copies of the input list. As we set "\n" to the separator character in the options, the utility assumes that each line of the input is a single list item. In this case, the list has just one item that's a full cubic equation. To duplicate it ten times, we enter "10" in the copies option and also set the output list separator to a new line character. This way, the output list has 10 lines with the same cubic equation on each line.
In this example, we duplicate the items and create a palindromic list of color gradients. We activate the "Reverse Duplication" option, set the number of copies to 2, and get a symmetrical list that goes from red to yellow and back to red. The arrow symbol serves as the input and output separator of items.
In this example, we demonstrate the interweave method for duplicating list items. We take a list of lowercase vowels of the English alphabet and create two interwoven copies. As a result, each letter is copied next to itself and we get two copies of each letter. Also, if you're familiar with functional programming then you'll recognize that interweaving is the same as zipping.
