This is a super simple browser-based application that changes the length of a list and adds or removes items to/from it to get the exact number of items in the final list. You can load any list in the input, separate its items by any character (or a regular expression), and set the required number of items in the options. You can specify one or more items to add to the list (if it's too short) and specify the side where these items will be added. You can also remove items from either side to make it shorter.

This online utility changes list's size by either adding new items to it (if the size is increased) or removing existing items from it (if the size is decreased). In the options, there's a field where you can set the total number of items that the list should have. For example, if you have a list with 25 items, you can extend it to have 100 items, or if you have a list with 77 items, then you can contract it to have only 50 items. You can also start with an empty list and create a list with exactly 200 items in it (or any other number). Regardless of the length of the initial input list, you'll get a new list with exactly the specified number of items in the output. To make the program correctly identify items in the list and calculate the initial number of items, when you load your list into the input field, you have to indicate what separator is used between its items. It can be a simple character (which is specified in the character delimiter mode) or it can be several changing characters (which are specified in the regular expression mode). If the current item count is greater than the desired list length, then the program will truncate the list to the desired length. If the current number of items is less than the desired length of the list, then the program will pad the list with items specified in the new-items option. You can extend the list with a single item that's duplicated multiple times or enter several items (one per line) and they will be cycled through and repeatedly appended to the list. You can add items to the list both on the left side (beginning of the list) and on the right side (end of the list). Technically speaking, when the items are added at the beginning of the list, this operation is called left padding, and when the items are added at the end of the list, the operation is called right padding. Also, you can remove empty items and specify the connection symbol for the items in the output. Listabulous!
In this example, the owner of a furniture store decided to go through the inventory and label all boxes of goods. She created a column list of labels for the first 9 boxes but as the remaining 3 boxes were sealed, she wasn't quite sure what was inside of them. To create a printable list of labels for all 12 boxes, she set the length of the new list to 12 items and filled the blank labels with the text "Unknown product".
In this example, we are preparing a playlist for Christmas. As we also have planned to watch a film in the evening, we decided to shorten the playlist to just six songs. To make the list of songs a fixed length, we paste it in the input, split the Christmas songs by a regexp "/[;,]\s*/" (matches commas and semicolons), and set the length of the output list to 6 items. Job done!
In this example, we're changing the length of a list of phone numbers. There are only 8 phone numbers in the loaded list but for our purpose, we need it to have 15 items. We separate the input list items with a newline character and set the desired length of the output list to 15 items. To fill the list, we enter three random phone numbers in the new items list and repeatedly add them to the beginning of the list, until the list grows to 15 items.
