What Is a List Reverser?

With this utility, you can reverse the order of items in a list. The utility first splits the input list into individual items and then iterates through them from the last item to the first item, printing each item to the output during the iteration. The input list may contain anything that can be represented as textual data, which includes digits, numbers, strings, words, sentences, etc. The input item separator can also be a regular expression. For example, the regex /[;,]/ will allow you to use items that are either comma- or semicolon-separated. The input and output list items delimiters can be customized in the options. By default, both input and output lists are comma-separated. Listabulous!

Reverse Examples

Reverse a List of Digits

In this example, we load a list of digits in the input. The digits are separated by a mix of dot, comma, and semicolon characters, so we use the regular expression split mode and enter a regular expression that matches all these characters as the input item separator. In the output, we get a reversed list of digits that all use the semicolon as a separator.

Input
2, 9, 6; 3; 7. 4. 4. 2, 1; 4, 8. 4; 4. 8, 2, 5; 1; 7; 7. 0
2, 9, 6; 3; 7. 4. 4. 2, 1; 4, 8. 4; 4. 8, 2, 5; 1; 7; 7. 0
Output
0; 7; 7; 1; 5; 2; 8; 4; 4; 8; 4; 1; 2; 4; 4; 7; 3; 6; 9; 2
0; 7; 7; 1; 5; 2; 8; 4; 4; 8; 4; 1; 2; 4; 4; 7; 3; 6; 9; 2

Reverse a Column of Words

This example reverses a column of twenty three-syllable nouns and prints all the words from the bottom to top. To separate the list items, it uses the \n character as input item separator, which means that each item is on its own line.

Input

Reverse a Random List

In this example, the list elements are random cities, zip codes, and weather conditions. To reverse list elements, we first need to identify them and separate them apart. The input list incorrectly uses the dash symbol to separate the elements but the output list fixes this and uses commas.

Input
Hamburg-21334-Dhaka-Sunny-Managua-Rainy-Chongqing-95123-Oakland
Hamburg-21334-Dhaka-Sunny-Managua-Rainy-Chongqing-95123-Oakland
Output
Oakland, 95123, Chongqing, Rainy, Managua, Sunny, Dhaka, 21334, Hamburg
