List Item Replacer

World's Simplest List Tool

This is a super simple browser-based application that replaces list items. You can change one or more items to new items or rewrite a part of an existing item with a new text fragment. You can match items for replacement using the items themselves or using a regular expression. The input list items can have any format (comma-separated, tab-separated, or vertical to-do items) and for your convenience, you can also remove empty items from the output and clear items from surrounding spaces. Created by list geeks from team Browserling.

What Is a List Item Replacer?

This online tool replaces certain list items with new items. Additionally, it can also remove parts of an item, change the order of parts of an item, and replace parts of an item with new parts. Suppose you have a list of animals and you want to replace all items containing "cat" with "kitty"; or you have a list of temperature readings and you want to replace Celsius "°C" with Fahrenheit "°F"; or you have a list of items in the format "part1-part2" and you want to swap it to "part2-part1"; or you have a list of items that start with a bullet point, such as "* item" and you want to convert it to just "item". With this program, all these operations can be easily done! First, paste your list in the input field and specify the input and output separators for the items. The input separators can be specified using a character (for example, a comma ",", a semicolon ";", or a newline "\n") or they can be specified using a regular expression (for example, all spaces "/\s+/", or a colon followed by a possible space ": ?"). The output delimiter can be specified using simple characters or a short string. Next, you'll have to choose one of two replacement modes. The first allows you to replace a specific item with a new one. For example, in this mode, you can replace all "cat"s with "kitty"s. And the second mode allows you to replace the items matching a regular expression with a new string that can use the old parts of the items in the new format. For example, if your regexp is "/°C/" that matches Celsius, then the replacement can be "°F" that will replace it with Fahrenheit. Here you can optionally use capturing groups and back-references to do the replacement. For example, to change the order of parts in an item, you'll use a regexp "/(part1)-(part2)/" and the replacement will be "$2-$1" (these are back-references). Another example is changing the numbering format of a list from "1. 2. 3." to "1) 2) 3)". There are also several quick and easy options to clear items from surrounding spaces and remove empty items. Listabulous!

Replace a Pizza Type

In this example, we are making a list of pizzas for a party. Unfortunately, when we called our favorite pizza place, they said that they don't make Pepperoni pizzas today, so we replaced it with a Hawaiian pizza. To do this, we separated the list items with a newline character and entered the names of the old and new pizzas in the "Replace Specific Items" options. Now we can forward the list to the pizza shop and they'll be able to make all pizzas for us. 😋

Change the Currency in a List

In this example, we load a list of products from a shady store which has the currency codes mixed up. To set all prices in dollars, we select the "Replace With Regex" replacement mode. We use the regular expression "/[€₴¥£]/" to match all currency symbols and change them to the dollar symbol "$". Also, we use a regular expression to separate the input items and turn the two-column list into a single-column item list using the rx "/\t|\n/".

item1 – 100€ item2 – 200€ item3 – 300₴ item4 – 400¥ item5 – 500£ item6 – 600₴ item7 – 700¥ item8 – 800¥ item9 – 900€ item10 – 1000£
item1 – 100$ item2 – 200$ item3 – 300$ item4 – 400$ item5 – 500$ item6 – 600$ item7 – 700$ item8 – 800$ item9 – 900$ item10 – 1000$

A List of Types of Honey

In this example, we emojify a list of honey types by replacing the word "Honey" in all the items with a beautiful Unicode emoji. We separate the honey types by a comma and also trim them from surrounding spaces. We activate the regular expression replacement mode and rewrite the substring "Honey" into a single character "🍯".

Clover Honey, Buckwheat Honey, Acacia Honey , Manuka Honey, Wildflower Honey , Tupelo Honey, Orange Blossom Honey , Sourwood Honey, Linden Honey, Sage Honey, Eucalyptus Honey, Avocado Honey, Blueberry Honey, Dandelion Honey, Fireweed Honey, Heather Honey , Macadamia Nut Honey, Palmetto Honey

Change Numbering in a Pre-trip Todo List

In this example, we re-number a pre-trip todo list. The original numbering is in the number-with-a-dot form but we want the numbering to be wrapped in square brackets. To do this, we select the regex-replacement mode, set the match pattern to "/(\d+)\./", and replace it with the pattern "[$1]". As a result, the counter values that are wrapped in parentheses "(\d+)" (in the regex) are saved in the special variable "$1" (called a back-reference) that is then used in the "[$1]" replacement string. With this trick, all counters are now wrapped in square brackets.

Add a Suffix to the List

In this example, we add an exclamation mark at the end of each item in a New Year's greetings list in different languages of the world. We split the items of the vertical list with the newline character "\n" and remove empty items. We use the regular expression "/$/" to match the end of the items and insert an exclamation character "!" in that place.

English: Happy New Year Bengali: Shuvo noboborsho Czech: Stastny Novy Rok Dutch: Gelukkig nieuwjaar French: Bonne anne Hebrew: Shana Tova Spanish: Feliz ao nuevo Swedish: Gott Nytt r Thai: Sawatdee Pi Mai Danish: Godt Nytr

Delete a Part of Items

In this example, we're working with a synonyms list. When we copied the file from a Mac to a PC, somehow the file format changed and all synonyms now have an "x" between the words. We want to delete this "x" and replace it with something better. To do it we match it via a regular expression /x/ and set the new replacement to " is a synonym of ".

Fast is a synonym of Speedy Slow is a synonym of Unhurried Colorful is a synonym of Vivid Delicious is a synonym of Tasty Silly is a synonym of Foolish Good is a synonym of Fine Happy is a synonym of Cheerful Huge is a synonym of Enormous
