list item deleter

world's simplest list tool

This is a super simple browser-based application that deletes certain items from a list. You can load any list in the input and remove all items that match a specific pattern. The specific pattern can be a short string, a bunch of symbols in any order, or a regexp. You can use multi-format lists (such as comma-delimited lists or todo lists) and adjust to their format using the list item delimiter options. Created by list geeks from team Browserling.

What is a list item deleter?

This online program removes unwanted items from a list. It offers several different item removal modes. In particular, the first mode allows you to get rid of items that contain a specific text pattern. For example, if you select this mode and enter the pattern "sun", then the program will remove all items that contain the word "sun". The second deletion mode allows you to delete items based on their symbolic composition. For example, you can specify the symbols "abct", which means that the removed items consist of one or more of these symbols. In this case, the items "cat", "bat", "cab", and "catb" will be removed (and all other combinations made out of these four letter, such as "a", "b", "c", "t", "ab", "bt", etc). The third mode removes those items that are accepted by a regular expression. For example, you can remove all numeric items via a regexp "/^\d+$/" or all items that end with a question mark via a regexp "/.+\?$/". To use the program, you also need to indicate the separator character that's used for its items. If it is a single separator or a multi-character separator, use the "Symbol Delimiter" option. For example, if you have a hash-symbol separated list, then enter the "#" character in the text field. The same applies to comma-separated or semicolon-separated lists. If you have a vertical to-do list, then enter the "\n" in this field, which indicates there is one item per line. If your list uses several different characters between the items, use the "Regexp Delimiter" option. For an updated list in the output, you can use any new separator character. Additionally, you can use the "Skip Empty Items" option to delete all items that contain nothing (that either have no length or contain just the spaces). And finally, there's also a neat preview option that lets you output the deleted items to the screen. It's very useful when you need to make sure the right items are getting deleted. Listabulous!


List item deleter examples

Tourist Attractions in the USA

In this example, we found a list of the most popular American tourist attractions. We're interested in almost all of these, except for the parks. To remove all parks from the list, we split its items by the newline character (as each attraction is listed on a new line), select the substring deletion mode, and enter the substring "Park" in the matching option. As a result, all items with the word "Park" are now removed and we don't have to manually remove them anymore.

Delete Afternoon Clock Times

This example removes the afternoon times (P.M. times) from a clock times list. The list consists of two tab-separated columns. To correctly separate all list items, we use the regular expression delimiting mode with the regex /\t|\n/. We switch to the "Match All Symbols" option and indicate that the items to be deleted must contain only numbers, a colon, a space, and the letters "pm". As a result, we get a cleaned list with just the A.M. times. The resulting list items are separated by a comma.

Delete Items from a Todo List

In this example, we want to remove two specific items from a todo list. We select the delete mode that uses a regular expression and specify the regex /^(cook food|check mail)$/. This regular expression instructs the program to delete only the items "cook food" and item "check mail", and nothing else.
