The Power of Regular Expression: use in notepad++
This document provides an overview of using regular expressions in Notepad++ to perform find-and-replace operations on text. It demonstrates how to remove numbers from a list, swap numbers and names, and rearrange names to put the last name first followed by the first name separated by a comma. The explanations describe how regular expression syntax like character sets, wildcards, and capturing groups allow matching and rearranging text in the find-and-replace dialog box.
