About the Add Line Prefixes Tool
The Add Line Prefixes Tool lets you quickly prepend custom prefixes to every line of your text. Whether you're working with code, logs, data entries, or structured text, this tool ensures consistency and saves time by automating prefix additions.
Manually typing the same prefix at the start of dozens or hundreds of lines is tedious and easy to miss on at least one line. This tool splits your text on line breaks, prepends your chosen prefix to every line, and rejoins them instantly — useful for adding paths, bullet markers, indentation, or any repeated text element.
