About this tool

Appends a specified string of characters to the beginning of every line within an input block of plain text. Users simply paste their multi-line content into the designated field, enter the desired prefix text, and the tool processes the data instantly. The output displays the original lines with the chosen string prepended to each one, maintaining the structural integrity of the rest of the text. Individuals needing to format lists or data sets that require uniform labeling can utilize this utility. It is particularly helpful for programmers creating sample code snippets, writers formatting structured outlines, or anyone preparing plain text reports that need a consistent identifier on every line item. This allows users to quickly standardize and organize bulk text content without manual editing.
