Line Numbering

Line numbering is an essential tool for developers, editors, and writers who need to reference specific parts of a text or code snippet. Whether you are preparing a manuscript, debugging code, or organizing a list, our Line Numbering tool provides a fast and customizable way to prefix every line with a sequence of numbers. Simply paste your text into the input field and customize the sequence by choosing your starting number and increment step. You can style the output with various separators like periods, colons, or vertical bars, and toggle zero-padding to ensure all line numbers have a consistent width. The tool also includes a skip toggle to keep blank lines clean by only numbering lines with content. Once your text is ready, you can instantly copy it to your clipboard or download it as a .txt file.
