Line numbers are essential for referencing specific parts of text, code, or documentation. This tool automatically adds sequential line numbers to each line of your text, making it easy to discuss or reference specific lines.
The tool also includes a "Remove Line Numbers" mode that strips existing line numbers from text. This is useful when you've copied numbered text and want to clean it up, or when you need to reformat content that already has numbering.
