Line Number Adder
Add line numbers to text with configurable start number, padding width, and separator character.
How to Use Line Number Adder
The Line Number Adder prepends line numbers to each line of your text. Configure the starting number (default 1), choose a separator between the number and text (default colon-space), and select padding width (auto-detect, none, or fixed 2-4 digits). This is useful for referencing specific lines in code reviews, preparing numbered lists from plain text, adding line references to documentation, or formatting text for presentations. Handles any amount of text and preserves the original content exactly as entered.
