How to Use the Text Line Number Adder
The Text Line Number Adder automatically prefixes every line of a block of text with a sequential number. Paste in your text, and it splits the content by line breaks and adds a number and separator to the start of each line. You can set a custom starting number if you don't want the list to begin at 1, and the digit padding option can add leading zeros (like 01 or 001) so every number lines up neatly regardless of length.
Choose from a period, closing parenthesis, colon, or pipe as the separator to match code listings, song lyrics, or a numbered set of instructions. It's especially handy for adding line numbers to a code snippet for a tutorial, numbering verses in lyrics, or tidying up a long list into a clean, ordered format. The result appears as ready-to-copy text, and everything is processed right in your browser — nothing you enter is ever sent to a server.
