What is Line Number Adder?

Line Number Adder prepends sequential line numbers to every line of your text. Handy for referencing specific lines in code reviews, documentation, or when sharing text snippets where line references matter.

How to use

1. Paste your text — code, logs, or any multi-line content — into the input area.
2. Choose your numbering format: separator style (dot, colon, tab, pipe), starting number, and padding options.
3. Copy the numbered output or download it as a text file for sharing in emails, reports, or code reviews.

Result

You need to reference specific lines from a server log during an incident review. Add line numbers so your team can quickly jump to 'line 47' or 'lines 112-118' in the discussion.
