Paste your text into the left box, select whether you want to skip numbering on empty lines, and click "Add Line Numbers". The tool will automatically prepend sequential numbers to each line of your text.
Example
Three lines of text become "1. First line", "2. Second line", "3. Third line" — ready to paste into a numbered reference list.
Common Use Cases
- Numbering code snippets or configuration files for reference.
- Creating a numbered list from plain text quickly.
FAQs
Is this the same as a line number calculator?
Yes — people search for a "line number calculator" when they want sequential numbers added to a list or document; this tool does exactly that, working out and inserting the correct number for every line automatically.
How do I add line numbers to my text?
Paste your text into the box, choose your numbering options (skip empty lines, dot or no dot after the number), and click "Add Line Numbers" — every line gets numbered instantly.
Can I number only non-empty lines?
Yes — enable "skip empty lines" and blank lines are left as-is without incrementing the counter.
