Need to add line numbers to your text? Whether you're preparing code snippets for documentation, numbering lines in a script, or organizing poetry, here's how it works:
Line numbers might seem like a small detail, but they're incredibly useful in many situations. When you're sharing code snippets, line numbers help others reference specific lines easily. In documentation, line numbers make it simple to point out exact locations. For scripts and screenplays, line numbers are essential for coordination. And for poetry or lyrics, line numbers help with analysis and discussion. A line numberer tool saves you from manually adding numbers, which is tedious and error-prone, especially with long texts.
This tool automatically adds line numbers to your text. You can choose different numbering formats (like '1.', '1)', or just numbers), set the starting number, and the tool will number each line of your text instantly. Perfect for code snippets, scripts, poetry, or any text that needs line numbering.
The tool analyzes your text line by line using JavaScript that runs right in your browser. As soon as you paste or type text, it splits the text into lines and adds numbers to each line according to your chosen format. Everything happens instantly on your device - your text never leaves your browser, ensuring complete privacy.
