Add Line Numbers

Line numbering is an online tool that adds sequential numbers to each line of your text, making it easy to reference specific lines. Whether you're a developer creating numbered code snippets, a writer preparing numbered lists, or someone organizing content, our line numbering tool handles all your sequential numbering needs effortlessly.

This tool adds customizable line numbers (starting number, separator) to the beginning of each line. Simply paste your text, configure numbering options, and get numbered results instantly.

Line numbering is essential for code sharing when you need to reference specific lines in discussions, code reviews, or documentation. Developers frequently add line numbers to code snippets for tutorials, stack overflow posts, or technical documentation where line-specific references are necessary.

Writers and editors use line numbering for poetry, scripts, or legal documents where line-by-line reference is required. Teachers benefit from numbering when creating worksheets, practice problems, or assignments where students need to reference specific line numbers.

The tool saves time by automatically numbering all lines with consistent formatting and sequential order. It's particularly useful when working with long texts where manual numbering would be error-prone and time-consuming.
