Why use an Online Line Numbering Tool?
Adding numbers to each line of a document is a common requirement for legal professionals, coders sharing snippets, and writers organizing lists.

This utility gives you full control over the numbering format. You can choose your starting number, set a custom increment, define your own separator (like a dot or parenthesis), and even add leading zeros for consistent alignment. It’s perfect for creating structured lists or preparing text for line-referenced citations. Like all CuscusLab tools, it works entirely in your browser, keeping your data confidential and secure.
