With this online tool you can easily number lines. On each line number, a text can be prefixed or appended. As another setting option you can adjust the starting value arbitrarily. By default, the numbering starts at one. Another practical feature is the option to set the number of leading zeros. That way you can ensure that all line numbers have the same number of digits.

Instructions for using the tool

First, enter the lines to number into the input field. Next, you specify the initial value of the numbering as well as a possible prefix and suffix. Optionally, you can add leading zeros to each number. Finally, simply click on the button labeled "Numbering lines" to perform the numbering.
