Add List Item Counter

What Is a List Item Counter?

The Add List Item Counter tool lets you add sequential numbers, counters, or enumerations to each item in a list. You can choose from several predefined formats or create your own custom format with a prefix and suffix. This is useful for creating numbered lists, inventories, to-do lists, and any ordered collection of items.

Split your input list by a character or regular expression, choose a counter format and starting number, optionally configure a custom prefix/suffix, and instantly get a numbered list with your chosen output separator.

How to Add a List Item Counter

1. Paste or type your list into the Input List text area.
2. Choose a Separator Mode — use Literal for a fixed character or Regex for a pattern.
3. Enter the Input Separator that currently divides your items.
4. Set the Starting Number and choose a Counter Format.
5. If using Custom Format, enter your prefix and suffix.
6. Set the Output Separator and view the numbered list instantly.
