Working with lists is a constant task — sorting names, numbering steps, removing duplicate entries, or converting a column into a comma-separated string. Doing it by hand is slow and error-prone. Our free list formatter handles every common list operation in one click, right in your browser.
What the List Formatter Does
The tool takes any list — one item per line — and transforms it in whatever way you need:
- Bullet ↔ numbered — convert lines into a bulleted list, or into a numbered 1, 2, 3 list.
- Sort A→Z or Z→A — arrange items alphabetically in either direction.
- Remove duplicates — keep only the first occurrence of each item.
- Reverse order — flip the sequence of the whole list.
- Trim items — strip leading and trailing spaces from every line.
- Remove markers — strip existing bullets or numbers.
- List ↔ CSV — join items into a comma-separated line, or split a CSV back into a list.
How to Format a List Online
- Paste your list into the input box, one item per line.
- Click an operation — sort, number, deduplicate, convert to CSV, and so on.
- Copy the formatted result with one click.
You can chain operations — for example, remove duplicates, then sort, then number — to get exactly the list you want.
