Frequently Asked Questions
How do I split a comma-separated list into lines?
Select the "Split to Lines" mode and enter a comma in the delimiter field. Paste your comma-separated values into the input, and each item will appear on its own line in the output.
Can I remove duplicate items from a list?
Yes. Select the "Remove Duplicates" mode and paste your list with one item per line. The tool will keep only unique items while preserving the order of first occurrence.
How does the sorting work?
The sort mode arranges lines alphabetically using locale-aware comparison. You can switch between ascending (A-Z) and descending (Z-A) order with the toggle buttons.
Can I add custom numbering to my list?
Yes. Use the "Number Items" mode and customize the prefix and suffix fields. For example, set the suffix to ") " to get numbering like "1) Item" or leave the default ". " for "1. Item".
