Example

Sort and deduplicate a copied list

Natural sorting keeps item2 before item10, and duplicate removal can treat Apple and apple as the same value.

Input


                        banana
Apple
apple
item10
item2

  carrot

Output


                        Apple
banana
carrot
item2
item10

Practical Notes

Use natural numeric sorting when your list contains numbered items such as file2, file10, or step12.
Use ignore case when duplicate lines should be treated the same even if capitalization differs.
Keep blank lines only when they carry structure. For most lists, removing blank lines makes sorting easier to review.

How to Use

1. Paste a list of lines into the input box.
2. Choose whether to trim lines, remove blank lines, ignore case, use natural numeric sorting, or remove duplicates.
3. Click Sort A-Z or Sort Z-A to generate the cleaned output.
4. Copy the sorted result when it is ready.

Frequently Asked Questions

What is a line sorter?

A line sorter rearranges each line of a text block into alphabetical or reverse alphabetical order. It is useful for lists, keywords, URLs, names, and one-column exports.

Can this tool remove duplicate lines?

Yes. Enable Remove Duplicates before sorting. You can also enable Ignore Case when Apple and apple should count as duplicates.

What is natural numeric sorting?

Natural sorting compares numbers inside text as numbers, so item2 comes before item10. Basic alphabetical sorting may place item10 before item2.

Is my pasted list uploaded?

No. Sorting, trimming, and deduplication happen locally in your browser after the page loads. Your text is not uploaded to QuickToolFlow.
