This alphabetizer uses your page language's native collation rules instead of comparing raw character codes. It also applies natural number order, so Project 2 appears before Project 10. Your original input stays untouched while options update the sorted copy on the right.

How do I sort lines alphabetically?
Paste a list with one item per line and this tool sorts the lines alphabetically as you type. Choose A-Z or Z-A order, make case significant when needed, and optionally trim spaces or remove blanks and duplicates. Sorting happens in your browser, so the text is never uploaded.
How to use
- 1Paste the list. Enter one item per line in the left box. Windows, Mac and Unix line endings are recognized.
- 2Choose the order. Select A-Z or Z-A, then turn on case sensitivity or cleanup options if your list needs them.
- 3Copy the sorted lines. Review the live result on the right and use Copy to place the finished list on your clipboard.
Who it's for
- Writers and researchers alphabetizing references, reading lists, names or interview notes before sharing them.
- Developers sorting configuration entries, filenames, package lists or log labels to make diffs easier to scan.
- Marketing and operations teams cleaning keyword lists, product names, tags and pasted spreadsheet columns.
- Students and teachers arranging vocabulary, attendance lists and source titles in a consistent order.
FAQ
Is my list uploaded anywhere?
No. The list is sorted locally by JavaScript in your browser and is never sent to a server. You can use the tool for unpublished notes, internal labels, private filenames and other text you would rather not upload.
Is this alphabetical line sorter free?
Yes. It is free to use, needs no account and has no built-in usage limit. Paste your lines, change the options as often as you like, and copy the result without installing an app or browser extension.
How many lines can I sort?
There is no fixed line limit. Sorting uses your device's memory and processor, so practical capacity depends on the browser and hardware. Ordinary lists and large pasted text columns finish instantly; extremely large files are better handled by a desktop or command-line tool.
Can I sort from Z to A?
Yes. Choose Z-A above the input to reverse the alphabetical comparison. This is a true descending sort, not merely a visual reversal, so lines that compare as equal keep their original relative order.
Does uppercase come before lowercase?
Case is ignored by default while accents remain significant. Turn on Case sensitive when capitalization should affect ordering. Exact uppercase-versus-lowercase placement follows the collation data supplied by your browser for the page language.
Does it sort numbers correctly?
Yes. Natural numeric comparison is always enabled, which means Item 2 comes before Item 10. A basic character-code sort would place Item 10 first because it compares the first digit, but this tool treats embedded digit runs as numbers.
Can it remove duplicate or blank lines while sorting?
Yes. Turn on Remove duplicates to keep one copy of equal lines, or Remove empty lines to drop blank and whitespace-only entries. Trim whitespace first when leading or trailing spaces should not make otherwise identical lines different.
