A line sorter is a free online tool that arranges your text lines in alphabetical order, A to Z or Z to A. It offers case-sensitive sorting, natural numeric sorting so "item2" comes before "item10", and an option to drop empty lines.

How do I sort lines alphabetically online?
Short answer: Paste your lines into the box above, one item per line, and the sorted result appears instantly. Choose ascending for A to Z or descending for Z to A. The output box holds the sorted list with a one-click copy button, so moving a cleaned list into a spreadsheet or document takes seconds.
For best results, put each item on its own line before sorting. If your data is comma-separated, use Find & Replace to turn commas into line breaks first. Pair this tool with Remove Duplicates to clean a list and sort it in two quick steps.
What is natural numeric sorting?
Short answer: Natural numeric sorting treats embedded numbers by their value, so 'item2' sorts before 'item10'. Plain alphabetical sorting compares character by character, which wrongly puts 'item10' before 'item2' because '1' comes before '2'. Leave the natural sort toggle on whenever your lines contain version numbers, episode numbers or numbered items.
This matches how file managers sort filenames on modern operating systems. If your lines are purely alphabetic with no digits, natural and plain sorting give identical results, so the toggle only matters for numbered content.
Does sorting distinguish uppercase from lowercase?
Short answer: Only if you enable case-sensitive sort. With it off, which is the default, 'Apple' and 'apple' are treated as equal and their relative order follows the sort stably. With it on, all uppercase letters sort before lowercase ones in most locales, so 'Zebra' comes before 'apple'.
For everyday lists like names or keywords, leave case-sensitive off for the most intuitive A to Z order. Turn it on for code or data where exact character ordering matters.
Frequently asked questions
Is this line sorter free?
Yes, free and unlimited. Sort as many lists as you like with no account and no limits.
Can I sort Z to A?
Yes. Choose the Descending option to sort from Z to A, or largest to smallest for numbered lines.
Will it remove duplicate lines?
No, sorting only reorders. Use the Remove Duplicates tool first if you want a sorted list of unique lines.
How does it handle numbers?
With natural numeric sort on (the default), numbers inside text sort by value: item2 before item10. Turn it off for strict character-by-character ordering.
Is my text uploaded anywhere?
No. Sorting runs entirely in your browser, so your lists stay private.
