How are numbers inside text handled?

Naturally. item2 sorts before item10, rather than after it as a plain text sort would produce. This is what you want for filenames, version strings and numbered lists.

Does sorting also remove duplicates?

No, sorting keeps every line. To remove repeats, run the list through the remove duplicate lines tool either before or after sorting.

Do leading spaces change where a line ends up?

Yes. A leading space or tab sorts ahead of any letter, digit or punctuation mark, so with A → Z an indented line comes before every line that starts with one of those, and with Z → A after it. Tick "Trim each line" to remove leading and trailing spaces and tabs before sorting; the result then shows the trimmed lines.

Sort Lines Alphabetically — free, and it runs in your browser

Sort a list of lines A–Z, Z–A, or by length.

Ten lines or a hundred thousand, with no size limit and no pagination.
Natural ordering, so item 2 comes before item 10 rather than after it.
Blank lines and stray whitespace are handled predictably instead of scattering.

Sort Lines Alphabetically in three steps

Paste your lines
Any list, one entry per line. Nothing is sent anywhere.
Choose the order
Alphabetical in either direction, or by length when you are looking for the outliers.
Copy the sorted list
Straight to the clipboard, ready to paste back where it came from.

Why use Sort Lines Alphabetically

Natural, human ordering
Numbers inside strings sort by value, so "item 2" precedes "item 10". Plain string comparison puts them the other way round, which reads as broken.
Handles real-world sizes
Large documents are processed in one pass without pagination or a cut-off, so you are not left wondering which half of the input arrived.
Your text stays in the page
What you paste is not transmitted or stored, so an API response full of customer records, a token or an internal query never leaves your machine.

Frequently asked questions

Because this sorts the way a person would, not the way a computer stores letters. JavaScript's default sort compares character codes, and every capital letter has a lower code than every lowercase letter — so it puts Zebra before apple. This tool uses locale-aware comparison instead.

Sorting a list the way people expect

Alphabetical sorting looks trivial and is not. The default sort in most programming languages compares UTF-16 code units, which means every capitalised entry lands before every lowercase one: ["banana", "Apple"] sorts to ["Apple", "banana"] for the wrong reason, and ["apple", "Banana"] sorts to ["Banana", "apple"] which is plainly wrong.

This tool compares using locale rules, so case is ignored for ordering purposes and accented letters sort next to their base letter rather than after Z. Digits inside text are compared numerically, so item2 precedes item10.

The other sort modes

Sorting by length is useful for finding outliers — the one malformed row in a column of IDs is usually the longest or shortest. Reverse order does not sort at all; it simply flips the list you already have, which is what you want when the input was already in a meaningful order.

Pair this with remove duplicate lines to get a clean, ordered, unique list.
