What is the Line Sorter?
The Line Sorter takes a block of text and reorders it line by line. You can sort alphabetically, numerically, or by line length, reverse the order, or shuffle randomly, and clean the list at the same time by trimming whitespace, dropping blank lines, and removing duplicates.
Sorting lists by hand is tedious and error-prone, especially with mixed case, numbers, or duplicate entries. This tool handles all of that instantly: it uses a natural, case-aware comparison so that "item2" comes before "item10", and it can fold case so "Apple" and "apple" are treated as the same entry when removing duplicates.
Everything runs in your browser. Paste your list, choose how to sort and clean it, and copy the result. No account, no uploads, and it keeps working offline once the page has loaded - safe for sensitive lists that should never leave your machine.
Alphabetical and natural sorting differ in one way that matters constantly. A plain character-by-character sort puts file10 before file2, because the character 1 sorts before 2. The alphabetical mode here is natural-sort aware: it reads runs of digits as numbers, so file2 comes first, and a list of whole numbers like 2 and 10 also comes out in value order. Numeric mode still matters for decimals and negative numbers, which a natural sort reads as separate runs of digits (3.14 lands after 3.2, and -10 after -5), and it moves lines that do not start with a number to the bottom. Case is the other axis. The comparison is locale-aware rather than raw byte order, so even with ignore-case off, Apple and apple sit next to each other instead of every capitalized line sorting ahead of every lowercase one. Ignore-case removes capitalization from the comparison entirely, and entries that differ only in case keep their original order. Removing duplicates compares whole lines, so two lines differing only by trailing whitespace are not duplicates, which is why the cleaning options exist and are worth running first. Sorting happens in memory, so very large files are bounded by the tab.
