What This Tool Does
This line sorter and deduplicator takes any list of lines, a list of URLs, names, tags, log entries, anything separated by line breaks, and sorts, cleans, and deduplicates it live as you type. Four sort modes cover the common cases: A-Z, Z-A, a literal reverse of your input order, and a random shuffle. Four independent toggles handle cleanup: remove duplicate lines, compare case-insensitively, trim whitespace from each line, and strip out blank lines entirely. All four toggles and the current sort mode work together in any combination.
How to Sort and Clean Up a List of Lines
Paste your lines into the left panel, pick a sort mode, and toggle whichever cleanup options you need, the sorted, cleaned result appears in the right panel instantly with no button to press. The status bar reports exactly how many duplicate lines and how many blank lines were removed by your current settings, so you always know what changed between your input and the output.
Reverse vs Z-A Sort (the Real Distinction)
Reverse and Z-A sort are easy to confuse but do genuinely different things. Reverse literally flips your input's line order, whatever was last becomes first, with no regard for alphabetical order at all. Z-A sort ignores your input's original order completely and performs a true descending alphabetical sort. The two only produce an identical result if your input happened to already be sorted A-Z, otherwise they diverge, and picking the wrong one is a common mistake this distinction is worth understanding before you rely on either.
Common Uses for a Line Sorter
Deduplicating a list of email addresses or URLs before importing it somewhere, alphabetizing a bibliography, credits list, or set of names, prepping a raw list before feeding it into a CSV or config file, and randomizing a list order for fair sampling or randomized assignment are all common reasons to reach for a text line sorter free tool like this one instead of sorting a list by hand.
A Free Way to Sort or Shuffle a List
Use it to sort lines alphabetically as a sort text lines online tool, an alphabetize list online utility, a way to sort list a to z or reverse lines order, and a shuffle lines online option whenever you need a randomized order instead.
