Line Sorter & Deduplicator
Alphabetize lists, remove duplicate entries, strip empty lines, and reverse ordering in real-time.
Natural Alphabetical Sorting
Uses internationalized string collation (localeCompare) so alphanumeric items like "Item 2" naturally precede "Item 10".
Deduplication
Instantly scrubs repeated entries from database extracts, keyword lists, or email registries while preserving clean line breaks.
Confidential & Offline
Your data never leaves your browser. Safe for proprietary customer lists, subscriber emails, and internal inventory spreadsheets.
Frequently Asked Questions
How do I sort a list alphabetically?▼
Paste one item per line and press A to Z (or Z to A). Sorting uses your browser's language rules, so accented letters sort sensibly and numbers inside text are compared as numbers.
How do I remove duplicate lines?▼
Tick the option to remove duplicates. Matching is not case sensitive unless you turn on the case-sensitive option.
Can I sort by line length?▼
Yes. There are buttons for shortest first and longest first, and a button to reverse the current order.
Can it clean up blank lines and extra spaces?▼
Yes. You can trim spaces from each line and strip empty lines before sorting.
How big a list can it handle?▼
Lists of hundreds of thousands of lines work, because sorting happens on your own device. Pastes over 200,000 characters are processed after a short pause while you type.
Is my data sent to a server?▼
No. The sorter runs entirely in your browser, so nothing you enter is uploaded, stored or tracked. Once the page has loaded it keeps working without a connection.
