I once inherited a 4,000-line email list with duplicates, mixed case, and blank lines, and a deadline. Manual cleaning would have taken the afternoon; sort-and-dedupe took eleven seconds. Text-list janitorial work is pure toil: necessary, mindless, and exactly what tools are for.
Paste any line-based list to sort alphabetically or numerically, strip duplicates, remove blanks, and optionally shuffle or reverse. Email lists, keyword sets, log excerpts, survey responses, inventory SKUs, if it’s one-item-per-line, it cleans in one pass. Case-insensitive dedupe catches the ‘Apple’/’apple’ doubles naive tools miss.
Try it now: open the free tool, runs 100% in your browser.
Data-hygiene notes: sort before deduping mentally (sorted lists make remaining near-duplicates visible, ‘St.’ vs ‘Street’ won’t auto-merge, and you should eyeball those), trim whitespace first (trailing spaces create phantom uniques), and keep the original file untouched, clean into a new copy so nothing is unrecoverable. For recurring lists, graduate to a spreadsheet’s Remove Duplicates or a five-line script; the web tool is for the one-offs that don’t deserve infrastructure.
Bottom line: paste, sort, dedupe, eyeball near-misses, never destroy the original.
