Sorting that respects the alphabet
Naive sorters order by character code, so “apple” lands after “Zebra” and “Éclair” goes to the very end. This tool sorts with the alphabet rules of the language you pick (English, Turkish, German, Spanish, Russian or Arabic), ignoring case and accents for ordering. Natural sort puts file2 before file10, numeric sort orders by the number at the start of each line, and length sort orders from shortest to longest.
Removing duplicate lines
Remove duplicates keeps the first occurrence of each line and deletes later copies without changing the order. With “case-insensitive” on, Apple and apple count as the same line. The counter shows total, unique, duplicate and empty lines, so you can see the effect before and after. Ideal for e-mail lists, keyword lists, SKUs and columns pasted from Excel.
More operations
Reverse flips the order, shuffle produces a fair random order using cryptographic randomness (good for draws), trim removes leading and trailing spaces, and prefix/suffix adds text to every non-empty line — for example to quote each item or turn a list of paths into full URLs. Everything runs locally in your browser.
Frequently asked questions
How do I remove duplicates from an Excel column?
Copy the column, paste it here, click “Remove duplicates” and paste the result back into Excel.
Does it keep the original order when removing duplicates?
Yes. Only later copies are removed; sort afterwards if you want alphabetical order.
Can I undo a step?
Yes. The Undo button reverts operations one by one.
Is there a line limit?
No fixed limit — lists with hundreds of thousands of lines are processed in your browser within seconds.
