Cleaned text
How to use
- Paste your text — a list, a log file, or any lines with repeats.
- Choose your options: case-insensitive, trim spaces, drop empty lines, or keep the last copy.
- Click Remove Duplicates, then copy the cleaned text or download it as a .txt file.
Frequently asked questions
Does it keep the original order?
Yes. Lines stay in the order they first appeared (or last appeared, if you tick keep-last). Nothing is sorted unless you ask for it elsewhere.
Is 'Apple' the same as 'apple'?
Only if you tick case-insensitive. By default the comparison is exact, so different capitalisation counts as a different line.
What counts as a duplicate line?
A line that matches an earlier line exactly, after the options you chose — trimming spaces and case are only ignored if you tick those boxes.
Is my text uploaded?
No. The whole job runs in your browser, and the text never leaves your device.
