TEXT CLEANUP
Remove Duplicate Lines
Paste a list and remove repeated lines instantly.
How this tool works
Repeated lines can make lists harder to scan and work with. This utility removes duplicate non-empty lines from pasted text while retaining the first occurrence, making it useful for cleaning lists, names, keywords and simple data exports.
How to use it
- Paste one item per line into the text area.
- Select Remove duplicates to trim lines, discard blank lines and keep each distinct line once.
- Optionally select Sort A–Z to sort the remaining lines alphabetically.
Example and practical tips
If a list contains “apple”, “pear”, “apple”, the cleaned list keeps “apple” and “pear” in their original first-seen order. Sorting is a separate action.
The current cleanup trims leading and trailing spaces before comparing lines, so “pear” and “ pear ” are treated as the same item. Keep a backup of your original list when whitespace or blank lines carry meaning.
Frequently asked questions
Does it remove repeated words inside a line?
No. It works line by line, not word by word.
Will it automatically sort the list?
No. Choose Sort A–Z separately if you want alphabetical order.
