About the Remove Duplicate Lines
Paste a list and keep only unique lines. Options let you ignore upper and lower case, trim spaces, remove empty lines and sort the output, so it works for email lists, keywords and log lines.
How to use it
- Paste your list with one item per line.
- Choose options such as ignoring case or sorting.
- Copy the unique lines and check how many duplicates were removed.
Frequently asked questions
- Which copy of a duplicate is kept?
- The first occurrence stays and later copies are removed, unless you choose to sort.
- Is there a size limit?
- Only your browser’s memory. Lists of tens of thousands of lines work comfortably.
