Deduplicate text lists, remove empty lines, trim whitespace, and sort lines alphabetically.
Clean list data from CSV files, database queries, or email lists in seconds. Remove identical entries, trim extraneous spaces, strip blank lines, and sort entries alphabetically without installing software or writing scripts.
The tool splits your input by newlines and tracks unique items in an in-memory hash set. You can toggle case-sensitivity to treat "Apple" and "apple" as the same or different, and enable trimming to ignore leading and trailing whitespace.
Because deduplication runs 100% locally in your browser using JavaScript's native Set data structure, you can comfortably process tens of thousands of lines in milliseconds without browser lag or freezing.
No. All list processing, whitespace trimming, and sorting happen client-side in your browser. No list content, emails, or IDs ever leave your machine.
