How to use it

How to use sort and deduplicate

Sort a line-based list and remove duplicate entries with case-sensitive or case-insensitive matching.

Deduplicate a pasted email-domain list and sort it alphabetically.

  1. Enter or paste the values you want to work with.
  2. Review the result and any validation message.
  3. Copy or download the result when the tool provides that action.

How it works

Lines are normalized for comparison, the first original spelling is retained when requested, and the remaining values are sorted alphabetically or numerically.

Common uses

  • Deduplicate domains, IDs, or email addresses
  • Sort a product or country list
  • Remove repeated entries before a CSV import

What the free tool includes

  • Alphabetic or numeric sort
  • Case-aware deduplication
