Duplicate Line Remover

Strip duplicate lines from any block of text. Multiple normalization options because "duplicate" means different things — a CSV column wants exact match, an email list wants case-insensitive, a notes file wants whitespace-trimmed.

Nasıl Kullanılır

  1. Paste your lines into the input.
  2. Tick the normalization options that match your use case.
  3. Copy the deduplicated output.

Sık Sorulan Sorular

Why are emails like ALICE@example.com and alice@example.com sometimes treated as duplicates?

When 'Ignore case' is on, they compare equal. Email addresses are case-insensitive in the local part for most providers, so this is usually what you want for cleaning a list.

Does it preserve the first or last occurrence?

First occurrence. The line that appears earliest in the input is kept; later duplicates are dropped.
