How it works

Paste text with duplicate lines — from logs, data exports, transcript errors, or merged documents. The tool scans each line, keeps only unique entries, and shows you how many duplicates were removed. All processing happens in your browser.

Common use cases

  • Cleaning up duplicate entries in log files
  • Deduplicating merged lists or data exports
  • Removing repeated lines from transcripts
  • Finding unique values in any text-based dataset
// FAQ
How does duplicate detection work?
The tool scans each line of your text and keeps only the first occurrence. By default, comparison is case-insensitive and whitespace is trimmed, so 'Hello' and 'hello' are treated as the same line.
Does it preserve the original line order?
Yes. The first occurrence of each unique line is kept in its original position, and subsequent duplicates are removed. The order of your text is fully preserved.
Can I make it case-sensitive?
Yes. Enable the 'Case sensitive' option to treat 'Hello' and 'hello' as different lines. This is useful when case carries meaning in your text.
