About Line Deduplicator
Line Deduplicator removes repeated lines from a block of text, trimming whitespace on each line first so near-identical lines with extra spaces are still caught, and reports how many duplicates were removed.
Common Use Cases
- Cleaning up a mailing list or contact list that has repeated entries.
- Deduplicating log lines to see only the unique events.
- Merging two lists and removing the overlap.
Frequently Asked Questions
Is the duplicate check case-sensitive?
Yes — 'Example' and 'example' are treated as different lines and both kept. If you need case-insensitive deduplication, convert the text to a single case first (for example with the Case Converter) before running it through here.
