About This Tool
This tool scans a block of text line by line and removes exact or near-duplicate entries, while keeping the original order — useful for cleaning up lists, logs, or exported data.
How to Use
- Paste your text into the input box, one item per line.
- Toggle "Case-insensitive" and "Trim whitespace" if you want those applied when comparing lines.
- Review the de-duplicated result and click "Copy" to copy it.
