Where duplicates come from
Duplicates are common when you merge spreadsheets, scrape data from multiple sources, or manually combine text blocks.
Simple cleanup workflow
1. Paste lines into a text field.
2. Normalize spacing and case if needed.
3. Remove exact duplicate lines.
4. Compare old vs cleaned version to confirm changes.
Tips for better quality
Keep one value per line. Trim spaces. Decide whether case differences (Example vs example) should be treated as duplicates.
