About Text Deduplicator
Text deduplication is a common task in data processing and list cleaning. When merging multiple lists, cleaning email lists, or processing extracted log data, deduplication is essential. This tool offers three modes: keep first occurrence (for ordered lists), keep last occurrence, and keep only unique items (removing all duplicates). Simple and intuitive, with real-time line count comparison before and after deduplication.
