About This Tool
When you work with lists, server logs, or data from multiple sources, you often end up with duplicate entries. This tool quickly removes duplicate lines while preserving the order of first occurrence, giving you a clean, deduplicated list.
Use case-sensitive mode for strict matching, or disable it to treat different capitalizations as the same. Use trim mode to ignore leading and trailing spaces when comparing lines. This flexibility makes it work with almost any text format.
