Remove duplicate lines from text and keep only unique lines
This tool identifies and removes duplicate lines from your text, keeping only unique entries. It compares lines based on your selected options (case sensitivity, whitespace handling) and preserves the first occurrence of each unique line while removing subsequent duplicates.
When case sensitive is enabled, "Apple" and "apple" are treated as different lines. When disabled, they're considered duplicates and only one will be kept.
The tool keeps the first occurrence of each unique line and removes all subsequent duplicates. The original order is preserved unless you enable alphabetical sorting.
