About Duplicate Line Remover

The Duplicate Line Remover tool helps you clean up text by removing repeated lines. It's perfect for cleaning data, organizing lists, and preparing text for further processing.

How to Use

1. Paste your text with duplicate lines in the input box
2. Configure your options (case sensitivity, whitespace handling, etc.)
3. Click "Remove Duplicates" to process the text
4. Copy or download the cleaned result

Options Explained

• Case Sensitive: When enabled, "Text" and "text" are considered different lines. When disabled, they're treated as the same line.
• Trim Whitespace: Removes extra spaces at the beginning and end of each line before comparison.
• Ignore Empty Lines: Skips blank lines when processing.
• Keep First Occurrence: When enabled, keeps the first occurrence of a duplicate line. When disabled, keeps the last occurrence.
