Streamline Your Text: Remove Duplicate Lines Instantly

Clean up lists, code, logs, or any text data effortlessly with our free online Duplicate Line Remover. This powerful tool identifies and eliminates repeated lines based on your chosen criteria, leaving you with unique, organized content.

Why Remove Duplicate Lines?

• Data Cleaning: Ensure accuracy and efficiency by removing redundant entries from datasets, CSV files, or contact lists.
• List Management: Create unique lists for email campaigns, inventory management, or keyword analysis.
• Code Optimization: Deduplicate import statements, configuration lines, or other repeated code snippets.
• Log Analysis: Focus on unique events or errors by filtering out repetitive log entries.
• General Text Editing: Quickly tidy up any document where lines have been accidentally repeated.

Flexible Deduplication Options:

• Case Sensitivity: Choose whether 'Line' and 'line' should be treated as identical or distinct.
• Whitespace Trimming: Ignore leading/trailing spaces to find duplicates like ' item' and 'item '.
• Order Preservation: Keep the first occurrence of each line in its original position.
• Blank Line Handling: Decide whether to keep or remove empty lines during deduplication.
• Isolate Duplicates: Optionally, keep *only* the lines that were duplicated in the original text.

1. Paste your text containing potentially duplicate lines into the 'Input Text' box.
2. Select your desired options (Case Sensitive, Trim Whitespace, etc.).
3. Click the 'Remove Duplicates' button.
4. The cleaned text with unique lines (or only duplicates, if selected) will appear in the 'Result' box.
