Text Dedupe

Why Do You Need a Text Deduplication Tool

Deduplication is one of the most common needs in data cleaning and content organization. Lists scraped from websites, exported contacts and user submissions often contain many duplicate lines or characters. Removing duplicates manually is time-consuming and error-prone. This tool supports custom separators, blank-line handling and sorting.

Core Features Explained

1. Mode: Remove all duplicate lines, or only consecutive duplicates.
2. Custom separators: Define input and output separators, e.g. commas or spaces.
3. Line whitespace: Optionally trim leading/trailing whitespace before comparing.
4. Blank lines: Delete, dedupe or keep blank lines.
5. Sort: Sort the result ascending or descending.

How to Use the Tool

1. Enter the text to deduplicate in the left input box.
2. Configure mode, separators, blank-line handling and sorting.
3. Click "Convert" to see the result.
