Clean Up Your Lists
Duplicate data is a common formatting error when extracting email lists, CSV data, or inventory logs. The Remove Duplicates tool helps you clean this data in seconds.
Features
- Line Mode: Treats each new line as a separate item. Perfect for lists of names or emails.
- Word Mode: Scans the entire text and removes repeated words, leaving only the unique vocabulary.
- Trim Support: Automatically removes accidental spaces at the beginning or end of lines so " Apple" and "Apple" are treated as duplicates.
- Case Insensitivity: Choose to treat "Apple" and "apple" as the same item.
Why is De-duplication Important?
Removing duplicates prevents errors such as:
- Spamming: Sending the same email twice to the same person.
- Inaccurate Reporting: inflated counts in inventory or survey data.
- Wasted Space: Reducing file size by eliminating redundant information.
