• Split CSV: Parse comma, colon, semicolon, or tab-separated data
• Pre-Processing Options: Case sensitivity toggle, space normalization, and custom find-and-replace rules
• Export & Utilities: Export results as .txt or .xlsx, copy to clipboard, sort, and deduplicate
• Privacy-Focused: Your lists are processed on your device and are not sent to our servers
