The Text Deduplication and Separator Tool is a free online utility that removes duplicate lines and items from text data while supporting various separators like commas, semicolons, newlines, tabs, and custom delimiters. It's perfect for cleaning lists, CSV data, and organizing content efficiently.
What separators are supported?
The tool supports comma, semicolon, newline, tab, space, pipe (|), and custom separators. You can input text with any separator and choose a different separator for the output if needed.
Can I preserve the original order of items?
Yes, you can choose to maintain the original order of items or sort them alphabetically in ascending or descending order. The tool provides flexible sorting options to meet your needs.
Is the tool case-sensitive when removing duplicates?
You can choose between case-sensitive and case-insensitive deduplication. Case-insensitive mode treats 'Apple' and 'apple' as duplicates, while case-sensitive mode keeps them as separate items.
