Frequently Asked Questions

Does it preserve order?
Most tools keep the first occurrence and remove later duplicates, preserving the original order. Some offer 'keep last' or 'remove all duplicates' options.
Is it case-sensitive?
By default, duplicates are usually case-sensitive ('Hello' and 'hello' are different). Some tools offer case-insensitive deduplication.
What about near-duplicates?
This tool removes exact duplicates only. For similar but not identical lines (e.g., typos), you'd need a fuzzy matching or diff tool.
