Frequently Asked Questions
Does case sensitivity affect deduplication?
By default, comparison is case-sensitive ("Apple" and "apple" are different). Enable "Ignore case" to treat them as the same line.
Does order matter?
When "Sort lines" is disabled, the first occurrence of each line is kept in its original position. Enable sorting to get alphabetically ordered output.
