Does it ignore case when comparing lines?

No — comparison is case-sensitive by default, so lines that only differ in capitalization are kept as separate entries.

Does it ignore extra spaces?

No — lines are compared exactly as typed. Use the Remove Extra Spaces tool first if you need to normalize whitespace.

No — the first occurrence of each unique line keeps its original position.

Remove duplicate lines from a list. Paste your text and get back only the unique lines, in the order they first appeared.

Keeps the first occurrence of each line and preserves the original order.
Comparison is exact and case-sensitive, so "Apple" and "apple" are treated as different lines.
