Remove Duplicate Lines
Paste any list or text and strip out the repeated lines. The first occurrence of each line is kept and the order is preserved. Options let you treat "Apple" and "apple" as the same line, ignore surrounding spaces, and drop empty lines.

Frequently asked questions
Does it keep the original order?
Yes. The first occurrence of every line stays exactly where it was; only later repeats are removed.
What counts as a duplicate?
By default, lines that match exactly. Turn off case sensitivity to treat different capitalizations as duplicates, or turn on trimming to ignore leading and trailing spaces.
Can I remove duplicates from a spreadsheet column?
Yes — copy the column, paste it here, clean it, and paste the result back. One value per line is all it needs.
