FAQ

QWhat is natural sort?

Strings with numbers sort numerically—item2 before item10, not lexicographic.

QWhich duplicate is kept?

Keeps first occurrence; case-insensitive treats Apple and apple as duplicates.

QReverse vs Z-A?

Reverse flips original order; Z-A is alphabetical descending.

QLine limit?

Modern browsers handle tens of thousands of lines; split very large inputs if slow.

QIs data uploaded?

Text is processed locally; nothing is uploaded.

Sort and dedupe text lines
