No. All processing happens in your browser.

Does Japanese text sort correctly?

JavaScript's localeCompare is used, so Japanese text is sorted in Unicode order (hiragana, katakana, kanji). This may differ slightly from traditional 50-on (gojuuon) order.

How does numeric sort work?

If a line can be parsed as a number, it is compared numerically. Lines that are not numeric fall back to string comparison.

What is the 'No sort' option for?

It applies options like deduplication or blank line removal without reordering the lines, which is useful when you only want to clean up the list.

How are symbols and tabs sorted?

Sorting follows Unicode code point order. Symbols and digits generally come before letters.
