Sort Lines

This tool splits your text on line breaks and reorders the resulting lines alphabetically, either A-to-Z or Z-to-A. Sorting compares lines as strings from left to right, which means it follows character code order rather than a dictionary's sense of alphabetization — numbers sort before uppercase letters, which sort before lowercase letters in standard ASCII-based comparison, so "Zebra" can end up sorted before "apple" if case isn't normalized first, and "10" sorts before "9" because it compares the first character ("1" vs "9") rather than the numeric value.

Line-based sorting is distinct from sorting words within a sentence — each full line, however long, is treated as a single unit to compare against every other line, so this works cleanly on lists (one item per line) but would just reorder whole sentences if applied to prose broken across multiple lines.

Common uses include alphabetizing a list of names or file paths, organizing a glossary or reference list into A-Z order, or reversing a list that's already sorted one way when you need the opposite order for a different display.

Lines are compared as strings from left to right, using character code order and not a dictionary sense of alphabetical order. That is why 10 comes before 2, and uppercase letters sort ahead of lowercase.

For numeric lists, pad numbers with leading zeros or sort in a spreadsheet. For names in languages with accents, character code order may not match local alphabetical rules.
