Sort lines online alphabetically, numerically, or in reverse order using this free browser-based tool. Paste any list or multi-line text and get sorted output instantly without installing software or creating an account. Useful for organizing word lists, tag collections, name lists, configuration entries, and any line-by-line content that needs consistent ordering.
The Line Sorter arranges lines of text in alphabetical order, reverse alphabetical order, by line length (shortest first or longest first), or randomizes them. You can choose between case-sensitive and case-insensitive sorting, enable natural sort order (which sorts numbers in text as numbers rather than characters, so "item10" comes after "item9" not after "item1"), and choose whether to keep or remove blank lines during sorting. This tool is useful for sorting lists of names, keywords, file paths, CSS rules, import statements, or any text where order matters. Natural sort order is particularly important for numbered lists and version numbers (1.2.10 should sort after 1.2.9, not between 1.2.1 and 1.2.2).
Line sorting has more practical applications than it might initially appear. For CSS, sorting properties within a declaration block alphabetically (a common style guide recommendation) makes it easier to find a specific property in a long rule. For import statements in JavaScript, TypeScript, or Python, sorting imports alphabetically makes it easy to see at a glance whether a module is already imported and reduces merge conflicts in version control (when two developers both add imports, alphabetical order means their changes are more likely to be in different positions in the file). For keyword lists used in SEO, content planning, or advertising campaigns, alphabetical sorting makes it easy to review, remove duplicates, and identify gaps. Natural sort order solves the "computer sort" problem where "chapter 10" sorts before "chapter 2" because "1" comes before "2" in ASCII order. Natural sort handles this correctly by extracting and numerically comparing the numeric portions. Random shuffle is useful for creating random presentation orders (who presents first in a group project), randomizing A/B test variants, or generating random question orders for a quiz. The case-insensitive option treats uppercase and lowercase versions of a letter as equal for sorting purposes, which means "banana", "Apple", and "cherry" sort as apple, banana, cherry in alphabetical order regardless of capitalization.
