Sort Lines

Line sorting organizes unordered text into a predictable sequence. Paste a list of names, numbers, URLs, or code lines and sort alphabetically (A–Z or Z–A), numerically (smallest to largest), by line length, or in random shuffled order. Sorted data is easier to scan, compare, and merge with other datasets.

Alphabetical sorting uses Unicode code point order by default — uppercase letters sort before lowercase in many locales unless case-insensitive mode is selected. Numeric sort interprets entire lines as numbers when possible, so "2" correctly precedes "10" instead of appearing after it as in plain alphabetical order. Reverse sort flips any order; random shuffle randomizes for contests, sampling, and test data generation.

Combine sorting with duplicate removal: sort first to visually group identical lines, then deduplicate. The find-and-replace tool fixes content within lines; sorting reorders lines without changing their text. Developers sort package dependencies, environment variables, and test fixtures for consistent diffs in version control.

Case-insensitive sorting treats "banana" and "Banana" as equal for ordering purposes. Trim options ignore leading and trailing whitespace when determining sort keys. Empty lines sort to the top or bottom depending on implementation — review output when blank rows matter.

Whether you are alphabetizing bibliography entries, ordering numbered steps, randomizing team assignments, or preparing clean CSV data, line sorting transforms chaotic pasted lists into structured readable output.
