Sort Lines

It takes the list you paste and reorders every line according to your chosen sort — alphabetically, numerically, or by length — in either ascending or descending order. It is perfect for organizing name lists, keywords, prices, log entries, IPs, or any other column of text you want in a predictable order.

Alphabetical sorts by letters, so "10 apples" comes before "2 oranges" because "1" sorts before "2" as text. Numerical sorts by the number a line starts with, so "2 oranges" correctly comes before "10 apples". By length sorts from the shortest line to the longest (or the reverse), which is useful for finding short vs long entries like filenames or passwords.

Natural sorting understands numbers embedded inside text, so "item2" sorts before "item10" — just like a human would expect. Without it, a plain alphabetical sort would put "item10" before "item2" because "1" is smaller than "2". This is enabled by default and makes file lists and version numbers sort sensibly.

When enabled, "Apple" and "apple" are treated as the same for ordering purposes, which usually matches how people expect lists to be sorted. When disabled, uppercase letters are compared separately, so "Apple" would sort before "banana" but after "Zebra" depending on the exact letter codes.

"Remove duplicates" drops repeated lines so each line appears once in the sorted output. "Remove empty lines" removes blank lines entirely. Both are off by default; enable them when you want a clean, deduplicated, tightly-packed result instead of preserving every line you pasted.

By default blank lines are kept and sorted into the result — empty strings sort to the top in ascending order and to the bottom in descending order. If you would rather not see them at all, turn on "Remove empty lines" and they will be dropped and counted in the statistics panel.

Yes. Sorting runs entirely in your browser using the built-in optimized sort, so even lists with tens of thousands of lines are reordered in milliseconds. Because everything happens locally, there is no file size limit imposed by an upload or a server.
