Text Sorter Online
Sort lines alphabetically, by length, or naturally. Remove duplicates and filter blank lines.
What Is a Text Sorter?
A text sorter takes a block of text and rearranges its lines according to a chosen sort order. This online text sorter supports alphabetical sort, sort by line length, and natural sort — which correctly orders lines containing numbers (e.g. file2 before file10). It also supports deduplication to remove repeated lines, case-insensitive comparison, whitespace trimming, and filtering of blank lines. All processing runs in your browser — no data leaves your machine.

FAQ
What is a text sorter?
A text sorter is a tool that rearranges lines of text in a specified order — alphabetically, by line length, or using natural sort (which handles numbers correctly, e.g. item2 before item10). It can also remove duplicate lines.
What is natural sort order?
Natural sort order treats embedded numbers as numeric values rather than character sequences. For example, "file10" comes after "file9" in natural sort, but before it in alphabetical sort (because "1" < "9" as characters).
How does deduplication work?
Deduplication removes lines that appear more than once, keeping only the first occurrence. When "Ignore Case" is also enabled, lines that differ only in capitalization (e.g. "Apple" and "apple") are treated as duplicates.
