Free Online Sort Lines Tool

Sort lines of text alphabetically, numerically, by length, or at random — instantly in your browser. Trim whitespace, remove empty lines, then copy or download the result. No sign-up, nothing stored.

What does sorting lines do?

Sorting lines reorders a list of text — one item per line — into a chosen order. The most common is alphabetical (A→Z or Z→A), but you can also sort by the leading number on each line, by line length, or flip and shuffle the order entirely.

This tool runs the sort live as you type and keeps the original input alongside the result, so you can compare and tweak options without losing your data. Everything happens locally in your browser.

Key Features

Alphabetical Sorting

Order lines A→Z or Z→A, with an optional case-insensitive mode for natural, dictionary-style results.

Numeric Sorting

Sort by the leading number on each line using parseFloat; non-numeric lines fall to the bottom.

Sort by Length

Arrange lines from shortest to longest — handy for spotting outliers or tidying lists.

Reverse & Shuffle

Flip the current order instantly, or randomize every line for sampling and quick picks.

Clean As You Sort

Trim whitespace on each line and drop empty lines so the result is ready to use.

100% Client-Side

Your text never leaves the browser. Nothing is uploaded, logged, or stored.

How to Sort Lines

1

Paste your lines

Drop a list into the input box — one item per line. The output updates live as you type.

2

Pick a sort order

Choose alphabetical, numeric, by length, reverse, or shuffle from the order dropdown.

3

Tune the options

Toggle case-insensitive matching, trim whitespace, and remove empty lines to fit your data.

4

Copy or download

Grab the sorted result with one click, or download it as a .txt file. Clear resets the input.

Common Use Cases

  • Tidy lists: Alphabetize names, tags, imports, or to-do items so they read in a predictable order.
  • Sort numeric data: Order prices, scores, IDs, or measurements by their leading number, ascending or descending.
  • Deduplicate prep: Remove empty lines and trim whitespace before pasting into a diff or dedupe tool.
  • Randomize selections: Shuffle a list to draw a winner, randomize test order, or sample entries fairly.
  • Clean up code & config: Sort import statements, env keys, or dependency lists to keep files consistent.

Frequently Asked Questions

How does numeric sorting handle non-numeric lines?

Each line is parsed with parseFloat, which reads the leading number. Lines that do not start with a number are treated as non-numeric and always sort after the numeric lines, in alphabetical order among themselves.

What does the case-insensitive option do?

When enabled, alphabetical sorting ignores letter case, so "Apple" and "apple" are ordered together as if they were the same. Turn it off to sort with case sensitivity, which can separate upper- and lower-case entries.

What is the difference between Reverse and Z→A?

Z→A sorts the lines alphabetically in descending order. Reverse simply flips the current order of the lines as they appear in the input, without sorting them — useful for inverting an already-arranged list.

Is the shuffle truly random?

Shuffle uses a Fisher-Yates algorithm driven by the browser's Math.random, which is fine for everyday randomization like drawing names or sampling. It is not cryptographically secure, so do not use it for security-sensitive draws.

Why do the input and output line counts differ?

Sorting alone keeps the same number of lines. The counts change when you enable "Remove empty lines", which drops blank lines from the result, so the output can have fewer lines than the input.

Is my text uploaded anywhere?

No. All sorting happens entirely in your browser with JavaScript. Your text is never sent to a server, stored, or logged — close the tab and it is gone.
