Text Sorter

The Text Sorter is a free online tool that reorders the lines of any text you paste, all inside your browser. Choose alphabetical (A–Z or Z–A), numerical (ascending or descending), natural “human” ordering, sort by line length, or simply reverse and shuffle — then copy or download the result.

Everything runs client-side, so your text never leaves your device: no uploads, no accounts, and no server ever sees what you paste. A live line count and a separate output area let you sort thousands of lines instantly while keeping your original intact.

How to sort text online

1. Paste or type your content into the Text to sort box, one item per line.
2. Pick a Sort method — alphabetical, numeric, natural, by length, reverse, or shuffle.
3. Toggle Case-insensitive sorting, Trim whitespace, and Remove blank lines to clean the input as it sorts.
4. Click Sort Lines and watch the live line count update.
5. Use Copy or Download to save the sorted output as a .txt file.

What is a text sorter?

A text sorter takes a list of lines and arranges them into a defined order — alphabetical, numeric, or by another rule — in a single pass. It is the quickest way to alphabetize a list of names, order a set of IDs, tidy a glossary, or randomize entries without dragging rows around by hand.

What is natural (numeric-aware) sorting?

Plain alphabetical sorting compares text character by character, so item2 lands after item10 because “1” comes before “2”. Natural sort reads the numbers inside each line as actual values, giving the human-friendly order item1, item2, item10. This tool uses the browser's built-in Intl.Collator with its numeric option, so natural ordering is accurate and locale-aware without any external library.

Alphabetical vs. numeric vs. length sorting

Use alphabetical for words and general lists, numeric when each line's numeric value is what matters (it reads the first number in the line and floats non-numeric lines to the end), and by length to group short and long lines together. Reverse flips whatever order you already have, and shuffle randomizes every line — handy for sampling, quizzes, or breaking up a predictable list.

Text Sorter features

• Alphabetical A–Z and Z–A ordering for any list.
• Numerical and natural (numeric-aware) sorting for IDs, versions, and mixed text.
• Sort by line length, plus reverse and shuffle.
• Case-insensitive toggle so Apple and apple group together.
• Trim whitespace and remove blank lines to clean input on the fly.
• Live line count and a non-destructive output area with Copy and Download.

When to use this vs. other text tools

Text Sorter is built for one job — ordering lines — and it stays focused on that. It is distinct from tools that change which lines you keep or what they contain: to collapse repeated entries, the Remove Duplicate Lines tool deduplicates rather than reorders, and to add the same text to the start or end of every line, reach for Line Prefix & Suffix. When you need to swap words or patterns, Find and Replace Text is the right fit, and to change letter case across your list, the Case Converter handles uppercase, lowercase, and title case. If you just want to measure a block of text, the Word Counter reports words, characters, and lines. Each tool does one thing well, so pair them as needed — sort here, then dedupe or prefix elsewhere.

Frequently Asked Questions

Is my text uploaded to a server?

No. All sorting happens locally in your browser with client-side JavaScript. Your text is never sent to, stored on, or seen by any server.

What is the difference between alphabetical and natural sorting?

Alphabetical sorting compares characters left to right, so item10 comes before item2. Natural sorting reads the numbers inside each line as values, producing the human order item1, item2, item10. Choose the natural option for lists that mix words and numbers.

How does numeric sorting handle lines without numbers?

Numeric mode reads the first number it finds in each line and sorts by that value. Lines that contain no number are pushed to the end and ordered alphabetically among themselves, so the list stays predictable.

Does the tool change my original text?

No. Your input box stays exactly as you left it. Sorted lines are written to a separate output area, so you can compare the two, change options, and sort again as many times as you like.

How is this different from Remove Duplicate Lines?

Text Sorter only reorders lines; it does not delete any. Remove Duplicate Lines is a separate tool that strips repeated entries. You can sort first and dedupe afterward, or the reverse, depending on the result you want.

Is there a limit on how many lines I can sort?

There is no fixed limit. Because everything runs in your browser, the practical ceiling is your device's memory, and lists of thousands of lines sort almost instantly.
