Put Any List of Lines Into the Order You Actually Need

To sort lines of text quickly without opening a spreadsheet or writing a script, paste them into this tool and pick how you want them arranged — alphabetically, by length, numerically, or shuffled at random. The reordering happens the instant you type or paste, right in the browser tab, and there's no upload, no account, and no cap on how many times you run it.

Most of the time this need shows up somewhere unglamorous: a list of names collected from a form needs alphabetizing before it goes into a report, a set of product IDs needs numeric ordering before a lookup, or a batch of entries needs shuffling so nobody can tell what order they were originally submitted in. Doing any of that by hand past a dozen or so lines is slow and error-prone; a dedicated sorter turns it into picking a mode and letting the tool handle the comparisons.

The Six Ways This Tool Can Order Your Lines

Each sort mode answers a different question about how "in order" should be defined:

• A→Z. Standard alphabetical order, comparing each line as text from the beginning.
• Z→A. The exact reverse of alphabetical order, useful when you want the end of the list to surface first.
• Short→Long. Orders lines by character count, shortest first — good for spotting the briefest entries in a list or preparing data where line length matters, like column formatting.
• Long→Short. The same measurement in reverse, longest entries first.
• Numeric. Reads each line as a number where possible and orders by value rather than by the text characters, so "9" correctly comes before "10" instead of after it the way plain alphabetical sorting would place it.
• Shuffle. Randomizes the line order completely, which is the option to reach for when you need an unbiased random arrangement rather than any predictable ordering at all.

Alongside the six modes, four toggles adjust the details: ignore case makes the alphabetical comparisons treat uppercase and lowercase letters the same instead of sorting capital letters before lowercase ones; remove empty strips blank lines out before sorting; remove duplicates collapses exact repeats down to a single copy as part of the same pass; and trim whitespace clears leading and trailing spaces from every line before anything else happens. A status line above the result confirms how many lines were sorted and whether any blanks or repeats were removed along the way.

Real Situations Where Line Order Matters

A sorted list isn't just tidier — in a lot of cases the order changes what the list is useful for:

• Alphabetizing a roster, glossary, or contact list so a reader can scan for a specific name or term without reading the whole thing top to bottom.
• Ordering product SKUs or invoice numbers numerically before importing them somewhere that expects sequential IDs, since a plain text sort would scatter "2," "20," and "200" apart from each other.
• Ranking entries by length before formatting them into fixed-width columns, since knowing the shortest and longest lines up front makes column width decisions easier.
• Randomizing the order of quiz questions, raffle entries, or survey options so that position in a list doesn't bias the outcome or reveal how the data was originally entered.
• Preparing two lists for comparison. Diff tools work far better on data that's already in a consistent order, so sorting both lists the same way before comparing them cuts down on false differences that are really just ordering mismatches.

Under the Hood: How Each Sort Mode Actually Compares Lines

The alphabetical modes use locale-aware string comparison, which means accented letters and different alphabets are ordered the way a reader would naturally expect rather than by raw character code — a distinction that matters more than it sounds like once names with accents or non-English characters are in the mix. Numeric mode parses each line as a floating-point number for comparison purposes; a line that can't be parsed as a number at all falls back to alphabetical placement, and lines that are entirely non-numeric are pushed toward the end of the ordering rather than being dropped.

Sort mode	What it's comparing	Good fit for
A→Z / Z→A	Full line text, character by character	Names, tags, general word lists
Short→Long / Long→Short	Character count of each line	Column widths, spotting outlier entries
Numeric	Parsed numeric value, not literal digits	IDs, prices, measurements, scores
Shuffle	Nothing — order is randomized	Fair random ordering, sampling

Worth being honest about the shuffle mode specifically: it uses a straightforward random comparison function to reorder lines, which is entirely adequate for everyday randomizing — quiz order, casual raffles, sample ordering — but it isn't a cryptographically secure shuffle, so it shouldn't be the mechanism behind anything like a security-sensitive lottery draw or a use case where the randomness itself needs to be provably unbiased under scrutiny. For that narrower category of use case, a purpose-built cryptographic randomization method is the safer choice.

A Worked Example: Why the Right Mode Matters

Take a small list of product codes: SKU-9, SKU-100, SKU-23, SKU-2. Run that through A→Z and the result reads SKU-100, SKU-2, SKU-23, SKU-9 — technically alphabetical, since string comparison reads character by character and "1" sorts before "2" regardless of what follows it, but almost certainly not the order anyone actually wants for a list of product codes. Switch to numeric mode instead and the portion of each line that parses as a number drives the comparison, producing SKU-2, SKU-9, SKU-23, SKU-100 — the order a person would expect if asked to arrange these by size.

The same gap shows up with version numbers, invoice IDs, page numbers, and anything else where the meaningful value is numeric but the line also contains letters or punctuation around it. It's a small distinction until a report or spreadsheet gets built on top of the wrong ordering, at which point "sorted" and "sorted the way it needed to be" turn out to be two different things — which is exactly why this tool separates plain alphabetical sorting from numeric sorting as distinct modes rather than trying to guess which one you meant.

Length-based sorting solves a different kind of problem entirely. Imagine a list of city names being prepared for a dropdown menu where column width is fixed — sorting by Short→Long surfaces "Rome" and "Lima" before "Buenos Aires" and "San Francisco," making it easy to spot which entries will need extra space or truncation before the layout is finalized. None of the other five modes would reveal that information nearly as directly, since alphabetical order has nothing to do with how long an entry actually is.

Alternatives for Sorting a List of Lines

A few other paths lead to the same ordered result, depending on where your data already sits:

• Spreadsheet sort functions. Google Sheets and Excel handle sorting well once data is already in cells, including multi-column sorts this tool doesn't attempt since it treats each line as a single unit.
• Database ORDER BY clauses. If the list originates from a database query, sorting it there before export avoids the extra step entirely.
• The command line. The Unix sort command handles alphabetical and numeric ordering (with the -n flag) from a terminal, and chains easily into a larger shell pipeline.
• Code editor commands. VS Code, Sublime Text, and several other editors include a built-in "sort lines" command, convenient when the list is already open as a file you're editing.
• The API. For sorting that needs to run automatically as part of a larger workflow — a data import job, a report generator, a scheduled script — this same sorting logic is available as a metered endpoint; details on the request format and credit cost are in the API documentation.

Everything Happens On Your Device

Sorting runs as JavaScript executing directly in your browser tab — nothing you paste into this tool gets sent to a server, logged, or stored anywhere. That's true whether you're sorting a public list of blog categories or something more sensitive, like an internal roster or a list of client names, since the comparison and reordering both happen locally without any network request carrying your data anywhere.

Why does "10" sort before "9" sometimes?

That happens under alphabetical sorting, which compares text character by character — "1" comes before "9" as a character, regardless of the full number. Switch to numeric mode if you want lines compared by their actual numeric value instead.

Can I sort by a specific column if my lines have multiple fields?

Not directly — each line is sorted as a whole unit of text. If you need to sort by one field within a delimited line, that field needs to be first in the line, or the data should be handled in a spreadsheet where columns can be targeted individually.

What happens to lines that are identical after sorting?

They stay in the result side by side unless "remove duplicates" is turned on, in which case only one copy of each exact repeat survives the pass.

Is the shuffle mode truly random each time?

Each click produces a fresh random ordering using standard randomization, which is fine for everyday shuffling needs, though it isn't built to the cryptographic standard required for high-stakes drawings or provably fair lotteries.

Does sorting affect the original casing of my text?

No. The ignore case option only changes how lines are compared during sorting — the letters themselves are output exactly as typed, uppercase and lowercase intact.

Can I undo a sort if I want my original order back?

The tool itself doesn't keep an undo history, so it's worth keeping a copy of your original list elsewhere before sorting if you might need the original order again later.

Do I need to sort lines before or after removing duplicates?

Either order works, since both operations can run in the same pass here: turn on remove duplicates alongside whichever sort mode you need, and the tool strips repeats and reorders the remaining lines together rather than requiring two separate steps.

Tools That Pair Well With Sorting

Most of the time, the reason to sort lines in the first place is to feed the result into some other step — a report, a comparison, or a formatted document — so it rarely stands alone as the only cleanup a piece of text needs. Duplicate Line Remover handles repeat detection with more granular controls, including whether the first or last occurrence of a repeat survives. Text Column Formatter is a natural next step once lines are sorted by length and need to be aligned into readable columns. Random Text Generator is useful if you need fresh sample data to sort and test with rather than randomizing an existing list. And Text Diff Checker confirms exactly what moved once two sorted lists are compared side by side.
