List Randomizer

Each shuffle draws its numbers from crypto.getRandomValues, the cryptographic random source built into your browser, and turns them into positions with the Fisher–Yates method and rejection sampling. Every order of your list is equally likely. The list randomizer doesn’t use atmospheric noise like RANDOM.ORG, but for classroom turns, raffles and team picks the result is just as fair.

Because random orders often look unshuffled. In a list of 10, about two shuffles in three leave at least one item exactly where it started (1 − 1/e, roughly 63%), and only about 37% move every item. Two or three neighbours that stay next to each other are just as normal.

Yes, unless a seed is switched on. Each press draws fresh random numbers, so the same order can come back only by chance: about 1 in 3.6 million for a list of 10. With a seed, the same list always gives the same order on purpose.

RANDOM.ORG’s list page uses atmospheric noise collected on its servers and returns one order. This list randomizer shuffles in your browser with cryptographic randomness, and adds winners with alternates, even groups, two-list matching, seeds you can re-check, share links that keep the exact order and a full-screen Present view.

Open Make groups and choose either the number of groups or how many people go in each. When the list doesn’t divide evenly you choose between even groups (10 people in threes gives 4, 3, 3) and full groups plus one smaller group (3, 3, 3, 1). Choosing a number of groups always gives sizes that differ by at most one.

There is no spinning wheel here. A wheel picks one entry with a random number, the same as Pick winners with one winner, and adds an animation. For a room that wants suspense, press Present after a draw: it shows one name at a time, full screen, and you reveal the next one with the space bar.

Paste the class roster, one student per line, and press Shuffle list for a speaking or presentation order. Use Make groups for group work, and Present to show the order on the board one student at a time. The roster stays in the browser tab, so it is not uploaded.

Open Pick winners and leave Winners at 1. Press the button again for another pick from the full list, or use Remove drawn from list first if the same name shouldn’t come up twice.

Use Make groups with 2 people per group. With an odd number of people the extra person joins one pair, so 7 people give 3, 2 and 2. To pair people from two different lists, such as mentors and mentees, use Match lists.

Yes. It runs in any current browser, including Chrome on a Chromebook and Safari on an iPad, with nothing to install. On an iPad the list and the result sit side by side in portrait as well as landscape.

It works by copy and paste. Copy the names from your class roster or a Google Sheet, paste them in, and paste the result back into a Classroom post or a Doc. Nothing connects to your Google account.

Paste one question per line and shuffle. For a different order per student, use a different seed for each and write the seed on the sheet, so you can rebuild any student’s order later.

Press Present after a draw. It fills the screen with one name (or one group) at a time in large type, and you move on with the space bar or the arrow keys, or by tapping Next.

Use Match lists: put the students in the first box and the seat labels (A1, A2, B1 …) in the second. Each student gets a random seat, and the CSV gives you a table to print.

It shows no ads, asks for no sign-up and doesn’t upload the names you paste or the files you open; they stay in the browser tab. The site counts page visits without recording any list, as the privacy policy explains.

Turn on “Let others re-check this draw” and announce the seed before you draw, for example in your giveaway post. After the draw, send the share link. Anyone who opens it can press “Re-run seed and compare”, and the list randomizer repeats the whole shuffle and tells them whether it matches.

Paste an entry once for every chance it should get, and keep Duplicates set to Keep. Someone listed three times is three times as likely to be drawn first. In Pick winners they can then win more than one place, so remove their extra lines after they win if each person may only win once.

For giveaways, classroom prizes and club raffles, a fair shuffle with a published seed is plenty. Regulated lotteries and sweepstakes have their own rules, which can require certified equipment or an independent witness, so check what applies where you are before relying on any website.

Not well. In a Secret Santa nobody may draw their own name, and matching a list against itself can pair someone with themselves, so the list randomizer would need re-runs until no one does. A dedicated Secret Santa tool handles that rule, and exclusions such as couples, for you.

Shuffle the team or player names for a draft order or first-round pairings. Turn on a seed and share the link so every team can check the order wasn’t changed afterwards.

It can’t read Instagram for you. Copy the usernames from the comments into the box (one per line), remove duplicates if each person gets one entry, and draw. Use a seed and share the link so commenters can check it.

Paste the attendees and shuffle for a stand-up or round-robin order, then Copy numbered into the meeting chat.

Up to 100,000 items per list. Ten thousand names shuffle in well under a second on a laptop. The page shows the first 30 rows of a shuffle and more when you ask (Show all, or 5,000 at a time for very long lists; Pick winners lists up to 2,000 of the undrawn entries). Copy and the CSV include every item (in Pick winners, Copy gives the winners and alternates and the CSV lists everyone); share links stop at about 60,000 characters (roughly 8,000 short names), so very long lists are better sent as a CSV file.

Kept by default, because two people can share a name and a raffle can give someone two entries. The counter above the box tells you how many repeats it found (capitals and spaces aside, so @Fatima.R and @fatima.r count as one) and offers to remove them. Choose “Remove exact repeats” or “Remove, ignoring case” under Duplicates to keep only the first copy of each.

Open More options and use Fill with numbers to put a range such as 1 to 30 into the box, then shuffle it or draw as many numbers as you need in Pick winners. Each number is drawn once, so there are no repeats, which suits seat numbers, ticket stubs and bingo calls.

Yes, when items are split at new lines, which Auto does for any list of more than one line. A row copied from Excel or Google Sheets arrives as one line with tabs between the cells, so the whole row moves as one item.

Every line is treated as plain text, so email addresses, URLs and usernames are shuffled like any other item. Links aren’t opened or checked, and addresses aren’t sent anywhere.

Accents (José, Zoë), other scripts (Chinese, Arabic, Cyrillic, Hindi) and emoji are kept exactly as typed, in the result, the copied text and the CSV. (The one change: in the CSV, a cell starting with =, +, - or @ (other than a plain number such as -5) gets an apostrophe in front, because Excel and Google Sheets would otherwise run it as a formula and show an error. Excel shows that apostrophe, so @ken appears as '@ken there; Copy and the text file keep handles exactly as typed.) The CSV starts with a byte-order mark so Excel opens it as UTF-8 instead of garbling the accents.

Shuffling never changes your list: it stays in the box, and every row of a shuffle or a draw shows the place it came from (“was 4”, or the small number at the start of its line). Clear the list, Remove drawn from list, a sample button, Fill with numbers and opening a file over a list change the box, and each shows an Undo link next to the item count until you type. To go back to an earlier result, keep its share link or download it before drawing again, because each new draw replaces the one on screen.

Shuffling 100,000 items takes well under a second on a laptop. The page shows the first rows and adds the rest when you ask; Copy and the CSV include the whole list (in Pick winners, Copy gives the winners and alternates; the CSV has everyone).

Each row arrives as one line. If you copied several columns, each row stays together, and when the first row looks like column names (Name, First Name, or headings over rows of numbers) the page offers to leave it out of the draw (Shuffle’s copied text keeps it as the first line, and the CSV uses it as column names). The CSV download splits the columns again.

Press Open a file under the box, or drop the file on the box. It reads .xlsx, .csv (comma or semicolon), .tsv and .txt. A file with one column goes straight in (unless Excel hid some of its rows, which the page tells you about first); with several, you tick the columns that hold the names (first and last name can be joined into one name, in either order) and choose whether the first row is column names. Title lines above the column names (as in school roster exports) are left out, rows hidden by an Excel filter are skipped, a workbook with several sheets lets you pick the sheet, and dates come in the way the cell shows them (3/1/2013). In Match lists, a two-column file can fill both lists at once. Files up to 20 MB open; the file is read in your browser and never uploaded. Word, PDF, old .xls files and photos can’t be read; save the list as .xlsx or .csv, or copy and paste it.

When your list has one name per line, commas inside a line stay put, so “Smith, John” is one entry. Only a single line of items is split at commas (or at semicolons, if it has any).

There is no print layout yet. Copy the result into a document, or open the CSV in Excel or Google Sheets, and print from there.

Paste the song titles, one per line, and shuffle. Copy the new order back into your notes or playlist app; the site doesn’t connect to music services.

Nowhere. Parsing, shuffling, copying and downloads all happen in your browser. Your list is only kept in this tab’s session storage so a reload doesn’t lose it. A share link carries the list inside the part of the address after #, which browsers don’t send to the server.

No install is needed. The page works in any phone browser, and the input, the button and the result fit a narrow screen. On iPhone use Share, then Add to Home Screen; on Android use the browser menu’s Add to Home screen, and it opens like an app.

Once the page has loaded, shuffling, groups, copying and downloads need no connection, because they all run in the browser. Sending feedback and opening the other pages do need one.

Yes. There is no sign-up, no paid tier and no advertising. It is run by one independent developer.

The list stays in the box while the tab is open, even after a reload. For anything longer, keep the list in a document or spreadsheet, or download the result as CSV or text. Nothing is saved between visits on purpose, so a shared computer doesn’t keep your class list.

One independent developer, not a company, who tested the ten tools Google showed first for this search before building it. The About page has the details and what it can’t do.

No. There is no sign-up, no login and no paid tier. Open the page, paste and press the button.

Every control is a labelled button or field you can reach with Tab, Ctrl+Enter (Cmd+Enter on a Mac) in the list box runs the draw, and Present works with the arrow keys, the space bar and Esc.
