How to Use List Randomizer — Step by Step
Step 1: Enter your list
Type or paste your items into the input area, with one item per line. You can include names, numbers, tasks, or any text-based list.
Step 2: Click Randomize
The tool applies the Fisher-Yates shuffle algorithm to your list, which guarantees a uniformly random distribution. Every possible ordering of your items is equally likely.
Step 3: Copy the result
The shuffled list appears in the output area. Copy it for use in your project, presentation, or spreadsheet. You can click Randomize again to get a different shuffle.
Step 4: Re-shuffle as needed
Click Randomize multiple times to get different random orderings. The original list in the input area remains unchanged for repeated shuffling.
Real-World Examples
Team Assignment (Manager): You have 12 employees and need to form 6 pairs for a workshop activity. You paste the 12 names, randomize the list, and pair adjacent names: items 1-2 become Team A, 3-4 become Team B, and so on. Fair, fast, and unbiased.
Giveaway Winner (Marketer): You ran a social media contest with 200 entries. You paste all usernames, randomize the list, and the top 3 names are your winners. You take a screenshot for transparency and announce the results.
Study Schedule (Student): You have 8 subjects to review before exams. You paste them, randomize, and study them in the shuffled order. This prevents you from always starting with the same subject and ensures balanced preparation.
Tournament Bracket (Organizer): You have 16 teams for a single-elimination tournament. Randomize the list to determine first-round matchups without seeding bias.
Task Rotation (Team Lead): Your support team has 5 members and 20 tickets. Randomize the member list, then assign tickets in round-robin order for fair distribution.
Playlist Shuffle (DJ): You have a playlist of 50 songs for an event. Randomize the order to create a fresh setlist that feels spontaneous but ensures all songs play once.
Features
- Fisher-Yates shuffle for truly uniform random distribution
- Handles any text-based list: names, numbers, tasks, or mixed content
- Re-shuffle as many times as needed with one click
- 100% private — all randomization happens locally in your browser
- No item limit — works with small lists of 5 or large lists of 500+
- Free forever with no signup, no limits, and no data collection
- Automatically filters empty lines from input
- Preserves original input for repeated shuffling without re-entry
Tips & Best Practices
- One item per line: Ensure each item is on its own line. The tool splits on newlines, so "Item 1, Item 2" on one line counts as a single item.
- Remove empty lines: Empty lines are filtered out. This is useful for lists copied from spreadsheets that may have blank rows.
- Document for transparency: For contests, take a screenshot of the input + output to prove fairness. The Fisher-Yates algorithm is mathematically provably fair.
- Re-shuffle for different results: Each click generates a new independent shuffle. The original input is preserved for multiple randomizations.
- Combine with Coin Flip: Use Coin Flip for binary decisions, List Randomizer for multi-item selection.
- Large lists: Works with 1000+ items. For very large lists, copy/paste may be slow; the shuffling itself remains instant.
- Use for weighted selection: Duplicate items in the input proportionally to their desired weights for pseudo-weighted randomization.
- Seed for reproducibility: For testing, note that Math.random() isn't seedable. For reproducible shuffles, use a programming library instead.

Event Organizers
Create tournament brackets, seating charts, and speaking orders without bias.
Educators
Randomize student groups, assignment order, or quiz question sequences.
Researchers
Randomize participant assignment to control/treatment groups in experiments and A/B tests.
Gaming Communities
Randomize draft order, map selection, or team composition for fair competitive play.
Frequently Asked Questions
Q: How does the list randomizer work?
A: The tool uses the Fisher-Yates shuffle algorithm to reorder your list items. Each item is swapped with a randomly chosen item from the remaining unshuffled portion, ensuring a truly uniform random distribution.
Q: Can I use this for team assignments?
A: Yes. Paste your list of names, one per line, and the randomizer will shuffle them into a random order. You can then pair adjacent names as teams or assign positions based on the randomized order.
Q: Does the original list change?
A: No. The original list in the input area remains unchanged. The randomized output is displayed separately, so you can re-shuffle multiple times without re-entering your data.
Q: How many items can I randomize?
A: There is no hard limit. The tool handles lists of 5 or 500 items equally well. Very large lists (1000+) may take slightly longer to process but will still complete quickly.Q: Is my data private?
A: Yes. All randomization happens locally in your browser. No list data is sent to any server. Your names, items, or any other data remain completely private.
Q: Can I randomize numbers instead of names?
A: Yes. You can paste any text-based list: names, numbers, items, tasks, or any other line-separated data. The tool shuffles lines regardless of their content.
Q: Is the shuffle truly random?
A: It uses JavaScript's Math.random() with Fisher-Yates algorithm, which is cryptographically sufficient for non-security purposes like contests, team assignments, and study schedules.Q: Can I get the same shuffle twice?
A: Each shuffle is independent. Getting the exact same order twice is mathematically possible but extremely unlikely for lists over 5 items.
Q: Can I use this for weighted random selection?
A: No. This tool gives equal probability to all items. For weighted selection, duplicate items in the input list proportionally to their weights.
Q: Does it work with duplicate items?
A: Yes. Duplicate items are treated as separate entries and will appear in the shuffled output according to their count in the input.
