Random List Shuffler & Randomizer
Shuffle and randomize your lists instantly with cryptographically secure random ordering
[ List Randomizer - Quick Summary ]
What: List shuffler that randomly reorders any list of items using the Fisher-Yates shuffle algorithm with cryptographically secure randomization.
When to use: Shuffling names for drawings, randomizing presentation order, creating random playlists, distributing tasks randomly, or any scenario requiring unbiased list reordering.
Example: Input [Alice, Bob, Carol, Dave] → Shuffled [Carol, Dave, Alice, Bob]
Important: Uses Fisher-Yates algorithm for statistically perfect shuffling with zero bias. Supports all common separators (newlines, commas, semicolons, tabs). Works with Excel/CSV data.
Our list randomizer and list shuffler tool randomly reorders any list of items using the Fisher-Yates shuffle algorithm with cryptographically secure randomization. Randomize lists from text, Excel, CSV, or any format with support for multiple separators (newlines, commas, semicolons, pipes, tabs, spaces). Perfect for creating random orders, shuffling names, randomizing teams, drawing winners, picking random items, or any scenario requiring unbiased list randomization. Remove duplicates automatically, handle empty lines, and get instant results with true cryptographic randomness. Export randomized lists as text, CSV, or JSON. Completely free with no signup required.
What is a List Randomizer?
A list randomizer (also called a list shuffler) randomly reorders items in a list using cryptographically secure randomization. Unlike simple shuffles that may have predictable patterns, our tool uses the Fisher-Yates algorithm with PHP's random_int() for true cryptographic randomness.
Simply paste your list (from Excel, text files, or any source), choose your separator, and get an instantly randomized version. Perfect for random drawings, team assignments, playlist shuffling, or any situation requiring unbiased randomization.
List Randomizer Configuration Options
Multiple Separator Support
- Newlines/Line Breaks: Default for text lists, one item per line
- Commas (,): CSV format, Excel copy-paste
- Semicolons (;): European CSV format
- Pipes (|): Database exports
- Tabs: Spreadsheet data
- Spaces: Simple word lists
Duplicate Removal
Empty Line Handling

How to Randomize a List
[STEP 1] Enter Your List
Paste your list into the text area. Each item on a new line, or use commas/semicolons to separate items. Works with Excel copy-paste.
[STEP 1] Choose Separator (Optional)
Select how your items are separated. Auto-detection works for most cases, but you can manually specify newlines, commas, semicolons, or other separators.
[STEP 1] Randomize & Copy
Click "Randomize List" to shuffle. Your randomized list appears instantly. Copy individual items or export the entire list.
Common Use Cases for List Randomization
- › Random Drawings & Giveaways: Shuffle participant names to pick winners fairly
- › Team Selection: Randomize player order for team drafts or assignments
- › Presentation Order: Shuffle speaking order for presentations or interviews
- › Playlist Shuffling: Randomize music or video playlists
- › Task Assignment: Randomly distribute tasks among team members
- › Survey Randomization: Shuffle question or option order to reduce bias
List Randomizer Best Practices
- _ Use newlines (one item per line) for best compatibility
- _ Remove duplicates if you want each item to appear exactly once
- _ For large lists (1000+ items), consider splitting into smaller batches
- _ Double-check your separator matches your input format
- _ Save important lists before randomizing (export feature available)
Technical Implementation
Uses the Fisher-Yates shuffle algorithm with PHP's cryptographically secure random_int() function for statistically perfect random permutations with zero bias.
// Fisher-Yates shuffle with CSPRNG for ($i = count($items) - 1; $i > 0; $i--) { $j = random_int(0, $i); // Swap items[i] with items[j] $temp = $items[$i]; $items[$i] = $items[$j]; $items[$j] = $temp; } // Result: Uniformly random permutation
