Shuffle a pasted list so every item appears exactly once in a random order.
Example
First, Second, an empty line, Third and Fourth give 4 items with 24 possible orders. Five items can be arranged in 120 ways and ten items in 3,628,800 ways.
Calculation method
Blank lines are removed, then items are drawn one by one without replacement using secure randomness, so every non-empty line appears exactly once and each possible order is equally likely.
Important notes
Identical lines are kept as separate entries, so A, A and B still return three items with A appearing twice. Remove duplicates first if each value should appear once. The list stays in your browser and is not uploaded.
Every item once, in a random order
Paste one item per line and shuffle. Every non-empty line appears exactly once in the result, and each possible order is equally likely because items are drawn one by one without replacement using secure randomness. Blank lines are removed first, so First, Second, an empty line, Third and Fourth give 4 items with 24 possible orders. This is useful for presentation order, reading lists, quiz questions, turn order in games and choosing who goes first without arguments.
How quickly the possibilities grow
The number of orders is the factorial of the number of items. Five items can be arranged in 120 ways and ten items in 3,628,800 ways. A standard 52-card deck has about 8.066 × 10^67 possible orders, so a properly shuffled deck is almost certainly in an order that has never existed before. Because each shuffle is independent, the same order can occasionally appear twice in a row for short lists, especially with only two or three items.
Duplicates and when to use other tools
Identical lines are kept as separate entries, so A, A and B still return three items with A appearing twice. Remove duplicates first if each value should appear once. To choose only a few items rather than reorder everything, the Random Name Picker is simpler, and to split a group into balanced teams use the Team Generator. The list stays in your browser. Shuffles are for everyday use, not for regulated draws that require documented, auditable procedures.

Frequently asked questions
How many orders are possible?
The factorial of the number of items. Five items give 120 orders, ten items give 3,628,800, and a standard 52-card deck has about 8.066 × 10^67 possible orders — which is why a properly shuffled deck is almost certainly in an order that has never existed before.
Why did I get the same order twice?
Because each shuffle is independent of the last. With short lists, especially two or three items, repeating an order is ordinary rather than a sign that the shuffle failed.
When is another tool a better fit?
To choose only a few items rather than reorder everything, the Random Name Picker is simpler, and to split a group into balanced teams use the Team Generator. Shuffles here are for everyday use, not for regulated draws that require documented, auditable procedures.
