How does it work?

This tool randomly shuffles the order of lines in your text. Each time you click "Shuffle Lines", you'll get a different random arrangement. It's useful for:

• Randomizing the order of items in a list
• Creating random samples from a set of lines
• Generating random test data
• Randomizing quiz questions or flashcards

Example

First line
Second line
Third line
Fourth line
Fifth line

First line
Fourth line
Second line
Third line
Fifth line

Note: The shuffle is completely random, so there's a small chance that the output might look the same as the input (especially with few lines). Click "Shuffle Lines" again to get a different arrangement.

The algorithm: This tool uses the Fisher-Yates (also known as Knuth) shuffle algorithm, which is an unbiased way to shuffle a collection. Each possible arrangement of lines is equally likely to occur.

Use cases:

• Randomizing the order of quiz questions
• Creating random samples from a dataset
• Shuffling a list of tasks or items
• Generating random test data from existing patterns
• Creating randomized flashcards for studying
