## Overview

The Array Shuffle tool allows you to quickly randomize the order of elements in any list using professional-grade algorithms, ensuring fair and unpredictable results for your data.

## Inputs

- **Array Elements** (textarea): Enter array elements separated by delimiter... apple, banana, orange, grape, mango, peach, kiwi
- **Input Delimiter** (select)
- **Custom Delimiter** (text): Enter custom delimiter
- **Shuffle Algorithm** (select)
- **Number of Shuffles** (number): How many times to shuffle (1-10)
- **Random Seed** (number): Seed for reproducible results (optional)
- **Shuffle Mode** (select)
- **Output Format** (select)

## When to use

- Randomizing the order of names or items for fair selection processes.
- Creating randomized test datasets for software development and debugging.
- Shuffling sequences for games, simulations, or presentation slides.

## How it works

- Paste your list of items into the input field and select the appropriate delimiter.
- Choose a shuffle algorithm, such as Fisher-Yates, to determine the randomization logic.
- Apply optional settings like a random seed for reproducible results or specific shuffle modes.
- Select your preferred output format and generate the shuffled list instantly.

## Use cases

- Generating randomized participant lists for giveaways or lottery draws.
- Shuffling question banks for educational quizzes to prevent cheating.
- Randomizing task queues or test cases in automated software testing workflows.

## Frequently asked questions

### Can I get the same shuffle result twice?

Yes, by entering a specific number in the 'Random Seed' field, you can generate the same randomized output whenever you use that same seed.

### What is the difference between Fisher-Yates and other algorithms?

Fisher-Yates is the industry standard for unbiased shuffling, ensuring every possible permutation is equally likely.

### How do I handle custom separators?

Select 'Custom' in the Input Delimiter dropdown and enter your specific character, such as a pipe (|) or tab, in the Custom Delimiter field.

### Can I shuffle only part of my list?

Yes, use the 'Partial Shuffle' mode to randomize only a subset of your provided array elements.

### What output formats are supported?

You can export your results as a formatted table, JSON, CSV, or a simple text list.
