Calculation Details

The Text Line Shuffler randomly reorders all lines in the input text.

Algorithm:
1. Split input text into individual lines
2. Create an array of all lines
3. Shuffle the array using Fisher-Yates algorithm
4. Join shuffled lines back into text

Learn how to use the Text Line Shuffler calculator and its working principles

How to Use This Calculator

  1. Enter your text in the "Text to Shuffle" field, with each line separated by a newline character (press Enter after each line).
  2. Optional: Check the "Preserve original line count" box if you want to maintain the same number of lines in the output.
  3. Click the "Shuffle Lines" button to randomly reorder the lines in your text.
  4. The shuffled text will appear in the "Shuffled Output" field.
  5. Click "Reset" to clear all inputs and start over.

Working Principle

The Text Line Shuffler uses the Fisher-Yates algorithm (also known as the Knuth shuffle) to ensure a truly random shuffle of the lines. This algorithm goes through the array from the last element to the first, swapping each element with another randomly selected element that comes before it (including itself).

Use Cases

  • Randomizing paragraphs in text content for variety
  • Creating randomized quotes from a text source
  • Preparing randomized study material
  • Randomizing lines in poems or lyrics
  • Any situation where you need to reorder text lines randomly while maintaining their content
