Overview
Introduction
Randomizing the order of lines in a text file is a common need for shuffling playlists, quiz question banks, name lists, or CSV row order without touching the content of each line.
This tool splits on newline characters, shuffles the resulting array with Fisher-Yates, and rejoins with newlines, leaving each individual line's text completely unchanged.
What Is Text Line Shuffler?
A line-order randomizer for any newline-delimited text: to-do lists, name lists, CSV rows, playlists, or code snippets where line order doesn't matter semantically.
It treats every line — including blank ones — as an independent, movable unit.
How Text Line Shuffler Works
The input is split on `\n` into an array of lines (blank lines become empty-string entries).
Fisher-Yates shuffle reorders the array uniformly at random, and the lines are rejoined with `\n` to produce the output.
When To Use Text Line Shuffler
Use it to randomize the order names are called in a raffle or roll call, or to shuffle quiz questions so no two students see them in the same order.
Use it to randomize a playlist's track order or shuffle rows of tabular data before further processing.
Often used alongside Paragraph Shuffler, Text Column Shuffler and Word Shuffler.
Features
Advantages
- Preserves each line's exact text — only the order changes, nothing is altered, trimmed, or reformatted.
- Handles any number of lines, from a short list to a large file, in one pass.
- Uses an unbiased Fisher-Yates shuffle so every possible line order is equally likely.
Limitations
- Blank lines are shuffled like any other line, which can move gaps to unexpected places — strip them first if that's not desired.
- It only reorders whole lines; it doesn't shuffle content within a line (see the Word Shuffler or Text Column Shuffler for that).
Examples
Best Practices & Notes
Best Practices
- Remove trailing or accidental blank lines first if you want a clean, gap-free shuffled list.
- Use this before a raffle or roll-call to keep the process visibly unbiased.
Developer Notes
Splitting is done on a plain `\n`, so files using Windows-style `\r\n` line endings will keep a trailing `\r` on each shuffled line; normalize line endings first if that matters for your downstream use.
Text Line Shuffler Use Cases
- Shuffling names for a raffle or randomized roll call
- Randomizing quiz question order per student
- Shuffling playlist track order or list-based content
Common Mistakes
- Not noticing that blank lines count as shufflable items, resulting in gaps appearing in unexpected places.
- Expecting column-level shuffling — this tool only reorders whole lines.
Tips
- Trim your input to remove stray blank lines before shuffling if you want a tight list.
- Combine with the Random Item Picker if you only need one line chosen, not the whole list reordered.
