Shuffle Lines Randomly

The Randomize Text Lines Tool shuffles the order of lines using the Fisher-Yates algorithm for true randomness. Perfect for randomizing lists, shuffling CSV data, creating fair presentation orders, or generating random playlists.

Common Use Cases

Randomize Lists

Shuffle todo items, names, questions, or any line-based list for random ordering.

CSV Data Sampling

Randomize CSV rows for fair sampling, train/test splits, or data anonymization.

Fair Presentation

Eliminate position bias by randomizing order in surveys, tests, or presentations.

Frequently Asked Questions

How does line randomization work?

The tool treats each line as a separate item and uses the Fisher-Yates shuffle algorithm to randomly rearrange them. Each line maintains its content exactly - only the order changes. Empty lines are preserved and shuffled along with non-empty ones.

Can I shuffle CSV files?

Yes! Upload your .csv file and the tool will randomize the rows. This is perfect for creating random data samples, shuffling datasets before splitting into train/test sets, or anonymizing data order for privacy.

Are empty lines removed?

No. Empty lines are preserved and shuffled along with non-empty lines. If you want to remove them first, you can use a text editor to filter them out before shuffling.

Will I get the same shuffle every time?

No! Each shuffle is completely random. The Fisher-Yates algorithm ensures true randomness - you'll get a different order every time, even with the same input.

Can I use this for playlists?

Absolutely! Paste your playlist (one song per line), shuffle, and you've got a randomized order. Great for creating varied listening experiences from the same set of songs.

How does this help with fair ordering?

When presenting items (names for presentations, questions in surveys, products in tests), random ordering eliminates position bias. The first item doesn't always appear first, ensuring fair treatment for all items.

Can I upload log files?

Yes! The tool accepts .log files. Randomizing log entries can be useful for privacy (obscuring temporal patterns), testing (ensuring parsers don't rely on chronological order), or creating synthetic test logs.

Does this work with numbered lists?

Yes, but the numbers won't be updated. If you have '1. First' and '2. Second', after shuffling you might get '2. Second' then '1. First'. The line content stays exactly as-is.

Can I download the shuffled result?

Yes! Click the TXT button to download your randomized lines as a plain text file. The filename includes a timestamp for easy organization of multiple shuffled versions.

Is my data private?

100% yes. All processing happens locally in your browser using JavaScript. Your data never leaves your device, and nothing is sent to our servers. Completely private and secure.
