FAQ
Does shuffling alter my rows?
No. It only changes order and keeps the first row as a header.
How is the order randomized?
The tool uses the Fisher–Yates algorithm, which gives each ordering an equal chance.
Is my data uploaded?
No. It stays in the browser tab while you shuffle, copy, or download it.
