About the CSV to shuffled CSV format

Each run produces a new order — re-transform to reshuffle.

Common use cases

  • Random samples
  • Shuffling quiz or test rows

How to use this tool

  1. Paste or upload CSV (and a second file when the tool needs it).
  2. Set options if shown, then click Transform.
  3. Copy or download the result.

Tips for best results

  • Shuffle is not cryptographic anonymity; pair with privacy tools when needed.
  • Preview before download and keep a copy of the original file.

Common pitfalls

Quoted commas and newlines must stay valid CSV — paste intact exports when possible.

Frequently asked questions

Is my CSV uploaded?
