FAQ
Can I get the same result every time?
Yes. Use an optional seed. The same input + same seed yields the same order.
Are blank lines removed?
It is configurable. When Exclude blank lines is ON, blank lines are omitted. When OFF, blank lines are shuffled as items.
How many lines can I shuffle?
It depends on device performance. In many cases, tens of thousands of lines are practical, but processing time and memory usage increase with size.
Can I keep the first line fixed as a header?
Yes. Turn on Keep first line fixed (header) to shuffle only from line 2 onward.
Is my data sent to a server?
No. Processing is done in your browser and input text is not sent to a server.
Is this fair enough for a draw?
Without a seed, each run produces a random order. If you need strict explainability, keep records of the original list, options, and seed handling.
