Random List Picker
Random List Picker splits comma-separated or line-separated input, trims blank space, removes empty entries, and chooses one remaining position. Repeated entries remain repeated, so a name listed twice has twice as many eligible positions. It is useful for informal choices but offers no seed, immutable participant list, public record, or certified drawing procedure.
Runs locally — files stay on your deviceDoes a duplicate list item change its chance of being picked?
Yes. Each list position is eligible, so duplicate entries increase that value's chance.
Uniform position selection requires one intended entry per position
With N cleaned list positions, each position is intended to have probability 1/N. Equality between unique names only holds when each name appears exactly once.
How it works
Paste one item per line or separate items with commas. Review the cleaned list for duplicates and omissions, agree on eligibility, then run one selection.
Key concepts
Positions, not unique text, are sampled
Two identical lines are two tickets.
Fairness includes list governance
Random selection cannot fix an incomplete, altered, or disputed eligibility list.
When to use it
- Choose an informal participant or option.
- Pick one prompt from a short list.
- Sample one test item from pasted values.
When not to use it
- Do not use it for regulated prizes or legal allocation.
- Do not include secret or sensitive participant data unnecessarily.
- Do not ignore duplicate names or alternative spellings.
Worked examples
Four unique names
- Input
A, B, C, D- Expected output
One name
Each has one of four positions.
Duplicate entry
- Input
A, A, B- Expected output
A has two of three positions
Duplicates act as extra weight.
Blank lines
- Input
A, blank, B- Expected output
A or B
Empty entries are removed.
Common mistakes
Leaving accidental duplicates
Selection probability changes. Correction: Deduplicate when every participant should have one entry.
Editing the list after seeing a result
The procedure becomes contestable. Correction: Freeze and review eligibility first.
Using an informal picker for a regulated prize
The page lacks audit and compliance controls. Correction: Use a governed drawing process.
Best practices
- Review the cleaned list before drawing.
- Define whether duplicates are weights or mistakes.
- Record the final list and result externally when needed.
