How to use the Random Sample Generator
- Put one complete choice on each line. Remove empty lines and check accidental duplicates.
- Choose the count or percentage and header-row support settings that fit your task.
- Select “Select sample” once. The result is created on this device.
- Review the selected items or shuffled list, then copy the result before changing the input.
What the Random Sample Generator does
Select a simple random sample from pasted rows by exact count or percentage.
The page gives you direct control over count or percentage, header-row support, no replacement, csv-friendly results. You can change the settings and make a fresh result without creating an account. Your entries and results stay in this browser unless you choose to copy or download them.
When this randomizer is useful
- Survey sampling. Use the random sample when you need a clear result for survey sampling. Set the rules first so everyone understands the draw.
- Spreadsheet checks. Use the random sample when you need a clear result for spreadsheet checks. Set the rules first so everyone understands the draw.
- Quality assurance. Use the random sample when you need a clear result for quality assurance. Set the rules first so everyone understands the draw.
How the result is chosen
The browser securely shuffles the available entries. Each position is chosen without using names, spelling, or the order in which you typed them.
Real Randomizer uses the secure random source built into modern browsers. The choice happens before any animation is shown. Visual effects make the result easy to follow, but they do not change it.
Tips for a clear and fair result
- Agree on the rules first. Choose the range, entries, filters, and repeat setting before anyone sees a result.
- Check the input. A duplicate name or missing item can change who or what has a chance to be selected.
- Run one accepted draw. Do not keep generating results only because the first answer was not popular.
- Save what matters. Copy the result or keep a simple record when the group may need to check it later.
Limits to keep in mind
A fair shuffle gives every entry a chance, but it cannot correct an incomplete or unfair source list.
Use this page for everyday choices, lessons, games, testing, and informal draws. Elections, regulated lotteries, health choices, legal decisions, and safety-critical work need approved systems and expert review.

Frequently asked questions
How does the Random Sample Generator work?
Select a simple random sample from pasted rows by exact count or percentage. The selection runs 100% locally in your browser using cryptographically secure random values (CSPRNG), so your results are mathematically fair and completely unbiased.
Can I share the generated results or page with friends?
Yes! You can copy the page link, share the tool directly across social media and messaging apps (WhatsApp, Telegram, X, Facebook, and more), or share a specific verified result outcome using the Share Result button.
How do I sample rows from a CSV or spreadsheet?
Paste your spreadsheet rows directly into the input box and check “First row is column header”. The tool will display your random sample in a clean formatted preview table with options to copy or download.
Can I sample by exact count or percentage?
Yes. You can choose an exact number of rows (e.g. 5 items) or a percentage of your total list (e.g. 25%). All draws are made without replacement so duplicate rows are never selected.
Are my entries or lists uploaded to a server?
No. Real Randomizer operates strictly on client-side browser cryptography. Your names, lists, tickets, and choices never leave your device.
Is the Random Sample Generator free to use?
Yes! All 50 randomizer tools on Real Randomizer are 100% free with no sign-up, no subscriptions, and no account required.
