Random Sampler
Pick a random sample from a list.
Take a fair random sample
This selects a random subset of the size you choose from a pasted list, without replacement, so each item can appear at most once — useful for QA spot-checks and unbiased sampling.
It is how you pull a fair QA sample from thousands of rows, or draw names for a giveaway, without bias toward whatever happens to sit at the top of the list.
Fresh each run
Every run draws a new sample. The selection is generated in your browser, so the source list never leaves your device. Your list stays on your device and is never uploaded.
Frequently asked questions
What does this random sampler do?
Take a random sample from pasted rows by count or percentage.
How are rows chosen?
Every row gets a random number, the list is sorted by it, and the first N rows are taken, so every row has an equal chance and none repeats.
How does percent mode round?
Up. 10% of 25 rows returns 3 rows, so you never get an empty sample from a small list.
Will I get the same sample twice?
No. The sample is redrawn every time the input changes, and there is no seed. Copy the output as soon as you have a sample you want to keep.
