Can the same number appear more than once in the list?

Yes, each value is drawn independently with replacement, so repeats are expected, especially with a small range and a large count.

What's the maximum count I can generate at once?

1,000 values per generation, which keeps the output readable and the computation instant.

How is this different from the plain Random Integer Generator?

That tool returns exactly one integer per draw; this one returns a whole list of them from a single count setting.

What happens if min equals max?

Every value in the list will be that same number, since it's the only whole number available in the range.

Random Integer Range Generator - Batch of Random Whole Numbers

Overview

Introduction

This tool generates a batch of random whole numbers within a min/max range you set, with each value drawn independently and listed one per line.

It's built for cases where you need several random integers at once rather than repeatedly regenerating a single value.

What Is Random Integer Range Generator?

A bulk version of a random integer draw: set a min, a max, and a count, and get that many independently sampled whole numbers back as a list.

Because sampling is with replacement, the same number can and often will appear more than once in the output, especially for small ranges.

How Random Integer Range Generator Works

Min and max are normalized to whole numbers with Math.ceil/Math.floor, then the tool loops count times, drawing a fresh uniformly random integer from that range on each iteration.

All values are independent of each other — there's no shuffling or without-replacement logic, matching how dice rolls or repeated coin flips behave.

When To Use Random Integer Range Generator

Use it to seed test data, build a quick list of sample row IDs, or simulate repeated random draws like dice rolls or lottery numbers.

If you specifically need each value to be unique, this tool won't guarantee that — you'd need to de-duplicate the output yourself or use a shuffle-based tool instead.

Often used alongside Random Integer Generator, Random Number Generator and Random Number Pair Generator.

Features

Advantages

Generates up to 1,000 values in one click instead of regenerating a single-value tool repeatedly.
Output is plain one-per-line text, easy to paste into a spreadsheet column or script.
Handles negative ranges and single-value ranges correctly.

Limitations

Not cryptographically secure — built on Math.random(), not suitable for security-sensitive randomness.
Does not guarantee unique values across the batch; duplicates are expected behavior, not a bug.

Examples

Ten dice-like rolls

Input

(no input; generated from settings: min 1, max 6, count 10)

Output

Ten independent draws from 1 through 6; note the repeated values, which is expected.

A five-item negative range batch

Input

(no input; generated from settings: min -5, max 5, count 5)

Output

Negative and positive integers are equally likely across the range.

Best Practices & Notes

Best Practices

Increase the count when you need statistical variety rather than clicking Regenerate on a single-value tool many times.
De-duplicate the output yourself downstream if uniqueness matters for your use case.

Developer Notes

Each value in the batch is generated by an independent call to the same min + Math.floor(Math.random() * (max - min + 1)) formula, so the batch has no memory of prior draws within it.

Random Integer Range Generator Use Cases

Simulating repeated dice rolls or lottery draws for a demo
Seeding a spreadsheet or database column with sample integer data
Generating a quick list of random delays or offsets for a script

Common Mistakes

Expecting the batch to contain no duplicates — sampling is with replacement by design.
Setting an extremely large count when only a handful of values are actually needed, making the output harder to scan.

Tips

Copy the output directly into a spreadsheet — each line lands in its own row.
Combine with a narrow range (like 1-2) to simulate repeated coin flips.
