Random Number in Range Generator

How to use

1. 1️⃣
   Choose your options above
2. 2️⃣
   Click Generate
3. 3️⃣
   Copy your result

Detailed instructions

1. Enter your lower bound in the Minimum field and your upper bound in the Maximum field.
2. Set Count to the total quantity of numbers you want the generator to produce.
3. Adjust Decimal places to 0 for whole integers or higher for fractional precision.
4. Switch Unique only to Yes if you need every number in the output to be distinct.
5. Click Generate, then copy the results directly into your spreadsheet, code, or document.

Use Cases

• •Running a no-duplicate prize draw for 50 raffle ticket numbers between 1 and 500
• •Generating 20 random floats between 0 and 1 as probability weights for a Jupyter notebook
• •Seeding a Jest fixture file with unique random integers across a valid database ID range
• •Simulating D20 dice rolls in bulk for a tabletop RPG encounter tracker
• •Producing random sensor voltage readings between two thresholds to stress-test a data pipeline

Tips

• →For lottery draws, set Unique to Yes and keep Count well below your max to ensure the draw feels fair and unpredictable.
• →When generating decimal values for probability models, use 4 decimal places — more precision rarely adds value and makes outputs harder to read.
• →If you need a random sample from a dataset, generate unique row indices between 1 and your total row count instead of sampling the data directly.
• →Negative ranges work perfectly for simulating temperatures, financial deltas, or coordinate offsets — just type a minus sign before your minimum value.
• →Paste the output column into Excel or Google Sheets and use SORT() to rank the numbers if you need an ordered random sample.
• →Re-clicking Generate with identical settings produces a fresh set each time, so iterate quickly when you need to find a distribution that looks right for your use case.
