Array of 100 random numbers
The 100-element random number array generator creates a 100-element array in seconds. Each element is a random number in a given range. Ideal for testing and populating databases.
100 elements in one array. Customize the range, exclude duplicates, choose output format. The array can be copied entirely.
Zero-knowledge architecture — the array is generated locally using a cryptographic API. Data is not transmitted to the server.
Features
- 100 elements in one array
- Formats: string, comma, tab, array
- Customizable number range
- Zero-knowledge: data never leaves your device
- Cryptographic API — true randomness
- Instant array copying
How it works

Frequently asked questions
About the array of 100 numbers
Why exactly 100 elements?
100 elements is the optimal size for testing most algorithms. Enough for a representative sample.
Can I change the number range?
Yes, you can set any minimum and maximum value from -999,999,999 to 999,999,999.
How do I copy the entire array?
Click the 'Copy all' button — the entire array will be copied to the clipboard in the selected format.
Are generated arrays saved?
No, the array only exists in the browser's memory. Data disappears when the page is closed.
