Frequently Asked Questions
Clear answers about using this tool and automating workflows with RunMacro.
Are the generated random numbers truly random?
The tool uses modern browser cryptographic pseudorandom number generators (PRNG) via the Web Crypto API, ensuring statistically uniform distribution with high entropy for simulations, games, and QA testing.
Can I generate unique numbers without any duplicates?
Yes. Check the 'No Duplicates (Unique Numbers)' box to ensure that every generated number in your bulk batch is mathematically unique within your defined minimum and maximum range.
How do I automate random number entry in desktop apps?
You can export the generated numbers as CSV or use RunMacro Desktop Automation to dynamically inject randomized numbers and random delay intervals directly into desktop software and web forms.
