How to Use Random Number Generator (Advanced)

What is Random Number Generator (Advanced)?

Random Number Generator (Advanced) produces random integers or floating-point numbers with full control over minimum and maximum range, output count, uniqueness constraints, decimal precision, and output format. Unlike basic random generators that produce a single value, this tool can generate thousands of values in a single operation, sort them, deduplicate them, or format them as JSON arrays and CSV data. The underlying randomness uses Math.random which is suitable for non-security purposes; use the Random Bytes Generator tool for cryptographic applications. It covers every practical use case for random number generation from lottery draws to bulk test data.

Features

How do I use Random Number Generator (Advanced)?

Set the minimum and maximum values defining your desired range, specify the count of random numbers to generate, and configure options including uniqueness (no repeats), decimal places for floating-point output, and sort order (ascending, descending, or unsorted). Click Generate to produce the values. Select your preferred output format from the format dropdown: one per line, comma-separated, space-separated, or JSON array. Copy the full result with one click for immediate use in code, spreadsheets, or test fixtures.
