UUID to Random Object Generator
Convert UUID strings into deterministic, structured JSON objects. Define schemas to generate realistic user profiles, game items, or test data from hashes.
About
This tool transforms universally unique identifiers (UUIDs) into rich, structured objects using deterministic algorithms. Unlike standard random generators which produce different results every time, this system uses the entropy already contained within the UUID string to drive the generation. If the input UUID is the same, the output object is mathematically guaranteed to be identical.
The core mechanism operates by slicing specific segments of the hexadecimal UUID and normalizing them into a scalar value S. This scalar is derived by dividing the integer value of the hex segment h by the maximum possible value for that segment length hmax. This creates a consistent seed ($0.0 \le S \le 1.0$) used to map values to integers, floats, arrays, or booleans.
Formulas
The normalization of a hexadecimal segment into a usable probability seed follows this high-precision ratio:
Where segment is the hexadecimal substring extracted from the UUID, and L is the length of that substring (number of characters). The denominator represents the maximum possible value for a hex string of length L (e.g., if L=2, max is 255 or FF).
