Object Generation Complete Guide
Master the art of generating complex object structures for testing, development, and data analysis
Object Generator creates arrays of objects with configurable key and value strategies. It helps teams test API contracts, UI tables, and business logic against realistic shapes without risking production data. You control how many objects to emit, how many keys each object contains, and whether keys are strings or numbers.
Value generation supports string, number, boolean, and mixed distributions. With a couple of dials, you can reproduce edge cases like extreme lengths, out‑of‑range numbers, or sparse objects—crucial for catching bugs early.
