Frequently Asked Questions

No. ToolZeno runs 100% client-side. The JSON parsing, structural extraction, interface mapping, and code generation processes occur entirely in memory within your browser. No data payload, files, or configs are transmitted over the network, ensuring absolute privacy for sensitive API models.

Our engine automatically performs a deep structural merge on array elements. If an array contains objects with differing schemas (e.g. some have a 'rating' key and others have 'isUpcoming'), it merges them into a single class or interface definition. Keys that are missing in some objects are automatically marked as optional or nullable in the generated output.

In Go, struct fields must start with a capital letter to be exported. Our Go generator automatically converts JSON keys to PascalCase for the Go struct field names, while preserving the original JSON key names inside the generated `json` struct tags.

Python dataclasses require fields with default values (such as Optional fields defaulted to None) to be declared after fields without default values. Our Python generator automatically partitions and sorts required fields first, preventing 'non-default argument follows default argument' runtime errors.

When literal union detection is enabled, the generator scans array items for recurring string or numeric constant values. If it identifies between 2 and 6 unique values (such as 'active' | 'inactive' | 'pending'), it outputs a TypeScript literal union type instead of a generic 'string' or 'number', giving you highly accurate type definitions.
