Frequently Asked Questions
Questions about this tool? We have got answers.
Why are json tags in camelCase?
Go struct tags use the exact JSON key names to match input data precisely. This avoids deserialization failures from snake_case conversion.
How are number types determined?
Integer values map to int. Decimal values (like balance) map to float64. This avoids using float64 for all numbers.
Is my data sent to a server?
No. All conversion runs 100% inside your browser via a Web Worker.
Tool Changelog & Updates
v1.1.02026-06-12
- Fix: Fixed PascalCase field naming (isVip → IsVip, createTime → CreateTime) and JSON tags now use original camelCase keys instead of snake_case.
- Feature: Accurate number type mapping — integer values map to the language's native integer type, decimal values map to float/double.
- UX: Updated module descriptions, How-to guides, and FAQ sections with multi-language support.
- Fix: Fixed "Conversion complete" toast showing even when JSON parsing failed — now only shows success on actual completion, shows error message on failure.
