Usage Guide

  • 1. Paste a valid sample JSON object or API response into the input pane.
  • 2. Choose your target language (TypeScript, Go, Java, Python, Rust) from the top bar.
  • 3. Preview inferred strong type definitions and copy them into your project.

Security & Privacy Guarantee

  • 1. Empty arrays or null values in sample JSON may fallback to generic type definitions.
  • 2. Converting snake_case to camelCase may alter original JSON property names.
  • 3. Generates type definitions only; does not generate database ORM mapping code.

Frequently Asked Questions

Q: Does it support optional or nullable field inference?
A: Yes. The parser detects null values and automatically appends optional `?` markers or pointer types.
Q: Is it safe to parse JSON containing secret API keys or configs?
A: Safe and reliable. Type inference runs entirely inside the browser frontend JS engine; data is not reported or written to disk.
