Developer utility

Convert JSON into production-ready code instantly

Paste JSON on the left, choose a target language on the right, and generate clean Go structs or TypeScript interfaces in real time. This page is designed with the same dual-panel workflow developers love in quicktype-style tools.

Clean output

Generate readable, nested code with proper field mappings.

Fast validation

Invalid JSON is handled gracefully with clear feedback.

One-click actions

Copy or download the generated code without leaving the page.

JSON Input

Paste any JSON payload and see the output update immediately.

Line-aware editor

Generated Output

Choose a target language, then copy or download the code.

Why developers use this JSON converter

This tool helps teams turn API responses into strongly typed code faster. It reduces manual boilerplate, keeps field names aligned with JSON payloads, and makes it easier to move between backend and frontend codebases.

How to use

  1. 1. Paste valid JSON into the editor on the left.
  2. 2. Switch between Go Struct and TypeScript Interface tabs.
  3. 3. Copy the generated code or download it as a file.
  4. 4. Fix any validation issues if the input JSON is malformed.

FAQ

Can this handle nested objects? Yes. Nested objects and arrays are converted recursively into nested Go structs and TypeScript interfaces.

Does it work offline? The conversion runs in the browser with no server round-trip, so the UI feels instant.

Is the output safe to paste into production code? The generated code is a strong starting point, but always review naming, optional fields, and type inference before shipping.
