JSON to GraphQL Schema Converter Specification
Overview
A high-performance, single-file browser application designed to help software engineers convert raw JSON data samples into valid GraphQL Schema Definition Language (SDL) types. The application focuses on accurate type inference, recursive structure analysis, and developer-centric workflows.
Core Features
- Live Type Inference: Real-time conversion as the user types or pastes JSON data.
- Recursive Mapping: Automatically detects nested objects and defines corresponding GraphQL types.
- Error Handling: Visual indicator for invalid JSON syntax with descriptive error messages in a custom UI modal.
- One-Click Clipboard: Easy "Copy to Clipboard" functionality with visual success feedback.
- Format Toggle: Options to customize the output (e.g., strict vs. optional fields, naming conventions).
UI Layout Design
- Header: Clean, centered title with a descriptive tagline.
- Main Tool Area: A split-pane layout for desktop (Left: Input JSON, Right: Output GraphQL) that stacks vertically on mobile devices.
- Input Pane: A high-quality monospaced editor area (using
textareawith consistent styling). - Output Pane: Read-only syntax-highlighted code block area.
- Actions: A central toolbar containing "Convert", "Clear", and "Copy to Clipboard" buttons. Ensure primary actions use a clean, professional blue (
#2563eb) with rounded corners.
Aesthetics & Styling
- Palette: Light-mode focused.
- Background:
#f8fafc(Slate-50) - Cards:
#ffffff(White) with soft shadow (shadow-md) - Primary:
#2563eb(Blue) - Success:
#16a34a(Green) - Error/Warning:
#dc2626(Red) - Typography: Sans-serif (system-ui) for UI, Monospaced (Courier/Consolas) for code.
- Background:
- Transitions: Use
transition-all duration-200 ease-in-outfor all button interactions and state changes.
Developer Directives (CRITICAL)
- Zero Persistence: Do NOT use
localStorage,sessionStorage, or cookies. The tool must be "stateless" regarding user data. - Vanilla Implementation: No build steps. Use single-file
<script>and<style>blocks. CDN links (e.g., Prism.js for syntax highlighting) are permitted. - Sandboxed Compatibility: Assume the app lives in a restricted iframe. Do not use
alert(),confirm(), orprompt(). Create a customdiv-based overlay modal for notifications. - Performance: Ensure the type-inference loop is optimized for large JSON payloads to prevent UI blocking.
- Mobile First: Ensure the textareas are touch-friendly and the layout adapts to narrow screens by changing the flex-direction from row to column.

Frequently Asked Questions
Everything you need to know about using this application.
How does this JSON to GraphQL converter work?
This tool analyzes the structure of your provided JSON object, recursively traverses all key-value pairs, and maps them to standard GraphQL scalar types such as String, Int, Float, Boolean, and ID.
Is my data sent to a server for processing?
No. This tool operates entirely within your browser environment using client-side JavaScript. Your data is never uploaded, stored, or processed by an external server, ensuring complete privacy.
Does this tool handle nested JSON objects and arrays?
Yes. It supports deep recursive inference. Nested objects are automatically converted into custom GraphQL Object types, and arrays are wrapped in list brackets (e.g., [Type]) to reflect the proper schema structure.
