Code & Type Converters
Transform API payloads into strict TypeScript interfaces, Zod schemas, Go structs, and translate bash cURL commands into JavaScript fetch, Python requests, or Go clients instantly.
Category Tools (8)
Click any tool to launchJSON to TypeScript Interfaces
Instantly infer TypeScript interfaces from a JSON payload.
- #1Paste your JSON payload into the left editor.
- #2The engine infers arrays, nested objects, and primitives.
JSON to Zod Schema
Infer Zod validation schemas directly from JSON payloads.
- #1Paste your JSON payload into the left editor.
- #2Copy the corresponding Zod schema code from the right editor.
JSON to Go Struct
Convert JSON payloads into Go struct definitions with json tags.
- #1Paste your JSON payload into the left editor.
- #2Copy the generated Go structs with `json` tags from the right editor.
YAML to JSON / JSON to YAML Converter
Bidirectional YAML and JSON conversion with syntax validation.
- #1Pick 'YAML to JSON' or 'JSON to YAML', then paste your input into the left pane.
- #2The result updates live on the right; use 'Swap' to reverse the direction.
cURL to JavaScript Fetch
Translate bash cURL commands into JavaScript fetch() API calls.
- #1Paste a bash `curl` command into the input.
- #2Copy the generated `fetch()` snippet (JSON bodies are wrapped in JSON.stringify; review other body types).
cURL to Python Requests
Translate bash cURL commands into Python `requests` code.
- #1Paste a bash `curl` command.
- #2Copy the Python `requests` script.
cURL to Go HTTP Request
Translate bash cURL commands into Go `net/http` client code.
- #1Paste a bash `curl` command.
- #2Copy the Go HTTP request client code.
SVG to JSX Converter
Convert raw SVG markup into a React JSX component.
- #1Paste raw SVG markup into the left editor.
- #2Copy the React component code from the right editor.
How Code & Type Converters Runs in Browser Memory
Cross-language engineering requires frequently bridging raw JSON API payloads into strict type systems, and bash network invocations into idiomatic code. DevScratchpad Code & Type Converters automate this translation process client-side with zero latency, providing production-ready types and networking code.
Runtime Security & Isolation
Conversion algorithms parse Abstract Syntax Trees (ASTs) and JSON tokens entirely in Web Worker threads. JSON-to-TypeScript recurses through deeply nested structures to infer primitive types, union alternatives, and optional properties. cURL converters parse command-line arguments (flags, headers, raw bodies, and authentication headers) into standardized HTTP request models, generating idiomatic Fetch, Python Requests, or Go net/http implementations without server dependencies.
Recommended Usage Workflows
- 01.Paste an API JSON response into the converter to immediately generate TypeScript interfaces or Zod schemas.
- 02.Paste terminal cURL snippets from DevTools Network tab to generate production-ready Python or Fetch request code.
- 03.Convert YAML manifests to JSON and vice-versa with bidirectional synchronization.
- 04.Clean and transform SVG vector graphics into clean, JSX/TSX React components with inline props.
Key Engineering Advantages
- Instant type generation for TypeScript, Zod, and Go without boilerplate.
- Network command translation from cURL into modern fetch, Python, and Go.
- Bidirectional YAML ↔ JSON parsing with full syntax checking.
- Clean SVG-to-JSX conversion stripping unsafe XML attributes and formatting React props.
Frequently Asked Questions (Code Converters)
How accurate is the JSON to TypeScript converter?
The converter analyzes object shapes, array item types, nested models, and nullability to generate strictly typed interfaces with clean casing and exported types.
Can I convert complex cURL commands with cookies, headers, and form-data?
Yes. Our cURL parser handles multi-header authentication (-H), query params, Bearer tokens, JSON bodies (-d), and multipart form data.
Does the YAML converter handle multi-document YAML files?
The YAML engine supports standard YAML 1.2 syntax, document dividers, and maps cleanly to equivalent JSON structures.
Are private API keys or cURL authorization headers leaked?
Never. All string manipulation and AST conversion executes inside your local browser thread. Nothing is transmitted externally.
