Translate code between programming languages or frameworks. Includes parity checking to ensure equivalent functionality.
The Convert tool translates code between languages while maintaining equivalent functionality and following target language conventions:
Converts between 18+ programming languages, adapting syntax, idioms, and patterns to match the target language.
Converts between frameworks (e.g., React to Vue, Express to FastAPI) while preserving application logic.
Verifies that the converted code maintains functional equivalence and highlights any differences in behavior.
Produces code that follows the conventions and best practices of the target language, not just literal translations.
The Convert tool uses these context fields:
| Field | Description |
|---|---|
| Target Language | The language to convert to (required) |
| Target Framework | Optional framework for the target code (e.g., Vue, FastAPI) |
Click the Convert button (amber icon) or pressCmd/Ctrl + 5.
Enter the code you want to convert. The source language will be auto-detected or you can select it manually.
Choose the target language from the dropdown in the context section. Optionally specify a target framework.
Run the conversion. This uses high-quality models for accurate translation with deep language understanding.
Check the Result tab for the converted code and any notes about behavioral differences or required adjustments.
Converting a React component to Vue:
import { useState } from 'react';
interface Props {
initialCount?: number;
}
export function Counter({ initialCount = 0 }: Props) {
const [count, setCount] = useState(initialCount);
const increment = () => setCount(c => c + 1);
const decrement = () => setCount(c => c - 1);
const reset = () => setCount(initialCount);
return (
<div className="counter">
<h2>Count: {count}</h2>
<div className="buttons">
<button onClick={decrement}>-</button>
<button onClick={reset}>Reset</button>
<button onClick={increment}>+</button>
</div>
</div>
);
}Converted to Vue 3 Composition API:
<script setup lang="ts">
import { ref } from 'vue';
interface Props {
initialCount?: number;
}
const props = withDefaults(defineProps<Props>(), {
initialCount: 0,
});
const count = ref(props.initialCount);
const increment = () => count.value++;
const decrement = () => count.value--;
const reset = () => count.value = props.initialCount;
</script>
<template>
<div class="counter">
<h2>Count: {{ count }}</h2>
<div class="buttons">
<button @click="decrement">-</button>
<button @click="reset">Reset</button>
<button @click="increment">+</button>
</div>
</div>
</template>| From | To | Notes |
|---|---|---|
| JavaScript | TypeScript | Adds type annotations and interfaces |
| Python 2 | Python 3 | Updates syntax, print, unicode handling |
| React | Vue | Converts hooks to Composition API |
| Express.js | FastAPI | Python ASGI with type hints |
| jQuery | Vanilla JS | Modern DOM APIs |
| Java | Kotlin | Idiomatic Kotlin with null safety |
| CommonJS | ES Modules | Import/export syntax |
| Callbacks | Async/Await | Promise-based async |
Some conversions may have behavioral differences. The tool warns about:
Converting from dynamically typed (Python, JS) to statically typed languages (TypeScript, Go) may require type assertions or unions.
Different languages handle concurrency differently (goroutines vs async/await vs threads). The tool adapts patterns appropriately.
Language-specific libraries may not have direct equivalents. The tool suggests alternatives or provides manual implementations.
Manual Review Recommended
Always review converted code before using in production. While the tool maintains functional equivalence, edge cases in your specific use case may need adjustment.
