# Convert an ArrayBuffer to a string

Bun implements the Web-standard [`TextDecoder`](https://developer.mozilla.org/en-US/docs/Web/API/TextDecoder) class for converting between binary data types and strings.

```ts theme={null}
const buf = new ArrayBuffer(64);
const decoder = new TextDecoder();
const str = decoder.decode(buf);
```
