| Purpose     | To return a string by reading a byte array in a specified encoding.                                                                                                                       |
| Description | Returns a string after it has been converted from a byte array.                                                                                                                           |

**Example**

In this example, we are passing the required parameters to the function transformation object using a *Variables* object and a *ToByte* object.

Where,

*bytes =* value

**Note:** The *Value* is the output value (bytes) from the *ToBytes* function transformation object, where a string value, “Hello World”, has been converted into a byte array.

*codepage* = 65001 (UTF-8 - Default)

Right-click on the *FromBytes* function transformation object and select *Preview Output.* You can see that Astera has returned a string value after successfully converting the provided byte array.
