# Adding Data to Data Extension Object

Add more data to an existing data extension object when you add new records to your data extension.

## Usage

This code example contains a SOAP envelope that you can use to add data to an existing data extension.

```xml
<soap:Envelope
  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
