+## Extracting the data
+
+The simplest way to extract the data from the response is by using an [Expression](/nodes/math/expression/) node, and accessing the body from the response:
+
+<div className="ndl-image-with-background l">
+
+![](/library/prefabs/xano/extract-response.png)
+
+</div>
+
+For more advanced extraction (and parsing) you can use a [Function](/nodes/javascript/function) node.
