GetFileExtension (String filePath)

Example

In this example, we are passing the required parameter to the function transformation object using a Variables object. We will be defining the file path of the file for which we want to extract the extension.

Where,

filePath = C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Files\GetFileExtension\GetFileExtension.docx

Right-click on the function transformation object and select Preview Output. As you can see, Astera Data Stack has returned the extracted file extension from the specified file path.
