In the demo workplace there is an Excel export available in the Grid-export dialog. In own applications, the Excel export is missing...
Reason: the Excel-export is only available, if Apache-POI is part of the project. You may add by adding the following Maven-dependencies:
Code:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.16</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.16</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>3.16</version>
</dependency>
