Application XML Node in "app.xml" is Empty for New Workbooks

Aspose.Cells Product Family
,
#1

Hello,

When a new Workbook is created and saved by Aspose Cells, the <Application> XML node within the app.xml file is always empty. The expectation is that the node be populated to identify the Application. For example, a new Workbook saved under Excel has the following value: <Application>**Microsoft Excel</Application>.

This behavior can be seen in the latest Aspose Words for Java version 21.3, and the following Java code:

Workbook workbook = new Workbook();
workbook.save(""AsposeDefault.xlsx");

If you open the new workbook in a ZIP viewer (such as 7-Zip) and examine the file \docProps\app.xml - you should see that the the Application node is empty: <Application />

We realize this is not a major issue. However, we rely on the the value from the <Application> node to identify the type of Office document. When it is not populated, we need to use other means for discovering the file type.

Thank you

@oraspose,

Please set Workbook.BuiltInDocumentProperties.NameOfApplication by yourself to fulfill your needs via Aspose.Cells API.

Thank you for your reply.

Apologies for reviving this old thread, but one of the reasons this issue was raised is because - we need a way to identify when a Workbook is saved under the Aspose Cells library. We typically read the <Application> node in app.xml for discovery purposes.

Also note that the Aspose Slides and Aspose Words libraries do populate the <Application> node in their corresponding app.xml files. We realize they are different libraries, but app.xml is a common within a XLSX, DOCX & PPTX file.
