Get or Set the Class Identifier of the Embedded OLE Object

Possible Usage Scenarios

Aspose.Cells for Python via .NET provides the OleObject.class_identifier property which you can use to get or set the class identifier of embedded ole object. Ole Object Class Identifiers are actually GUIDs i.e Globally Unique Identifiers. GUID is always 16-bytes long, therefore Class Identifiers are also 16-bytes long. They are often found inside the Windows Registry and provide information to host application about how to open embedded ole object containing various embedded resources inside the client application.

Get or Set the Class Identifier of the Embedded OLE Object

The following screenshot shows the Ole Object Class Identifier i.e GUID which has been read from the sample excel file containing the embedded PowerPoint ole object.

Sample Code

Please see the following sample code executed with sample excel file and its console output which prints the Class Identifier of Ole Object i.e GUID. The printed GUID is exactly same as shown inside the screenshot.

from aspose.cells import Workbook
from uuid import uuid4

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Load your sample workbook which contains embedded PowerPoint ole object
wb = Workbook(dataDir + "sample.xls")
#  Access its first worksheet
ws = wb.worksheets[0]
#  Access first ole object inside the worksheet
oleObj = ws.ole_objects[0]
#  Convert 16-bytes array into GUID
guid = uuid4(oleObj.class_identifier)
#  Print the GUID
print(str(guid).upper())

Console Output

This is the console output of the above sample code when executed with the sample excel file.
