Code:

public void TestVisioBigExcel()
{
string[] files = Directory.GetFiles(@“C:\Temp\visio”, “*.vsdx”);
foreach(string file in files)
{
Diagram diagram = new Diagram(file, LoadFileFormat.VSDX);
int nFile = 1;
foreach(Aspose.Diagram.Page diagramPage in diagram.Pages)
{
foreach(Aspose.Diagram.Shape OLE_Shape in diagramPage.Shapes)
{
if(OLE_Shape.Type == Aspose.Diagram.TypeValue.Foreign)
{
if(OLE_Shape.ForeignData.ForeignType == ForeignType.Object)
{
Stream Ole_stream = new MemoryStream(OLE_Shape.ForeignData.ObjectData);
// Get format of the OLE file object
Aspose.Cells.FileFormatInfo info = Aspose.Cells.FileFormatUtil.DetectFileFormat(Ole_stream);
if(info.LoadFormat == Aspose.Cells.LoadFormat.Xlsx)
{
// Modify an OLE object
Workbook workbook = new Aspose.Cells.Workbook(new > MemoryStream(OLE_Shape.ForeignData.ObjectData));
workbook.BuiltInDocumentProperties.Clear();

                                    MemoryStream outStream = new MemoryStream();
                                    workbook.Save(outStream, Aspose.Cells.SaveFormat.Xlsx);

                                    OLE_Shape.ForeignData.ObjectData = outStream.ToArray();
                                    
                                    nFile++;
                                    // Save back an OLE object

                                }
                            }
                        }
                    }
                }


                // Save Visio diagram
                diagram.Save($"C:\\Temp\\visio\\out{DateTime.Now.ToString("yyyyMMddHHmmss")}.vsdx", SaveFileFormat.VSDX);

            }
