+# How to extract embedded OLE files from an Excel workbook as streams?
+
+You can extract OLE objects in an Excel workbook as streams using XlsIO. The following example demonstrates how to retrieve embedded files from a worksheet.
+{% tabs %}  
+{% highlight c# tabtitle="C# [Cross-platform]" %}
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+    //Create worksheet
+    IApplication application = excelEngine.Excel;
+    application.DefaultVersion = ExcelVersion.Xlsx;
+    IWorkbook workbook = application.Workbooks.Create(1);
+    IWorksheet worksheet = workbook.Worksheets[0];
+
+    FileStream embedStream = new FileStream("../../../Sample.docx", FileMode.Open);
+    FileStream imageStream = new FileStream("../../../wordIcon.jpg", FileMode.Open);
+
+    //Create image stream
+    Image image = Image.FromStream(imageStream);
+
+    //Add ole object
+    IOleObject oleObject = worksheet.OleObjects.Add(embedStream, image, OleObjectType.WordDocument);
+
+    // Get the OLE part stream.
+    Image image1 = Image.FromStream(worksheet.OleObjects[0].GetEmbeddedOleStream());
+    MemoryStream memory = new MemoryStream(image1.ImageData);
+
+    //Saving the workbook as stream
+    FileStream stream = new FileStream("ExtractedFile.xlsx", FileMode.Create, FileAccess.Write);
+    memory.CopyTo(stream);
+    workbook.SaveAs(stream);
+    stream.Dispose();
+}
