Use the OleFormat property to access the data of an OLE object. You do not create instances of the OleFormat class directly.

Shows how to extract embedded OLE objects into files.
Document doc = new Document(MyDir + "Shape.Ole.Spreadsheet.docm");

// The first shape will contain an OLE object
Shape shape = (Shape)doc.GetChild(NodeType.Shape, 0, true);

// This object is a Microsoft Excel spreadsheet
OleFormat oleFormat = shape.OleFormat;
Assert.AreEqual("Excel.Sheet.12", oleFormat.ProgId);

// Our object is neither auto updating nor locked from updates
Assert.AreEqual(false, oleFormat.IsLocked);

// If we want to extract the OLE object by saving it into our local file system, this property can tell us the relevant file extension
Assert.AreEqual(".xlsx", oleFormat.SuggestedExtension);

// We can save it via a stream
using (FileStream fs = new FileStream(ArtifactsDir + "OLE spreadsheet extracted via stream" + oleFormat.SuggestedExtension, FileMode.Create))

// We can also save it directly to a file
oleFormat.Save(ArtifactsDir + "OLE spreadsheet saved directly" + oleFormat.SuggestedExtension);
