Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
You can return or set attributes either at the application (global) level or at the workbook level. (Note that attribute values can be different from one workbook to another, depending on the attribute value at the time the workbook was saved.) Workbook-level attribute settings override application-level attribute settings. Application-level attributes are contained in the DefaultWebOptions object.
Use the WebOptions property to return the WebOptions object.
