Opening a File via a Path
Developers can open a Microsoft Excel file using its file path on the local computer by specifying it in the IWorkbook class constructor. Simply pass the path in the constructor as String. Aspose.Cells will automatically detect the file format type.
Opening a File using a Stream
It is also possible to open an Excel file as a stream. To do so, use an overloaded version of the constructor that takes the Stream object that contains the file.
