Different Ways to Open Files

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 Workbook class constructor. Simply pass the path in the constructor as a string. Aspose.Cells will automatically detect the file format type.

Opening a File via 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.

Opening a File with Data only

To open a file with data only, use the LoadOptions and LoadFilter classes to set the related attribute and options of the classes for the template file to be loaded.

Loading Visible Sheets only

While loading a Workbook sometimes you may only need data in visible worksheets in a workbook. Aspose.Cells allows you to skip data in invisible worksheets while loading a workbook. To do this, create a custom function that inherits the LoadFilter class and pass its instance to LoadOptions.LoadFilter property.

Here is the implementation of the CustomnLoad class referenced in the above snippet.
