Export Excel to ImageSource in WPF

Besides converting a workbook to a different file format (like PDF, HTML, and image), GemBox.Spreadsheet also supports converting worksheets to ImageSource objects with the ExcelFile.ConvertToImageSource method.

If you require more than displaying a file's content, for instance if you want to be able to modify the spreadsheet data with some Graphical User Interface (GUI) control control, then what you could do is export Excel to DataTable and bind it to DataGrid control or you could export Excel to DataGridView control.

The following example shows how you can convert a sheet from an Excel file to an image and attach it to WPF's Image control.
