How do I specify the XLS sheet name in the Surfer GridData automation command?

Use the GridData3 method, which includes the DataFileOptions parameter, to open a particular worksheet in an Excel file. The sheet specification is one of the DataFileOptions options.

 

SurferApp.GridData3("c:\temp\book1.xls",DataFileOptions:="sheet=Test", ShowReport:=True,OutGrid:="c:\temp\book1.grd")
