Some more VFP examples:

ox = CreateObject('excel.application')

ox.WorkBooks.Add()
ox.Visible = .t.
ox.ActiveWorkbook.Sheets.Add()
ox.Worksheets(1).Activate()

WITH ox.ActiveWorkbook.ActiveSheet
.Cells(1,1).Value = "My header"
.Cells(5,1).Value = 87
.Cells(5,4).Formula = "=B5*C5"
.Range("A1").Font.Size = 14
.Range("A1").Font.Bold = .T. && Title
.Rows(5).Font.Bold = .T.
.Columns(1).ColumnWidth = 30
ENDWITH

As Erik said, you can see the object model and properties in VBA Editor.
The easy way to get the a sample of use for some property reference - record a macro in Excel changing what you need visually, then Edit the recorded macro and see the code there.
