Is Workbook.FileFormat available to the Excel UI (specifically when the file type can't be saved)
How can I save my excel spreadsheet in DBF format? I used to be able to do this directly from excel, but they seem to have disabled this in the 2010 version.
I'd rather not install a whole new office suite to do this (e.g. open office, not withstanding its awesomeness) but would be happy to use a free, small utility or excel add-on if it is available.
