How do you specify the file format as .xls and not .xlsx when saving an excel file in C# programatically?
I’ve tried using Excel.XlFileFormat.xlXMLSpreadsheet
Which enumeration type will save the spreadsheet as a 2000-2003 formatted excel spreadsheet?
From 2007/2010 automation you want
Excel.XlFileFormat.xlExcel8for a 2000-2003.xls.
