I have been using MemoryStrean stream = workbook.SaveToStream(), but now I am streaming to either PDF or Excel memory stream based on the passed in parameter, so now I have switched to
MemoryStream stream = new MemeoryStream();
workbook.Save(stream, isPDF ? FileFormatType.Pdf : FileFormatType.Default)
I looked up the documentation on Save(Stream, FileFormatType) and FileFormatType.Default stands for Excel2003. Is it the same format that my prior workbook.SaveToStream was using? I actually need to be backwards compatible with even older versions of Excel, so will probably need toswitch to FileFormatType.Excel2000, but before I do I'd like to know what format I was using before with the SaveToStream method, as so far noone has complained, although the number we have, so far, had mostly internal users who have Excel2003 or later, but we stream data out to a browser, so external users very well may have older versions of Excel or perhaps even OpenOffice spreadsheet or other, non-microsoft spreadsheets, and that is why I'd like to stick to older, simpler (more compatible?) file versions
