Create an XLSX from C#

Hi all,

I have looked in several places but many show show to create an .xls file but I'm looking on creating a .xlsx file (Microsoft Office Excel 2007).

I cannot use the OpenXML open source. It has to be Microsoft Office.

I didn't think the COM Interop would need to be used for .xlsx.

If that is the case how would it be done?

Any information and an example would be greatly appreciated.

Thanks

Hmmm...interesting. Is there another way using a COM or .NET reference for Excel that has these pieces and parts for the XML's or is it all XML based? Meaning there would be no COM or .NET object to use?

No, I don't want to export data. I want to create a file and add rows and columns to the file.

That's all. Right now, I have it in a comma delimited file but I want to see about making it more integrated and creating new sheets in the spreadsheet xlsx.

By the way, this is all using VS 2008 with .NET 3.5 (which that requires .NET 2.0)

But isn't COM for XLS? And not for XLSX? (obviously 2 different flavors MS).

Except that requires open source and I can't do that. The "using ICSharpCode.SharpZipLib.Zip;"

If I pursued that I would have to see about using it with like Winzip or the Windows Compression instead. Probably Winzip though because the Windows Compression is somewhat problematic.

Yeah, I saw that one previously as well. I wasn't too sure though. Because the nature of the ExcelPackage.

I have to look at that in a little more detail.

Thanks for the response and information. Turns out that using the XML's was really the only way. :-(

Thanks though and much appreciated.
