Problems with a SPFileStream

Hi Aspose



In my code I get an Excel file from Sharepoint in a SPFileStream (which inherits from Stream) and use workbook.Open(filestream) but get an exception:



Aspose.Cells.CellsException: This file’s format is not supported or you don’t specify a correct format.



I have tried using the .Open(Stream, FileFormatType) method but it produced the same result.



I have tried to save the file to a filestream and then open it but still no luck.



A small facet of this could be that the file is made in Excel 2007 and then saved in 2003 format. It contains some text, some colored cells, a few numbers, a autosum formula, and a pie chart based on the numbers. Nothing special.



Do you have any suggestions regarding my error? I was quite surprised to experience this error as the Words doc2pdf conversion worked like a charm (I’m loading the file in order to convert it).

Hi,

Thanks for considering Aspose.

Could you post your template excel file here, we will check it soon.

Thank you.

This file is added to a Sharepoint document library, adorned with meta data, and then opened as a stream with the SPFile.OpenBinaryStream().

Hi,

Well, I tested your file with the following code, opened it and put a value into a cell and save as the file. All works fine.

Sample code:

Workbook workbook = new Workbook();
workbook.Open(@"f:\test\Testof2003format.xls");
Worksheet ws = workbook.Worksheets[0];
ws.Cells["B1"].PutValue("Hello...");
workbook.Save("f:\\test\\out_Testof2003format.xls");

Which version of Aspose.Cells for .NET you are using. Could you try the attached version.

Thank you.
