OpenXML Excel program error

Question

I am getting the following error when I try to open the file. I just started testing this and I do not know what to do. So the code is very preliminary. The code for the class is attached. I only have about a year of C# experience and have not used OpenXML before and the lead programmer is hard to work for.

I want to be able to send a table (or change it to a list or class or something) to this class to make a xlsx spreadsheet. We want to eliminate the need for Excel. This is for health care field.

Thanks for any help I can get on this.

Replaced Part: /xl/worksheets/sheet.xml part with XML error. A document must contain exactly one root element. Line 1, column 0.

Here is the code that works. I had the row = new Row (); in the inner for loop and the rowCnt++; sd.Append(row); in the for loop also. It now works. Arep PS. I would like to close this out, but I do not see the option.

I have been working on this. I fixed the other problem above. The problem was by the first line. I was calling it multiple times to set the columns. columns.Append(CreateColumnData(1, ( UInt32 )dt.Columns.Count, 20)); But the only thing that works now is the columns width. It does open the spreadsheet,but except for the wider columns, nothing else is in the spreadsheet. The sheet name has changed also. Thanks for any help. Arep
