Following is the code I have and in the final method below, I do all the operation. Please ignore the return types of methods, I have changed it later.
public static byte[] CreateExcelDocument<T>(List<T> list, string filename) { DataSet ds = new DataSet(); ds.Tables.Add(ListToDataTable(list)); byte[] byteArray = CreateExcelDocumentAsStream(ds, filename); return byteArray; } public static bool CreateExcelDocumentAsStream(DataSet ds, string filename, System.Web.HttpResponse Response) { try { System.IO.MemoryStream stream = new System.IO.MemoryStream(); using (SpreadsheetDocument document = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook, true)) { WriteExcelFile(ds, document); } stream.Flush(); stream.Position = 0; Response.ClearContent(); Response.Clear(); Response.Buffer = true; Response.Charset = ""; // NOTE: If you get an "HttpCacheability does not exist" error on the following line, make sure you have // manually added System.Web to this project's References.

Above is my code. I do try to add color by filling in stylesheet, however i dont understand the concept of styleindex to apply to a cell. Please help.

dmoore1181 over 2 yearsThis is extremely useful for getting started with OpenXML. I was able to use this as a good starting point, add a bunch of enums and get a proof of concept going quickly because of your answer. Thank you.
