    <p>Look into the OpenXML SDK: I understand that my example doesn't convert .csv files, but it will steer you in the right direction. <a href="http://msdn.microsoft.com/en-us/library/bb448854(office.14).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/bb448854(office.14).aspx</a></p> <p>I've used it in asp.net to create xlsx documents on the fly, streamed directly to the web client:</p> <pre><code>public static System.IO.MemoryStream ConvertToExcel(DataSet ds) { System.IO.MemoryStream stream = new System.IO.MemoryStream(); using (SpreadsheetDocument package = SpreadsheetDocument.Create(stream, SpreadsheetDocumentType.Workbook, true)) { package.AddWorkbookPart(); package.WorkbookPart.Workbook = new Workbook(); package.WorkbookPart.AddNewPart&lt;WorksheetPart&gt;(); if (ds.Tables.Count &gt; 0 &amp;&amp; ds.Tables[0].Rows.Count &gt; 0) { DataTable tbl = ds.Tables[0]; SheetData xlSheetData = new SheetData(); foreach (DataRow row in tbl.Rows) { Row xlRow = new Row(); foreach (DataColumn col in tbl.Columns) { object cellData = row[col]; Cell xlCell = null; if (cellData != null) { xlCell = new Cell(new InlineString(new DocumentFormat.OpenXml.Spreadsheet.Text(cellData.ToString()))) { DataType = CellValues.InlineString }; } else { xlCell = new Cell(new InlineString(new DocumentFormat.OpenXml.Spreadsheet.Text(String.Empty))) { DataType = CellValues.InlineString }; } xlRow.Append(xlCell); } xlSheetData.Append(xlRow); } package.WorkbookPart.WorksheetParts.First().Worksheet = new Worksheet(xlSheetData); package.WorkbookPart.WorksheetParts.First().Worksheet.Save(); // create the worksheet to workbook relation package.WorkbookPart.Workbook.AppendChild(new Sheets()); package.WorkbookPart.Workbook.GetFirstChild&lt;Sheets&gt;().AppendChild(new Sheet() { Id = package.WorkbookPart.GetIdOfPart(package.WorkbookPart.WorksheetParts.First()), SheetId = 1, Name = "Sheet1" }); package.WorkbookPart.Workbook.Save(); } } return stream; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
