ExportActions.cs

workbook.LoadDocument("Documents\\ExpenseReport.xlsx");
workbook.Calculate();
Worksheet worksheet = workbook.Worksheets[0];

// Create an object containing HTML export options.
HtmlDocumentExporterOptions options = new HtmlDocumentExporterOptions();

// Set HTML-specific export options.
options.CssPropertiesExportType = DevExpress.XtraSpreadsheet.Export.Html.CssPropertiesExportType.Style;
options.Encoding = Encoding.UTF8;

// Specify the part of the document to be exported to HTML.
options.SheetIndex = worksheet.Index;
options.Range = "B11:O28";

// Export a document to an HTML file with the specified options.
workbook.ExportToHtml("OutputRange.html", options);

// Export the entire worksheet to a stream as HTML.
FileStream htmlStream = new FileStream("OutputWorksheet.html", FileMode.Create);
workbook.ExportToHtml(htmlStream, worksheet.Index);

ExportActions.vb

workbook.LoadDocument("Documents\ExpenseReport.xlsx")
workbook.Calculate()
Dim worksheet As Worksheet = workbook.Worksheets(0)

' Create an object containing HTML export options.
Dim options As New HtmlDocumentExporterOptions()

' Set HTML-specific export options.
options.CssPropertiesExportType = DevExpress.XtraSpreadsheet.Export.Html.CssPropertiesExportType.Style
options.Encoding = Encoding.UTF8

' Specify the part of the document to be exported to HTML.
options.SheetIndex = worksheet.Index
options.Range = "B11:O28"

' Export a document to an HTML file with the specified options.
workbook.ExportToHtml("OutputRange.html", options)

' Export the entire worksheet to a stream as HTML.
Dim htmlStream As New FileStream("OutputWorksheet.html", FileMode.Create)
workbook.ExportToHtml(htmlStream, worksheet.Index)
