Set Default Font while rendering spreadsheet to HTML

Aspose.Cells allows you to set default font while rendering spreadsheet to HTML. Please use the HtmlSaveOptions.DefaultFontName for this purpose. This property is useful when there are some cells in a spreadsheet that have invalid or non-existing fonts. Then those cells will be rendered in a font specified with the HtmlSaveOptions.DefaultFontName property.

Set Default Font while rendering spreadsheet to HTML

The following sample code creates a workbook and adds some text in cell B4 of the first worksheet and sets its font to some unknown/non-existing font. Then it saves the workbook in HTML by setting different default font names like Courier New, Arial, Times New Roman, etc.

The screenshot shows the effect of setting different default font names via HtmlSaveOptions.DefaultFontName property.

The code generates the output HTML file with Courier New, the output HTML with Arial, and the output HTML file with Times New Roman.

Sample Code

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            
// Create workbook object and access first worksheet.
Workbook wb = new Workbook();
Worksheet ws = wb.Worksheets[0];

// Access cell B4 and add some text inside it.
Cell cell = ws.Cells["B4"];
cell.PutValue("This text has some unknown or invalid font which does not exist.");

// Set the font of cell B4 which is unknown.
Style st = cell.GetStyle();
st.Font.Name = "UnknownNotExist";
st.Font.Size = 20;
cell.SetStyle(st);

// Now save the workbook in html format and set the default font to Courier New.
HtmlSaveOptions opts = new HtmlSaveOptions();
opts.DefaultFontName = "Courier New";
wb.Save(dataDir + "out_courier_new_out.htm", opts);

// Now save the workbook in html format once again but set the default font to Arial.
opts.DefaultFontName = "Arial";
wb.Save(dataDir + "out_arial_out.htm", opts);

// Now save the workbook in html format once again but set the default font to Times New Roman.
opts.DefaultFontName = "Times New Roman";
wb.Save(dataDir + "times_new_roman_out.htm", opts);
