Hi Anatoly,
Thank you for using Syncfuion products.
XlsIO also provides various save options to control images and text in an Excel file. It enables you to save a worksheet with the displayed text or value in the cell to HTML file. The following code example illustrates this.
[C#]
HtmlSaveOptions options = new HtmlSaveOptions();
options.TextMode = HtmlSaveOptions.GetText.DisplayText;
options.ImagePath = @"..\..\Output\";
sheet.SaveAsHtml("Sample.html", options);
Please go through the following online documentation for the same.
