The table styles are not imported correctly from HTML. The back color is not respected. The column width is incorrect. The font size is different.

Font is not in proper case- All the cases are in lower case

In excel, if you set word wrap to cell content, make the column wider and then autofit the column in which it is, the content will fit to a reasonable width, as seen in the image below.

When doing the same in SpreadProcessing, the result is always a narrow column:

            CellSelection cellSelection = sheet.Cells[0, 0];
            cellSelection.SetIsWrapped(true);

            ColumnSelection columnSelection = sheet.Columns[0];
            columnSelection.SetWidth(new ColumnWidth(100, true));
            columnSelection.AutoFitWidth();

Result:

Here are the same steps performed in WPF RadSpreadsheet, which uses RadSpreadProcessing for its engine:

Workaround: this is the missing part after the export:

We use the PDF viewer in an WPF project and see sometimes faulty pdfs in the telerik viewer. If I open the pdf file in acrobat it lloks fine. Do you know this problem ?

Attached you find the original file and a screenshot from PDF viewer. Other files are shown correct in the telerik viewer.

When creating a data bar conditional formatting with middle axis, a plain data bar with left axis is created instead. Using the following code:

var dataBarValueContext = new DataBarValueContext
{
    MaximumValue = new NumericValue(1),
    MinimumValue = new NumericValue(-1)
};
// Create the rule and set the desired formatting
var rule = new DataBarRule(dataBarValueContext)
{
    UseGradientFill = false,
    Direction = DataBarDirection.Context,
    FillColor = ThemableColor.FromColor(Colors.Green),
    NegativeFillColor = ThemableColor.FromColor(Colors.Red),
    ShowBarsOnly = true,
    AxisPosition = DataBarAxisPosition.Automatic
};

var conditionalFormat = new ConditionalFormatting(rule);

worksheet.Cells[0, 0, 1, 0].AddConditionalFormatting(conditionalFormat);
worksheet.Cells[0, 0].SetValue(0.5);
worksheet.Cells[1, 0].SetValue(-0.5);

The expected value is this:

The result value is instead:

Currently EULA requires Telerik assemblies to be protected against unauthorized redistribution, by following specific guidelines for the different types of technology:
- for WPF: https://docs.telerik.com/devtools/wpf/installation-and-deployment/deploying-telerik-ui/protecting-telerik-assembly
- for ASP.NET AJAX: https://docs.telerik.com/devtools/aspnet-ajax/deployment/protecting-the-telerik-asp.net-ajax-assembly
- for WinForms: https://docs.telerik.com/devtools/winforms/installation-deployment-and-distribution/redistributing-telerik-ui-for-winforms

When the guidelines for WinForms or AJAX are followed (namely the call to ValidatePassPhrase() is uncommented in AssemblyProtection.IsValid() method, the following license message is added to the generated documents:
"This document was generated by a copy of Telerik Document Processing licensed for use only by '<MyApp>'."

Workaround: Set the application name as resource in the Application.Current, using the following code:

new System.Windows.Application();
System.Windows.Application.Current.Resources.Add("Telerik.Windows.Controls.Key", "MyApp");
where 'MyApp' should be replaced with the actual application name. References to PresentationFramework and WindowsBase .NET Framework assemblies should be added in order for this approach to work.
