At this point, the justify alignment is not supported. Provide the ability to export text with this setting.

This feature is currently supported only for .NET Framework and WPF .NET Core for Windows assemblies.

I need to print a series of docx and pdf documents automatically to a printer from a web page directly on the server-side.

Implement options for setting hyperlink on an image and preserving it in import/export.

Introduce an option to replace a Run text with line breaks and/or new lines or with other document elements such as Table, Image, Paragraph and etc. 

The following code snippet shows how a Run can be replaced with another inline element:

RadFlowDocument document = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
 
editor.InsertText("text");
editor.InsertText("REMOVE");
editor.InsertText("text");
 
foreach (Run run in document.EnumerateChildrenOfType<Run>().ToList())
{
    if (run.Text == "REMOVE")
    {
        Paragraph paragraph = run.Paragraph;
        int childIndex = paragraph.Inlines.IndexOf(run);
 
        ImageInline image = new ImageInline(document);
        using (Stream stream = File.OpenRead("example_image.png"))
        {
            image.Image.ImageSource = new Telerik.Windows.Documents.Media.ImageSource(stream, "png");
        }
 
        paragraph.Inlines.Insert(childIndex, image);
        paragraph.Inlines.Remove(run);
    }
}

At this point, the import logic cannot automatically repair such documents and a NullReferenceException is thrown while reading them. You could repair the invalid file using the project from the attachment.

Add support for Excel 5.0/95 Workbooks.

From the OOXML Specification: A comment is a rich text note that is attached to and associated with a cell, separate from other cell content.

Add Mail Merge events.

Currently adding an Image content element with ImageSource instantiated with a PNG file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Support for adding PNG images and exporting to PDF should be implemented for PdfProcessing for .NET Standard scenario.

Add support for import and export of floating tables.

Handle the case where "Pages" is used in an actual page. This works in Adobe.

Provide support for exporting type3 fonts

Type 3 fonts are currently not supported.

Currently, importing a document with non-embedded TrueType font will result in a font instance with an empty font source. Support should be added for providing custom font data of TrueType fonts during document import.

When a csv is exported the entire range which has values is exported. When export is done in Excel, the cells of this range which are empty are marked by an additional field, separated by a comma. This comma is present in SpreadProcessing only in places where it is obligatory for example in the middle of the row. Obligatory comma in this context means that without it the file will not be read correctly by Excel or SpreadProcessing. In places where it is not obligatory, like in an empty row or in the end of the row, it is skipped. These non-obligatory commas do not influence how the file will be interpreted by Excel, however, according to the most-popular csv spec, they should be present, which means that there could be parsers which are unable to parse the resulting file. (2.4 Each line should contain the same number of fields throughout the file.) 

Example:
Exported by Excel:
---------------------------------------
Product,Unit Price,Units in Stock,Discontinued
Chai,$18.00 ,39,
Chang,,17,
Chef Anton's Cajun Seasoning,$22.00 ,53,No
,,,
Chef Anton's Gumbo Mix,$21.35 ,0,No
---------------------------------------
Exported by SpreadProcessing:
---------------------------------------
Product,Unit Price,Units in Stock,Discontinued
Chai,$18.00 ,39
Chang,,17
Chef Anton's Cajun Seasoning,$22.00 ,53,No

Chef Anton's Gumbo Mix,$21.35 ,0,No
---------------------------------------
Note the extra commas in the empty row and in the end of the first two rows in the SpreadProcessing sample.

According to the OOXML specification the shading color can be defined only in RRGGBB hex color, but MS Word also supports colors defined with their names - e.g. "Red".

Enable the customers to work with .dot files.

Enable the customers to work with .doc files.

The API should allow you to perform a text-based search and return the parent element(s) of the result(s) or directly the found element(s).
