Setting SetIsBold method to true on a CellSelection, resets the font size of those cells to 11 points.
See the generated file of the attached program.

PS: Is it really necessary to have a support plan to report bugs?
Some of the leftmost borders are omitted when exported to PDF.

Workaround: Open the file with Excel and save it as a new document.
The data validation rule should have values for formula1 and formula2 elements, which define the start and end values for a range to validate between. When such values are missing, a NullReferenceException is thrown on import and the document cannot be imported.
When the worksheet contains many formulas which use large ranges (e.g. covering 50000 cells) as arguments and these formulas have to be calculated, this causes OutOfMemoryException.
When a chart is inserted in a document, generated by SpreadProcessing or WordsProcessing, the chart seems to lack any bars. The reason is that some theme information is missing, which effectively makes shapes take their default color, which is transparent. The same applies for shapes inserted in any Document Processing-generated OOXML documents - docx, xlsx. Workaround: (applicable for Excel) Manually change the theme for the document in MS Excel: - Choose Page Layout -> Themes -> Themes dropdown -> Office.
ArgumentException with clarification similar to "'\u001f', hexadecimal value 0x1F, is an invalid character." is thrown when trying to export document containing characters which are not supported in XML document - such as some control characters like 0x00, 0x1F, 0x1B, etc. Such characters are described in the XML specification here: https://www.w3.org/TR/xml/#charsets. Although the escaped strings are not supported (see https://feedback.telerik.com/Project/184/Feedback/Details/190228 ), the library could prevent the exception and export the document successfully by skipping such characters. Workaround: remove such characters before the export. Check the following StackOverflow answer for some ideas on code for replacing the characters: http://stackoverflow.com/a/14323524/259206 Fix available in R3 2018 SP1 release.
