When importing an xlsx document with a comment that does not have an author, an exception is thrown "Sequence contains no matching element" Note that this is a different bug from the very similar SpreadProcessing: Exception "Sequence contains no matching element" thrown in files containing notes or comments (telerik.com)

When the line spacing of the paragraph is set to "at least" and the line spacing value is smaller than the font size, Word makes the actual value of the line spacing to be larger in order not to squish the lines. During export to HTML, Word skips the line spacing in such case, in order to preserve the same effect. WordsProcessing exports the line spacing, which causes the lines to become squished.

When the image passed to the GetAllTextFromImage() method doesn't have any text in it, a NullReferenceException is thrown. The expected behaviour should be to return a null or empty string.

The value of the TextBoxField is not visible until the field is clicked.

Workaround: Force content update:

foreach (var widget in textBoxField.Widgets)
{
    widget.RecalculateContent();
}

If the update still doesn't fix the issue, change the font prior to setting the value of the field:

foreach (var widget in textBoxField.Widgets)
{
    widget.TextProperties.Font = FontsRepository.Helvetica;
}
Another option could be to set the ViewersShouldRecalculateWidgetAppearances to true in order to force the viewers to update the appearance of the widgets.

RESOLVED: The issue is dismissed. The actual reason for the results is that FontsProvider implementation is missing. For accurately displaying the text the fonts used in the document need to be resolved correctly.

At the moment the only data that can be passed to FloatingChartShape is a CellRange to be parsed to a chart. Some clients would like to use the IChartData implementations: NumericChartData and StringChartData. We need a FloatingChartShape constructors like this:

public FloatingChartShape(Worksheet worksheet, CellIndex cellIndex, IChartData values, IChartData categories)

And others if necessary.

Release 2024.3.802 (2024 Q3)

When a format string of type: _ * # ##0_ ;_ * -# ##0_ ;_ * "-"??_ ;_ @_  is set through code and the culture settings of the machine are set so that the number grouping symbol is space, the resulting format string comes out incorrect on export: _,*,# ##0_,;_,*,-# ##0_,;_,*,"-"??_,;_,@_, 

This will happen every time the symbols in-between and after _ and * coincide with the number group separator.

After Excel introduced the dynamic array support, files produced with the older Excel versions have formulas that may be displayed with @ in some contexts. For example a file that had the following:

=SUM(IF(A1:A10=1, B1:B10, 0))

Will be displayed like so:

=SUM(IF(@A1:A10=1, B1:B10, 0))

This is done in order to preserve the behavior of the files created in older versions of Excel.

The files created by SpreadProcessing are also treated by Excel as if they are created by pre-dynamic array Excel. Please, introduce support for the new behavior.
