When xlsx/docx document is imported, and its main story is with non-default name ('workbook. xml'/'document.xml'), e.g. workbook2.xml/document2.xml, NullReferenceException is thrown and the document is not imported.

Note: Such documents are usually produced after conversion from a template dotx/xlsm.

Hi there I have a pdf and whenever I try to Import the PDF file into PdfFormatProvider.Import method for flattening purposes, it throws null reference exception.

I have added a sample .net project with PDF added as source. You just need to run the project on your end. I am using version 2023.3.1106 of document processing library.

I am using ASP.NET 4.8 framework.

Thanks

InvalidCastException 'Unable to cast object of type 'EffectContainerElement' to type 'EffectListElement' is thrown on import.

As a workaround, you can either use the old version of the assemblies (R2 2022) or you can set ImportSettings.SkipShapes of the DocxFormatProvider to true.

A NullReferenceException is thrown when copying a sheet containing a chart with Marker whose FIll is null.

There is a workaround which should be applied before copying the sheet:

foreach (FloatingChartShape chart in wsPureCompTemplate.Charts)
{
    foreach (SeriesGroup seriesGroup in chart.Chart.SeriesGroups)
    {
        foreach (SeriesBase series in seriesGroup.Series)
        {
            LineSeries lineSeries = series as LineSeries;
            if (lineSeries != null && lineSeries.Marker != null && lineSeries.Marker.Fill == null)
            {
                lineSeries.Marker.Fill = new NoFill();
            }

            ScatterSeries scatterSeries = series as ScatterSeries;
            if (scatterSeries != null && scatterSeries.Marker != null && scatterSeries.Marker.Fill == null)
            {
                scatterSeries.Marker.Fill = new NoFill();
            }
        }
    }
}
