The format applied to the first value of the range of the chart determines the format of the value (vertical) axis. If the format of this value is changed, the model attempts to set a new format to the axis. If the chart does not support axes, the value of its PrimaryAxes property is null, which causes NullReferenceException.

Hello,

An exception is thrown when importing an xlsx file which has a comment that does not have an author. But the author may be null.

System.ArgumentException: 'author'

This exception was originally thrown at this call stack:
    Telerik.Windows.Documents.Spreadsheet.Utilities.Guard.ThrowExceptionIfNullOrEmpty(string, string)
    Telerik.Windows.Documents.Spreadsheet.Model.NoteCollection.Add(Telerik.Windows.Documents.Spreadsheet.Model.CellIndex, Telerik.Windows.Documents.Spreadsheet.Model.CellIndex, string, string)

    ...
    [Call Stack Truncated]

This is the code that can be used to reproduce the issue, according to your documentation:

        Workbook workbook;
        XlsxFormatProvider formatProvider = new XlsxFormatProvider();

        using (Stream input = new FileStream(_path, FileMode.Open))
        {
            workbook = formatProvider.Import(input);
        }

I have attached a document that got a comment without an author.

The attribute is lost when importing a document. This might lead to corrupting the macros.

In newer versions of EXCEL (2019 and later) the CONCAT function is introduced as a replacement of the old CONCATENATE function. It adds the ability to specify a range of cells when generating the resulting string in addition to its previously supported input arguments.
NOTE: In EXCEL starting from version 2019, CONCATENATE can no longer be inserted in the worksheet through the UI, it can only be used if you type it directly in the cell's contents.

A feature in Excel allows adding ActiveX controls in the Worksheets. You can insert the ActiveX controls from the Developer ribbon tab from the insert button. As it is a missing feature it is not imported and thus removed from the document on export.
