  1. Introduced new property in class SpreadsheetLoadOptions

    /// <summary>
    /// Whether check restriction of excel file when user modify cells related objects.
    /// For example, excel does not allow inputting string value longer than 32K.
    /// When you input a value longer than 32K, if this property is true, you will get an Exception.
    /// If this property is false, we will accept your input string value as the cell's value so that later
    /// you can output the complete string value for other file formats such as CSV.
    /// However, if you have set such kind of value that is invalid for excel file format, you should not save
    /// the workbook as excel file format later. Otherwise there may be unexpected error for the generated excel file.
    /// </summary>
    public bool CheckExcelRestriction { get; set; }
