extendToNextSheet

Whether extends data to next sheet when the rows or columns of data exceed limit. Default is false.

extendToNextSheet : boolean;

Remarks

If this property is true, extra data will be put into next sheet behind current one (if current sheet is the last one, new sheet will be appended to current workbook). If this property is false, the data exceeding limit will be ignored.

headerRowsCount

Remarks

Those rows exceeding this limit will be ignored or extended to next sheet according to ExtendToNextSheet. This count includes the header rows(HeaderRowsCount). The maximum allowed value of it is the row limit of corresponding file format, such as for xlsx file it 1048576.
