When Celll J10 contains an array formula and you try to copy it ABOVE the original row, Aspose creates a corrupt Excel file.
Cells cells = workbook.getWorksheets().get("Shearwater").getCells();
//Copy row above original row, makes Aspose 7.5.1.2 create corrupt excel file
cells.copyRow(cells, 9, 8);
cells.copyRow(cells, 9, 10);
Code for reproducing, input spreadsheet and result spreadsheet attached.
Aspose version 7.5.1.2
