I met an issue that Excel opens very slow (20+ minutes) after Cells.deleteColumns() and Workbook.save() while the original file can be opened in seconds. Code piece,
Workbook wb = new Workbook(“CF15386.xls”);
Worksheet ws = wb.getWorksheets().get(0);
ws.getCells().deleteColumns(1, 1, true);

Note: I’m testing under Windows 7 64/Excel 2010/Aspose Cells Java v 19.5.5.
