Hi Team,

Could you please help to check this issue? I have an Excel 2010, when i try to open it, it throws error: Error for ZipFile java.util.zip.ZipException: invalid block type.

Why it throws ZipFile error?

My open code is as below:
public Workbook getWorkBook(String excelPath) throws Exception{
try {
LoadOptions opt = new LoadOptions();
opt.setMemorySetting(MemorySetting.MEMORY_PREFERENCE);
Workbook wb = new Workbook(excelPath, opt);
return wb;
} catch(Exception ex) {
System.out.println(ex);
}
}

Hi Sissi,


Thank you for writing back.

I am afraid, it is hard to say what could have caused the said problem unless we replicate the scenario first on our end. Moreover, we have looked into our issue database to find occurrences of this error com.aspose.cells.CellsException: Error for ZipFile, and was unable to find any. Most probably the issue was never reported by any other users of Aspose.Cells APIs. We would request you to please share the problematic sample here so we could properly investigate the problem cause, and provide you with information in this regard.
