Different processing time for different excel files


I am using aspose cell to extract data from excel files.

But some of the excel files took very long time to process (20mins), while most of them are processed just 1-2mins.

Any idea? Thanks.

Attached is the template file. Thanks.


Thanks for the sample file.

Please try our latest fixed version: v7.0.2.2, if it works fine as I have tested with following code, it takes a few seconds to complete the below process.

Workbook workbook = new Workbook(“e:\test2\20111028010135062%40upload.xls”);
