I am using Java technology
I have tried a sheet by downloading from our application.One thing I have observed that if I just try to read the file directly after downloading ,it is getting failed.But if I open the same file and and click on save icon of the Sheet ,and the try to read the file the I am able to read the sheet correctly.Don't know if the issue is with the sheet or with module.
I am using Streaming reader functionality.
