Missing data while download from ALV to Excel

Hi Experts,

After a report is generated to ALV list, I'm trying to download the report into an Excel file.

Let's say there are 50 records, but in the Excel file only have 6 records, and the last record only have 1st 3 fields out of 14 containing the data and the rest is empty.

I'm using MS Excel 2010, and my system is 4.6C. Not sure what has really gone wrong.

Is there any solutions? Much appreciated for any suggestion and comments

Thanks.
