According to me, Excel is better as it gives more control over range of data you will need to read, It also has ample scope to format data if you need.

But this is a very general opinion. You will have to decide based on what type of data you will read (numeric or string or large blobs etc),

what you will need to do with data. Will you write something in the file again etc.

thanks...my data contains both string at first row alone(header) and numeric. i have to do some calculation(+,-,\,*) with them and write again to a new excel file

I would go with Excel in this case. xlswrite, xlsread, Activex(For formatting and macros if you need) will be all you need. All the best!
