displaying data on an excel to a already designed web page ? i have no idea at all
Designed by what? Maybe something like (but has not been tested):
<iframe src = "YourExcel.xlsx" width="100%" height="100%"></iframe>
but you must have your Excel file in the same folder path as the HTML document.
Can you be more clear with your question? You can use php to read your excel spread sheet and display on to the html page, or you can upload to database and then output the contents.
