Is there a question?
I am unable to read data from the excelsheet in 97-2003 format. Please share the solution with me if you have.
Not easy. Your best bet is probably to convert it to another format (e.g. CSV). You could get the user to do that before upload, or you could use an online converter such as Google Docs to do it for them. If you have your own server, there are various server-side components that can handle xls.
