How to Insert Excel file into webpage
 

Hi
I have made some tax calculators and would like to know how to insert them
onto my website.
I have tried the frontpage route but the user will have to download "Excel
XP Web component" to be able to view it.

Is there any other method where the web user be able to see/use the
calculator without downloading any additional software for example like this
website http://listentotaxman.com which I believe he made in "mysql"
How can I achieve the same result by inserting my excel file in a website?



Thanks
