"excel to table" - how to specify Excel file address within the code

Question

I have recently found and implemented the code in "Reading An Excel File Using HTML 5 And jQuery" (excel to table) - and it really works great!

I would like to implement this method within the web page I am working on. In the original example - after running it, you have to click on the button and point to the Excel file you want to convert to table. 

Is there a way to change the code, where the Excel file address is hard-coded, without the need of using the button and specify it manually?

The original code ("Excel2Table.rar") is attached.

Thank you in advance tor the answer/suggestion!
