Question : Converting xcel files to html

I have on my website a place were members can login and upload a excel file..

I have on my website also this excel file converted to an html file, so that anyone can see it.

My question is:
Is there a way to convert the excel file that a person  downloads,  to an html file at the time they download the xls file. Automatically?
