Displaying Excel xls files in web browser

[stualk]

Hi there,

 

I want to create a system where I can upload Excel files in xls format to my web server so that I can access them wherever I am and view/edit them? I've done this bit so far and everything is fine.

 

I'm having a problem with the second part of my system - I need other people to be able to VIEW these Excel files (only view, not edit) ideally as part of a web page rather than having to open the excel file in Excel. Some of my spreadsheets contain links to other spreadsheets/worksheets within some of the cells so ideally it needs to display this formatting as well if at all possible. Does anyone know of a way to do this using php?

 

Basically, it's the displaying of the excel documents i'm having difficulty with. I've done/know how to do the rest.
