Spreadsheet website

[hedjr]

I want to create a website wherein visitors upload a simple excel spreadsheet file and my site displays a line chart with a linear trend line of that spreadsheet data for the visitor to download or copy. I can put together a suitable web page for this, but what else would I need (type of script, etc.) to do this in an automated fashion? Is there a package solution out there? Thanks!

Some advanced server side scripting is required

A job for a pro developer

I sugest looking into the google chart API if your technically savy

Much easier to intergrate into a web app
