Excel to Web (HTML/Javascript)

[makingtrails]

I have a finance calculator that I wish to embed into a website. It works great using the new Embedded Web App in Excel 2013 using Skydrive but I would like to able to remove the "Excel Web App" Footer

However, this is not possible so have been looking at alternative ways to publish Spreadsheet online. Spreadsheet Converter has a HTML/Javascript converter but is too expensive. Does anyone know another method to publish functional Excel Spreadsheets to the web?

The frame includes elements that cannot be customized. The bottom bar cannot be removed, and, other than adding a Download button, its links cannot be modified.
