Excel to Embed to Web (HTML/Javascript)

I have Office 365 which has a great feature to upload your Excel file to Skydrive and use the embed feature to have a fully function spreadsheet embedded into a website.

This works great however M$ have decided to brand the iframe with "Excel Web App" which doesn't look very professional on my website.

There is plugin which does this but it's pretty expensive.

Does anyone know any other software which can convert a functional excel spreadsheet to HTML/Javascript/php/HTML5 or have a function to embed like Skydrives?

Thanks
