Microsoft Excel is a desktop application but the company now offers a limited web edition which can be used for innovative purposes.
This is something that we have come to expect from Google through their Google Docs platform.
But Microsoft has launched a new project named ExcelMashup.com which highlights the capabilities of their online services.
The company spoke about this service:
The ExcelMashup.com web site is a one-stop-shop for learning about how to get started developing rich, interactive mashups on your web site quickly using Excel Web App and the power of Excel formulas for calculation.
