Most of our day jobs aren't nearly as amusing as life at Wernham Hogg and Excel doesn't make things any more exciting. But, if you're looking to spice up your spreadsheets, Microsoft's ExcelMashup.com may be just what you've been waiting for. The site lets you create apps of your very own using Redmond's various products. For example, you can combine some Excel JavaScript, a workbook stored on SkyDrive and a little HTML to create apps that run in a browser. Add a dash of Bing Maps and you've got a Destination Explorer! For the uninitiated, there are tutorials and for the showoffs a shared code space. There's even nifty Interactive Code Snippets for trying out bits of script before adding them to your own project. Want to make the cute girl in reception notice you? Coding your own apps in Excel won't help, but it'll probably land you in less trouble than putting Gareth's stapler in Jello again.
