If you have access to a PC and an internet connection then your options for working with an Excel spreadsheet away from your desk are good – thanks to the Microsoft Office WebApps. Even though many of the advanced Excel tools you are used to using offline won’t be accessible online they won’t be destroyed by opening a file in the Excel WebApp either. You can view charts and filtered table data and features such as the new Slicers in an Excel 2010 PivotTable can be used to work with the data.
Of all the cloud based apps, including Google Docs, the Microsoft WebApps are your best option for working with Excel spreadsheets in the cloud when you are away from your desk and the apps are free.
You can sign up for a free SkyDrive account at skydrive.live.com and that’s where you get access to the WebApps which include Excel, Word, PowerPoint and OneNote. I selected to upload this file then view it in the Excel viewer. To work on it beyond selecting options in the Slicers I can click Edit in Browser to open the file in the free cut down version of Excel online.
One benefit to using SkyDrive is that you can upload files from your local computer to SkyDrive where they are stored for you. You can work on the files online and later download them to your computer when you want to work on them there.
