A well-known web based free Excel spreadsheet alternative, Google Documents is a suite of web-based programs. One of these program is Google Spreadsheet, and as you might expect from the name, it is Google’s free spreadsheet alternative.
Google Spreadsheet uses Google’s interface, which is not substantially similar to the interface of any other office application. It is web-based, so it opens up in your browser. The interface is not as slick as Microsoft Office Web Apps, but users on slower computers have reported that the Microsoft Office Web Apps do not run well, whereas Google Spreadsheet has no problem on slower machines.
Google Spreadsheet includes all the basic functionality you’d expect. You can format spreadsheets and enter formulas. Spreadsheet also includes some advanced features that you don’t find in Office Web Apps, like the ability to include charts and images. These features are less detailed than in a full version of Office or OpenOffice.org, but they’re impressive nonetheless.
Collaboration is also a major feature included Google Spreadsheet. It is possible to share files easily with other Google users so that data can be quickly exchanged. Alternatively, you can share a file as read-only. This is useful because it lets people view data in a browser, free of file format compatibility issues.
