If you are accustom to using Excel spreadsheets in your office, you have probably already asked yourself why there isn’t an online community in which you and your coworkers can compare your data. Well, now there is. The Menlo Park, CA based corporation eXpresso brings you eXpresso Spreadsheet Communities, an interactive service which allows workgroups to upload, modify, and compare, and store their respective spreadsheets. eXpresso Spreadsheets bring several new options to the table which enhance Excel and empower its users. For example, the site’s chat function also allows you to host group chats in which you can exchange opinions and comments, and the “Alerts” function sends you a message every time your spreadsheet is modified or commented on by another group member. Best of all, eXpresso can be accessed anytime, anywhere, is free of charge, and no installation is necessary for those who are already Excel users.
