SaaSy eXpresso gives a jolt to Excel workgroups
Smooth collaboration service enables Excel file sharing, provides change alerts, and offers compliance auditing
eXpresso provides some functions that help organize your work. After quickly adding tags to categorize files, I easily searched for all files marked with, say, "2008 Division Budgets." Additionally, this service provides traditional folders for organizing spreadsheets.
I used the Compare feature extensively, and it turned out to be one of my favorites. That's because it shows two spreadsheets side-by-side and color-codes what's changed, deleted, or added between them.

I picture Microsoft countering that collaborative features are available to Excel users through Microsoft Office SharePoint Server (MOSS) 2007, which also provides workflow capabilities. Fair enough, but the cost and complexity of MOSS outstrips eXpresso by leaps and bounds. At the other extreme, free services such as Google Docs & Spreadsheets can't match eXpresso's auditing. eXpresso also trumps these solutions with its collaborative capabilities and alerts.
Overall, eXpresso provides a very satisfying experience. And from eXpresso's road map, it appears the few gaps, including workflow, will be addressed.
