LinkedCells is an Excel add-in that lets you share Excel data with colleagues. No more e-mailing spreadsheets back and forth. All you need is Excel and an internet connection. Your colleagues can use your data in their spreadsheets or, they can share data with you, and you can use that data directly in your own spreadsheet. You'll always have access to up-to-date information. It's easy to use -- you continue working in Excel.
