Welcome to the WorldWide Telescope Add-in for Excel

Suppose you have spatial data that is time-tagged, so your minimum data set is a location—latitude and longitude—and a date. And suppose your data is in an Excel spreadsheet. By installing the WorldWide Telescope Add-in for Excel, you can highlight and “push” your data into the visualization environment in seconds. Update your data, and the visualization updates automatically. Save the data, send it to a colleague, and they can see what you’re working on and add their data. The collaboration possibilities are many after just a few minutes of learning about the new Excel ribbon.
