Earlier this month, Microsoft held its TechFest event where Microsoft Research team members showed a number of their projects. One of those efforts that was released to the public involved automating various tasks inside the Excel spreadsheet. As it turns out, the public reveal of this Excel research project may have been just the tip of the iceberg in terms of what Microsoft is working on for future versions of the spreadsheet application. MSFTKitchen has now posted yet another leaked video from Microsoft TechFest, showing off a previously private demo of yet another Excel research project.
