The idea is that, when someone emails a spreadsheet to your iPad, the app will open it up—but not as a series of rows and columns. It will open the thing as chart or graph, and with a swipe of the finger, you can reformat the data into a new chart or graph. The hope is that this will make is easier for anyone to read a digital spreadsheet—an age-old computer creation that’s still looks like Greek to so many people.
