I would like to be able to run an excel file with a handheld device. I am a forester and the timber cruising program I use is an excel file. Right now I have to hand write all of the field data in the woods and go back to my office to enter the information on my desktop. I would like to be able to enter the information directly while I am in the field to save time and be able to tell when I have enough data to be statistically accurate. Any advice?
