I have worked with Microsoft excel for the 10 years and I don’t entertain errors since I am a science researcher. Accuracy, decency and punctuality is my ultimate aim since good name is better than riches. I have been using excel for my projects, assignment and thesis. I am a computational Material Scientist, which means I spend most of my time on the computer with a fast internet access. If there is any one best for the job, it is me. Thanks
