    The purpose of this research is to determine if the use of the Excel spreadsheet influences the academic performance of the mathematics area of the ninth grade students of the Nuevo Futuro Juvenile Educational Institution; Medellín-2014. It is an investigation of explanatory type, pre-experimental design, with pre-test / posttest, with a single group. This population is composed of 67 students and the sample is census. In the data collection a test instrument was used, standardized, validated by expert judgment and with a high reliability. In the obtained results it was verified that, the academic performance of the mathematics area, improved after the treatment was applied. In addition, it was evidenced that the numerical-variational and geometric-metric dimensions are the most difficult and easiest to learn, respectively, for grade level students. It is concluded, therefore, that the area of mathematics improves its academic performance by 76.12%, the dimension of the numerical-variational area improves the academic performance by 70.78%, the dimension of the geometric-metric area improves the Academic performance by 86.05% and the dimension of the random area by 80.01%.
